Researchers take step toward development of universal COVID-19 antibodies – PR Newswire

June 2, 2024

Texas Biomed and partners licensing new SARS-CoV-2 antibody targeting newest strains of COVID-19

SAN ANTONIO, May 30, 2024 /PRNewswire/ -- SARS-CoV-2, the virus that causes COVID-19 disease, continues to evolve and evade current vaccine and therapeutic interventions. A consortium of scientists at Texas Biomedical Research Institute (Texas Biomed), the University of Alabama at Birmingham (UAB) and Columbia University have developed a promising new human monoclonal antibody that appears a step closer to a universal antibody cocktail that works against all strains of SARS-CoV-2.

"This antibody worked against the original SARS-CoV-2 strain, Omicron and SARS-CoV, providing strong evidence that this antibody will continue to work against future strains, especially if paired with other antibodies," says Luis Martinez-Sobrido, Ph.D., a Professor at Texas Biomed and co-lead author of the research, which is published as a preprint on BioRXiv.

Antibodies are part of the human immune system that track, bind to and destroy extraneous material like viruses and bad bacteria. Human monoclonal antibodies are lab-made proteins that mimic the human process and stimulate the body to produce its own antibodies, enhancing the ability to fight back against illnesses.

While existing antibody treatments have helped many patients with COVID-19, some treatments have been rendered infective because the virus evolved and the antibodies could no longer physically bind to the targeted region in other words, the key no longer fit the lock.

The newly designed antibody, called 1301B7, is a receptor binding domain antibody, meaning it targets a region of the spike protein responsible for enabling the virus to bind and enter a cell. By targeting this region, these antibodies are essentially stopping the virus before they can infect a cell.

"The antibody binds to multiple positions within the receptor binding domain, which is thought to enable it to tolerate variations that occur in this domain as the virus continues to evolve," says James Kobie, Ph.D., an Associate Professor at UAB and co-lead author of the paper. The precise nature of how the antibody binds to the receptor binding domain was solved by Mark Walter, Ph.D., a Professor at UAB and co-lead paper author.

The monoclonal antibody is designed based on antibodies the UAB team isolated from patients infected with the Omicron variant of SARS-CoV-2. The teams at Texas Biomed and Columbia University tested the antibody against several variants including the original SARS-CoV-2 isolated in China, Omicron JN.1 and SARS-CoV.

In 2022, the researchers described a monoclonal antibody targeting a different partof the spike called the stalk. The researchers plan to next study what happens when they combine the two antibodies together, attacking the virus from different angles and hopefully preventing it from escaping neutralization.

"A single antibody therapy is not going to work, so we may have to try something similar to therapies being developed for other diseases like Ebola and HIV whereby two or three antibodies are combined to target different regions of the virus," explains Dr. Martinez-Sobrido.

They are also interested in adapting the antibodies into a preventative vaccine.

"We are also trying to design vaccines that would be able to induce these types of antibodies so we don't have to update vaccines regularly," says Dr. Martinez-Sobrido.

The consortium of scientists has filed a provisional invention patent for 1301B7 and is in the process of licensing it for commercialization.

Funding for this work was largely provided by the National Institutes of Health 1R01AI161175.

COVID-19 associated with higher risk of erectile dysfunction – News-Medical.Net

June 2, 2024

A recent study published in International Journal of Impotence Research reports that men previously infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus disease 2019 (COVID-19), are at a greater risk of developing new-onset erectile dysfunction.

As of April 2022, SARS-CoV-2 infected over 80 million individuals and caused over 970,000 deaths in the United States.

Long-term health consequences of COVID-19, which are collectively referred to as long-COVID, have been widely reported. Real-world evidence shows that people with long-COVID can experience a wide range of symptoms that can last for weeks, months, or even years after acute SARS-CoV-2 infection.

In addition to general symptoms of fatigue, post-exertional malaise, and fever, long-COVID is associated with respiratory, cardiovascular, neurological, digestive, and musculo-skeletal complications. A small number of initial reports have also reported a link between COVID-19 and erectile dysfunction in men, which might be attributed to long-term cardiovascular complications.

Existing literature indicates the persistent presence of SARS-CoV-2 viral particles in corporal tissue, the erectile tissue of the penis, several months after COVID-19 infection. This suggests a possible pathophysiological mechanism for erectile dysfunction in men with a history of COVID-19.

The IBM MarketScan is a large insurance claims database that includes over 215 million policy holders. In the current study, this database was used to identify men who were diagnosed with COVID-19 between January 2020 and January 2021 and subsequently diagnosed with new-onset erectile dysfunction.

The association between prior COVID-19 and new-onset erectile dysfunction was determined after controlling for common erectile dysfunction risk factors including age, prostate cancer, cardiovascular disease, hypogonadism, obesity, smoking, and diabetes mellitus. Bladder cancer, hypertension, hyperlipidemia, spinal cord injury, and geographic region were included in the analysis as additional covariates.

A total of 42,406 men with a history of COVID-19 were included in the study. A total of 45,119 age-matched men without prior COVID-19 were also included as experimental controls in the comparative analysis.

Men with a history of COVID-19 were more likely to have a history of diabetes, hypertension, hyperlipidemia, and hypogonadism as compared to those without COVID-19.

A total of 1,111 cases of new-onset erectile dysfunction were identified between January 2020 and January 2021. Among these cases, 54.1% were men with prior COVID-19 and 45.9% were men without COVID-19. The rates of new-onset erectile dysfunction in the COVID-19 and control groups were 1.4% and 1.1%, respectively.

After controlling for potential confounding factors like diabetes, cardiovascular disease, smoking, obesity, hypogonadism, thromboembolism, and malignancy, the multivariate analysis showed a significant independent association between previously diagnosed COVID-19 and increased risk of new-onset erectile dysfunction.

Men with a history of COVID-19 were at a 27% increased risk of developing erectile dysfunction, which is comparable to a new diagnosis of diabetes following recovery from COVID-19. Existing literature indicates that endothelial dysfunction caused by SARS-CoV-2 infection might be responsible for the development of erectile dysfunction.

Some studies have also highlighted the potential involvement of angiotensin converting enzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2), which are human cell membrane proteins responsible for SARS-CoV-2 entry. These proteins are ubiquitously expressed in endothelial cells and might be involved in the pathogenesis of COVID-19-related vasculogenic erectile dysfunction.

In the IBM MarketScan commercial claims database, medical visits and associated diagnoses are captured longitudinally as long as insurance is billed. This allows for an accurate and adequate capturing of longitudinal patient data, which further reduces the risk of underestimating the effect of prior COVID-19 on erectile dysfunction development.

Since the current study included patient data captured during the initial nine months of the pandemic, the analysis did not consider COVID-19 vaccination, home testing, and SARS-CoV-2 variants as potential confounding factors. Thus, these findings may be more representative of the association between COVID-19 and new-onset erectile dysfunction prior to widespread vaccine uptake, home testing, and variant strain transmission.

Therefore, future studies with longer follow-up durations are needed to determine whether COVID-19 vaccination can reduce the risk of new-onset erectile dysfunction at the population-level, as well as the variant-specific association between COVID-19 and erectile dysfunction.

COVID-19 home or outpatient tests in which an insurance claim is not submitted are not captured in the IBM MarketScan database. Thus, there remains a possibility that the rate of COVID-19 is underestimated.

Individual medical records are not included in the database; therefore, the researchers could not specifically assess the morbidity associated with each infection. These issues should be considered in future studies to more conclusively understand the impact of COVID-19 on new-onset erectile dysfunction.

In communities of color, long-covid patients are tired of being sick and neglected – The Washington Post

June 2, 2024

A mild covid infection at the start of the pandemic has thrown Jeanine Hayss immune system out of whack, she said, as her husband ticked off ailments the way drug commercials list side effects.

Chronic hives. Hair loss. Tinnitus. Severe nerve pain. Extreme fluctuations in blood pressure. Allergic reactions to synthetic fabrics and processed foods.

In every room of their house, the couple keep an air purifier and EpiPen, both things they travel with, too. And Hays always carries an extra set of clothes just in case what shes wearing becomes unbearably itchy. I definitely still feel like a toddler in that way, she said.

Bryan and I are learning to live with long covid, the 45-year-old said of her high school sweetheart turned husband. Our way of life is much different.

It has been four years since covid began burdening people with lingering symptoms often dismissed by mystified medical providers who were dubious and unwilling to help especially when treating patients of color, according to clinicians and public health researchers.

For patients of color, it is an all-too-familiar and maddening story.

Health-care experts and medical studies have found that racist myths about Black people having higher pain tolerance, coupled with physicians biases, mean Black patients are more likely to be seen as drug-seeking and described negatively in electronic medical records. That is true when it comes to routine diagnoses, and clinicians and public health researchers believe the same to be true with long covid, even as its definition remains very much a work in progress.

Its bad enough patients of color are coping with a debilitating illness, they said. Its all the more devastating, they said, to feel like theyre being erased from medical records, public imagination and policy considerations. Researchers say that in many cases, people are not even being formally diagnosed, meaning theyre suffering and not getting help.

Estimates of long covids prevalence vary widely. A recent report from the Centers for Disease Control and Prevention showed about 1 in 14 adults said in 2022 that they had ever experienced long covid.

While the coronavirus wreaked havoc on communities of color especially at the dawn of the pandemic research has suggested that the misery of long covid is more equally visited upon various communities. A 2023 analysis of nearly 5 million U.S. patients by The Washington Post and research partners found virtually no difference among the percentages of Black, White and Latino patients who sought medical care for symptoms associated with long covid within several months of being infected.

But public health experts caution that those numbers almost certainly dont tell the full story. The data, they warned, may say as much about who is believed by their provider, who can doctor-shop until they are taken seriously and who has the language to describe their symptoms to medical personnel.

People had all these things happening in their body, but they hadnt heard the term long covid from a provider, said Linda Sprague Martinez, a professor and health equity researcher who has studied the impact of long covid on Black and Latino communities in Massachusetts.

As part of her research, Sprague Martinezs team conducted 11 focus groups last year: two in English and nine total in Spanish, Portuguese, Haitian Creole and Cape Verdean Creole. In the focus groups not conducted in English, she said, they found that most people had not heard of long covid before that day. The main culprit, she said: a lack of medical information in languages other than English, and language barriers at health-care facilities and online.

They were going to the doctor and sometimes werent being taken seriously, she said, adding that some people were told to get on with their lives but not given help to do so. You need a doctor who believes you, who thinks youre not just being lazy, she said. Even if a provider who wants to help can be found, patients might lack the money or time off to receive a specialists care.

Sprague Martinez said data at the time found that most patients seeking care at long-covid clinics and recovery centers in Massachusetts were White people who spoke English, had private insurance and were from out of state.

Who gets diagnosed with long covid, its socially and economically skewed, said Sprague Martinez, who now runs the Health Disparities Institute at UConn Health in Connecticut. If we are only engaging White, middle-class, English-speaking America in treatment, we dont yet understand the full impact.

Jacqui Lindsay, a consultant working with the National Institutes of Healths RECOVER study on long covid, said the national research pool continues to inadequately represent Black, Latino, Native American, rural, immigrant, LGBTQ+ and disability communities and that health equity has not been sufficiently addressed.

Its just like the early days of covid. The data infrastructure is not there. A coordinated communication strategy is not there, said Lindsay, who represents the Boston COVID Recovery Cohort as part of the NIH initiative. And, as a consequence, the infrastructure for clinical care and support is not there.

Kanecia Zimmerman, who oversees the RECOVER Clinical Trials Data Coordinating Center at Duke University, said measures have been taken in the research to try to ensure that diverse communities are represented at every level of the research ecosystem.

Zimmerman, a pediatrician and internist who began working with the federal initiative in 2022, said sites in communities of color with a diverse workforce were identified to help enlist clinical trial participants. She said researchers created bilingual recruitment materials, including outreach videos, in English and Spanish, and made sure study participants were paid at research sites so they were compensated as fast as possible.

Were not where we want to be, Zimmerman said. We should be trying to reach rates of enrollment within the Black community and within the Hispanic community that are consonant with covid rates. We have not reached those targets.

For Hays and her husband, Bryan Mason, their journey began in March 2020 when they got covid about the same time. Back then, Mason was the sicker of the two. His lungs filled with so much fluid that one was pushing the other one out of alignment, he said. Meanwhile, his wife thought she had just a stomach bug.

Her husband recovered, but Hays started developing what she called very strange symptoms. When she stepped out of the shower and onto the tile floor, it felt like my feet were on fire, she said.

She started breaking out in hives. Then came the anaphylactic reactions to foods shed eaten most of her life, and difficulty breathing the air inside their prewar Brooklyn apartment. Eventually, they were forced to move.

Then, at the end of 2020, things took a turn for the worse. She developed sores in her throat and on her tongue and lost the ability to eat and speak. Theres still parts that are missing for me because of brain fog, she said.

Mason was calling doctor after doctor, becoming an amateur medical researcher and patient-care coordinator. Hays was able to get an appointment with a notable allergist, but that ray of hope was dashed. The doctor wouldnt let Mason accompany his wife to the appointment, so she went alone with notes hed jotted down because I had a lot of holes in terms of things I remembered, she said.

Then, the doctor, a White woman, insisted Hays had herpes.

I was like, Wait. What? she recalled, wondering if maybe shes doing some study on Black women with herpes.

Not that it mattered, she said, because clearly she wasnt caring at all about what was going on with me. She just kept going, No, I really think that you have herpes. Take Benadryl. Youll be fine. The doctor, however, never tested her for the viral illness, Hays said, adding that I was in tears.

It wasnt until she began to receive care and a long-covid diagnosis at the Center for Post-COVID Care at Mount Sinai in New York in March 2021 that things began to turn around, Hays said. The couples ordeal exemplifies the unpredictable nature of the damage the coronavirus can cause, with some people getting very sick while others show no symptoms at all. Now, Hays is able to walk again. Physical therapy keeps at bay the immobilizing feeling of bees inside your body buzzing all the time, she said.

It can be difficult to determine just how many people in the United States have long covid a wide-ranging constellation of symptoms that can persist for months or years as it remains an underdiagnosed condition that researchers and clinicians still struggle to understand.

New or worsening symptoms lasting two to three months tend to be the magic number when determining if someone has long covid, said Daniel Lewis, a California internist who founded and leads the Black Physicians Council of Providence Facey Medical Group, which provides care to the Santa Clarita, San Fernando and Simi valleys in California.

A 2023 study showed that more than 65 million people worldwide at least 15 million of them working-age Americans had endured long covid. Most were 36 to 50 years old, and most experienced only mild covid cases that didnt require hospitalization.

For millions of patients of color, the pandemic was a mass disabling event a fact many felt was widely ignored by policymakers, employers and society writ large. Long-covid sufferers say their pain has been dismissed. Their experiences downplayed. Their isolation intensified.

Chimre Sweeney said she was sure thats what her medical records reflected after a two-year odyssey that started with the fight to have her initial coronavirus infection noted in her records, a battle she repeated with long covid.

The former Baltimore middle school teacher said she was told in March 2020 that her symptoms sore throat, stuffy nose, headache, back pain couldnt be covid because she didnt have a fever, cough or shortness of breath.

I wasnt tested, she recalled. I was told, Oh, its a sinus infection.

And thats how it went during repeated trips to the doctor and emergency room, with providers insisting she didnt have covid even as they told her to quarantine for 14 days just in case. When she insisted that something was wrong, Sweeney said, she was told that youre just anxious because you cant teach or that I needed a psychiatric evaluation.

Meanwhile, she said, her symptoms worsened, leaving her unable to drive, barely able to see and 30 pounds lighter. Things improved, she said, only when she started emailing community leaders begging for help and hired a patient advocate.

Her long-covid diagnosis arrived in April 2022, she said.

I cried that day because I was like, Thank you, God! she said. Having that diagnosis got the ball rolling on everything else for me Social Security, this retirement. Because I was poor. I went from making $65,000 to nothing.

The 41-year-old said she has not stepped back into the classroom because extreme fatigue, brain fog and migraines persist. Because shed invested five years in the public school system, Sweeney said, she was able to retire with full benefits, including long-term disability.

This comes as researchers with the Urban Institute have found that about 40 percent of adults with long covid dont have enough to eat and about a quarter struggle to pay rent and utilities.

For those patients insured or not who find themselves in front of neurologist Joey R. Gee, theres one treatment thats more compassionate than clinical. And that, he said, is to validate how they feel.

Gee, who works at Providence Mission Hospital in Orange County, Calif., said he sees a common denominator in the experiences of patients of color seeking pain management and treatment for long covid: A huge disparity in treatment. The most common symptoms whether it be pain, fatigue, brain fog or pulmonary symptoms were not really looked at seriously.

Instead, he said, referring doctors tend to take a wait-and-see approach, which can be very invalidating.

Gee experienced debilitating, long-term effects from multiple coronavirus infections. His vocal cords hemorrhaged after his first infection, leaving him unable to speak for four months.

Researchers and clinicians have found that covid can turn once-manageable conditions into debilitating ailments, he said. Compounding the problem, he added, are insurers who dont really feel its a real condition to handle. That is a huge barrier.

Gabriel San Emeterio knows all too well what its like trying to battle insurers to cover the cost of care for debilitating illnesses. For years, San Emeterio was a Medicaid recipient who received treatment at a clinic dedicated to helping low-income patients with HIV.

Its not bad in terms of HIV, San Emeterio said about care provided at the clinic. But that was not necessarily the case for San Emeterios other conditions chronic fatigue, psoriatic arthritis, fibromyalgia and Lyme disease which San Emeterio now believes include long covid.

The 43-year-old, who now has employer-based insurance but continues with the same doctors at the clinic, avoided a coronavirus infection until summer 2022. Nearly a year later, San Emeterio still hadnt returned to baseline and started experiencing new symptoms. Light sensitivity. Dizziness when scrolling webpages. Daily headaches. Intense pain. Brain fog.

So San Emeterio went to the doctor, who tells me Im prediabetic. So I was like, Could it be long covid? Im still struggling, and my health is not the same.

The concern was casually dismissed, San Emeterio recalled, adding that the doctor said, Well, you already had a lot going on before you got covid, so do we really need to put long covid in your electronic medical records?

San Emeterio said it remains unclear whether the medical records reflect a diagnosis of long covid even after a second bout of covid in December. This time, at least, the doctor offered up a long list of specialists even if it wasnt accompanied with a formal diagnosis.

Angela Meriquez Vzquez said she pays out of pocket for most of the medicines she needs because of long covid. Vzquez said shes allergic to changes in temperature and air pressure, most foods and the preservatives in manufactured medicine, which is why she has hers specially compounded.

The sun, she said, gives her a rash that feels like someone lit a match under my skin. So, she receives a four-hour IV infusion of Benadryl weekly, she said, just so my immune system doesnt freak out.

Vzquez got covid early in the pandemic when tests were hard to come by and people were discouraged from seeking care unless critical. It was wild, she said. I would forget what people were saying as they were saying it.

It was also a time, said the 36-year-old from Los Angeles, when she experienced discrimination like never before. In the days after her covid infection waned, new symptoms materialized. She was dizzy, short of breath and suffering from heart palpitations.

She went to the emergency room several times, only to be scolded for taking resources from people who are really sick, she recalled, adding that providers were more focused on her confusion and inability to communicate than complaints that my feet are swollen purple and warm.

I was asked by a nurse if I needed an interpreter, said Vzquez, who identifies as Chicana. I dont speak with an accent. Eventually, I spent the night in the hospital for what was later diagnosed to be a series of ministrokes.

Now, she has a life-or-death fear of the medical system and worries that physicians have found a new reason to dismiss her concerns her medical diagnosis of long covid.

COVID-19 boosters targeting omicron subvariants remain effective, but wane over time – News-Medical.Net

June 2, 2024

Boosters that target the omicron subvariants of SARS-CoV-2 are still providing reasonably durable protection against infection, hospitalization and death from COVID-19, according to new data from a study led by researchers at the UNC Gillings School of Global Public Health.

Published today in the New England Journal of Medicine, the study found that COVID-19 boosters targeting the XBB.1.5 subvariants were most effective one month after receiving one. After four weeks, the vaccines were 52.2% effective at preventing infection and 66.8% effective at preventing hospitalization.

The vaccines were also highly effective at preventing death, but exact certainty was hard to quantify given the small number of deaths reported during the study period.

After peaking at four weeks, booster effectiveness waned over time. Effectiveness at preventing infection decreased to 32.6% after 10 weeks and 20.4% after 20 weeks, while effectiveness at preventing hospitalization decreased to 57.1% after 10 weeks.

Danyu Lin, PhD, Dennis Gillings Distinguished Professor in the Department of Biostatistics at the Gillings School, is lead author on the study. Additional co-authors include Yangjianchen Xu at the Gillings School; Yi Du, PhD, Sai Paritala, PharmD, and Matthew Donahue, MD, from the Nebraska Department of Health and Human Services; and Patrick Maloney, PhD, from the University of Nebraska Medical Center.

Using data from the Nebraska Electronic Disease Surveillance System and the Nebraska State Immunization Information System, the research team studied the efficacy of vaccination before and after Oct. 25, 2023, when the JN.1 variant began to emerge.

Vaccine effectiveness was lower in the second group, suggesting that the booster was less protective against the now-dominant JN.1 strain.

The JN.1 subvariant has been the dominant strain in the United States this year. The relatively low effectiveness of the XBB.1.5 vaccines against the JN.1 subvariant, together with the waning effectiveness over time, underscores the need for new vaccines targeting the JN.1 strain."

DanyuLin, PhD, Dennis Gillings Distinguished Professor, Department of Biostatistics, Gillings School

Lin says the Food and Drug Administration's general strategy is to deploy new COVID-19 vaccines annually in the fall that target the circulating strains in the spring, and that the findings in this study may contribute to this decision.

"It would be worthwhile to deploy new vaccines this fall that target the JN.1. strain," he said.

COVID-19 virus concentrations steadily increasing in Colorado wastewater – Colorado Public Radio

June 2, 2024

Concentrations of the virus responsible for COVID-19 are on the rise in 29 wastewater treatment facilities in the state as of Wednesday, according to state data.

Nearly every utility along the Front Range from Fort Collins to Colorado Springs reported an uptick in viral concentrations this week. Twenty-one of those utilities have seen a steady increase, which means the viral concentrations of the two most recent samples show a statistically significant increase of RNA from SARS-CoV-2, the virus that causes COVID, relative to previous samples from that facility.

Higher levels of the virus can mean that there is a rise of cases in the community, but the state health department said wastewater testing is meant to supplement existing COVID metrics case data, hospitalization data, test positivity data and variant data. There are limitations to wastewater data insofar as viral concentration levels cant be compared between facilities because of differences in collection times and the size of the population being served.

Still, wastewater sampling is a test that shows in real-time how COVID might be moving through a community. As of May 1, the federal requirement that hospitals report the number of people admitted with COVID ended, leaving the data and the picture of COVID in a community incomplete.

Starting with the data released Wednesday, the Colorado Department of Public Health and Environment is now doing the job of collecting the information on new hospital admissions that appear on its dashboard.

Mid-May saw the lowest number of COVID hospitalizations with 73. That number has ticked back up to 88 people as of Tuesday.

The number of cases and the rate of positive COVID tests have also risen in the last month. Still, those numbers dont give a complete picture either, especially of a significant number of Coloradans who test for COVID at home and dont report test results to health officials.

The precautions are the same as youve heard since 2020, wash your hands and cough into your elbow, stay home if you feel ill, and get vaccinated against COVID-19 and other infectious diseases.

COVID is rising in California. Here’s how to protect yourself from FLiRT subvariants – Los Angeles Times

June 2, 2024

There are growing signs of an uptick in COVID-19 in California thanks to the new FLiRT subvariants.

Its far too early to know if FLiRT will be a major change in the COVID picture, and so far the impacts have been small.

But health officials are taking note and are urging Californians especially those at risk to be prepared.

Heres rundown of what we know and how you can protect yourself.

The FLiRT subvariants officially known as KP.2, KP.3 and KP.1.1 have overtaken the dominant winter variant, JN.1. For the two-week period that ended Saturday, they were estimated to account for a combined 50.4% of the nations coronavirus infections, up from 20% a month earlier.

Despite their increased transmissibility, the new mutations dont appear to result in more severe disease. And the vaccine is expected to continue working well, given the new subvariants are only slightly different from the winter version.

Its been quite a while since weve had a new dominant variant in the U.S., Dr. David Bronstein, an infectious diseases specialist at Kaiser Permanente Southern California told The Times earlier this month. With each of these variants that takes over from the one before it, we do see increased transmissibility its easier to spread from person to person. So, thats really the concern with FLiRT.

Doctors say they are not seeing a dramatic jump in severely ill people, and COVID levels still remain relatively low. But there are signs of a rise in infections that could lead to the summer coronavirus season beginning earlier than expected.

Over the seven-day period that ended May 20, about 3.8% of COVID-19 tests in California came back positive; in late April, that share was 1.9%. (Last summers peak test-positive rate was 12.8%, at the end of August.)

In San Francisco, infectious disease doctors are noticing more people in the hospital with COVID-caused pneumonia.

The Los Angeles County Department of Public Health has also started to see a very small uptick in cases in recent days. And Kaiser Permanente Southern California is reporting a small increase in outpatient COVID-19 cases.

Doctors urged people to consider getting up to date on their vaccinations particularly if they are at higher risk of severe complications from COVID-19.

In California, just 36% of seniors ages 65 and older have received the updated COVID-19 vaccine that first became available in September. The U.S. Centers for Disease Control and Prevention has urged everyone ages 6 months and older to get one dose of the updated vaccine. A second dose is also recommended for those ages 65 and older, as long as at least four months have passed since their last shot.

Its especially important that older people get at least one updated dose. Of the patients he has seen recently who had serious COVID, said UC San Francisco infectious diseases specialist Dr. Peter Chin-Hong, all of them hadnt gotten an updated vaccine since September, and were older or immunocompromised.

Avoid sick people. Some sick people might pass off their symptoms as a cold, when it could be the start of a COVID-19 illness.

Test if youre sick, and test daily. Its sometimes taking longer after the onset of illness for a COVID-19 rapid test to show up as positive. Consider taking a rapid COVID test once a day for three to five consecutive days after the onset of cough-and-cold symptoms, said Dr. Elizabeth Hudson, regional chief of infectious disease at Kaiser Permanente Southern California. Doing so can help the sickened person take measures to later isolate themselves and limit spread of the illness to others.

Have a plan to ask for Paxlovid if you become ill. Paxlovid is an antiviral drug that, when taken by people at risk for severe COVID-19 who have mild-to-moderate illness, reduces the risk of hospitalization and death.

Masks are much less common these days but can still be a handy tool to prevent infection. Wearing a mask on a crowded flight where there are coughing people nearby can help reduce the risk of infection.

The U.S. Centers for Disease Control and Prevention has recently eased COVID isolation guidance, given that the health impacts of COVID-19 are lower than they once were, due to the availability of vaccines, anti-COVID medicines such as Paxlovid and increased population immunity.

There are fewer people getting hospitalized and dying, and fewer reports of complications such as multi-inflammatory syndrome in children.

Still, doctors say it remains prudent to take common sense steps to avoid illness and spreading the disease to others, given that COVID still causes significant health burdens that remain worse than the flu. Nationally, since the start of October, more than 43,000 people have died of COVID; by contrast, flu has resulted in an estimated 25,000 fatalities over the same time period.

While the prevalence of long COVID has been going down, long COVID can still be a risk any time someone gets COVID.

Heres a guide on what to do if you get COVID-19:

The CDC says people should stay home and away from others in their household until at least 24 hours after their respiratory viral symptoms are getting better overall, and they have not had a fever (and are not using fever-reducing medicine). Previously, the CDC suggested people with COVID isolate for at least five days, and take additional precautions for a few more days.

In terms of deciding when symptoms are getting better overall, whats most important is the overall sense of feeling better and the ability to resume activities, the CDC says. A lingering cough by itself can last beyond when someone is contagious, the CDC said.

The Los Angeles County Department of Public Health also recommends testing yourself using a rapid test, and getting a negative result, before leaving isolation.

The agency also suggests staying away from the elderly and immunocompromised people for 10 days after you start to feel sick.

People who have recovered from COVID-19 may still be contagious a few days after they have recovered. The CDC suggests taking added precautions for five days after they leave their household and resume spending time with others to keep others safe. They include:

The L.A. County Department of Public Health says people with COVID-19 need to wear a well-fitting mask for 10 days after starting to feel sick, even if signs of illness are improving, to reduce the chance that other people could get infected. Masks can be removed sooner if you have two consecutive negative test results at least one day apart, the agency says.

COVID rebound can occur when people with COVID-19 feel better, but then start to feel sick two to eight days after theyve recovered. Some people may also test positive again. COVID rebound can result in you becoming infectious again, capable of infecting those with whom you interact.

Rebound can happen whether or not you take Paxlovid.

Officials say if you feel sick again after having recovered from COVID, go back to following the same instructions to stay at home and away from other people during the first phase of the illness.

The CDC says if you never had any symptoms, but test positive, take additional precautions for the next five days, such as masking up, testing, increasing air circulation, keeping distance and washing hands often.

The L.A. County Department of Public Health recommends wearing a well-fitting mask for 10 days after testing positive for COVID-19, and also avoiding contact with any high-risk people for 10 days after starting to feel sick, such as the elderly and immunocompromised people. You can remove your mask sooner if you have two consecutive negative tests at least one day apart.

L.A. County health officials recommend close contacts of people who have COVID-19 wear a well-fitting mask around other people for 10 days after their last exposure. They suggest getting tested three to five days after their last exposure.

Congress turns to Fauci after grilling an NIH scientist over COVID emails – University of South Florida

June 2, 2024

Former National Institutes of Health official Dr. Anthony Fauci has faced many hostile questions from members of Congress, but when he appears before a House panel on Monday, hell have something new to answer for: a trove of incendiary emails written by one of his closest advisers.

In the emails, David Morens, a career federal scientist now on administrative leave, described deleting messages and using a personal email account to evade disclosure of correspondence under the Freedom of Information Act.

i learned from our foia lady here how to make emails disappear after i am foiad but before the search starts, so i think we are all safe, Morens wrote in a Feb. 24, 2021, email. Plus i deleted most of those earlier emails after sending them to gmail.

The pressure is on as Fauci himself prepares to appear before a House subcommittee exploring the origins of COVID-19. The NIH, a $49 billion agency that is the foremost source of funding in the world for biomedical research, finds itself under unusual bipartisan scrutiny. The subcommittee has demanded more outside oversight of NIH and its 50,000 grants and raised the idea of term limits for officials like Fauci, who led the National Institute of Allergy and Infectious Diseases, an NIH component, from 1984 to 2022.

Lawmakers are likely to put Fauci on the spot about Morens emails at a time when Republicans are questioning NIHs credibility and integrity. Even Democrats have cautioned the agencys leaders.

When people dont trust scientists, they dont trust the science, Rep. Deborah Ross (D-N.C.) told Morens.

The subcommittee has yet to turn up evidence implicating the NIH or U.S. scientists in the pandemics beginnings in Wuhan, China. Nor has its work shed light on the origin of the virus.

But in a May 28 letter to NIH Director Monica Bertagnolli, the subcommittees chairman, Rep. Brad Wenstrup (R-Ohio), said the evidence suggests a conspiracy at the highest levels of NIH and NIAID to avoid public transparency regarding the COVID-19 pandemic.

Rep. Jill Tokuda, a subcommittee Democrat from Hawaii, said the evidence shows no such conspiracy. She predicted the bipartisan criticism of Morens, 76, will give way to a clash of intentions at the hearing as Republicans try to pin COVID on Fauci.

For them, I think this is their moment to, again, bring a lot of these baseless, false allegations to the front, Tokuda said.

On May 29, Wenstrup asked Fauci to turn over personal e-mails ahead of his testimony.

Here are things to know as the subcommittee gears up for Faucis appearance.

What Is the Subcommittee Looking For?

The Select Subcommittee on the Coronavirus Pandemic is supposed to be investigating how the pandemic started and the federal governments response. That includes such hot-button issues as vaccination policies and school closures.

A central question is whether the COVID virus leaped from animals to humans at a market in Wuhan, China, or spread from a leak at the nearby Wuhan Institute of Virology. The Wuhan lab received funding from an NIH grant recipient called EcoHealth Alliance.

The congressional probe is in some ways an extension of the nations political, cultural, and scientific battles arising from the pandemic.

The Republican-led subcommittee has been examining NIHs performance and that of Fauci, who advised both former President Donald Trump and President Joe Biden, becoming the face of many of the governments most polarizing pandemic policies.

The panel called for the government to cut off EcoHealths funding, a process the Department of Health and Human Services recently initiated.

EcoHealths president, Peter Daszak, was Morens friend and the recipient of many of the emails under scrutiny. A wildlife biologist credited with helping to develop the first COVID antiviral drug, remdesivir, Daszak said he and his organization did nothing wrong.

We were so accurate in our predictions that a bat coronavirus would emerge from China and cause a pandemic, that when it did, were dragged in front of the crowd with their pitchforks and blamed for it, Daszak said in an interview.

Explosive Hearing Spotlights NIH Scientist's Emails About Evading FOIA

Whats at Stake for NIH?

The Republican-led subcommittee is challenging NIHs credibility. The agency performs and funds a wide variety of medical and scientific research, work that is often the foundation of new medicines and other treatments, and has long enjoyed bipartisan support from Congress. The agency is home to the Cancer Moonshot, a Biden priority.

As head of NIAID and a presidential adviser, Fauci helped guide the public during the pandemic on measures to avoid infection, such as mask-wearing and maintaining physical distance.

But at a May 22 hearing, Wenstrup said Faucis NIAID was, unfortunately, less pristine than so many, including the media, would have had us all believe.

In his letter to Bertagnolli, Wenstrup said there was evidence that a former chief of staff of Faucis might have used intentional misspellings such as a variant of EcoHealth to prevent emails from being captured in keyword searches by FOIA officials.

Wenstrups office did not respond to questions or an interview request.

An aide to the top Democrat on the subcommittee, Rep. Raul Ruiz of California, said he was unavailable for an interview.

Why Were Morens Emails Alarming?

The emails show a pattern of trying to shield communications from public disclosure.

We are all smart enough to know to never have smoking guns, and if we did we wouldnt put them in emails, and if we found them wed delete them, Morens wrote on June 16, 2020.

The best way to avoid FOIA hassles is to delete all emails when you learn a subject is getting sensitive, he wrote on June 28, 2021.

Some of Morens emails included sexual or sexist remarks, including one from December 2020: Beverage is always good, and best delivered by a blonde nymphomaniac. In another email, discussing how former Centers for Disease Control and Prevention Director Rochelle Walensky got her job, he remarked, Well, she does wear a skirt.

Morens apologized at the May 22 hearing and called some of what he wrote misogynistic.

Some of the emails Ive seen that you all have provided look pretty incriminating, he testified.

Asked if he ever sent information related to COVID to Faucis personal email, he said he didnt remember but might have.

Morens said some of his comments were snarky jokes intended to cheer up his friend Daszak, the EcoHealth president, who was receiving death threats over media coverage of his organizations relationship with the Wuhan lab.

Morens testified that he didnt knowingly delete official records.

Ross, the North Carolina representative, said the emails inflict serious damage on public trust for the entire scientific enterprise. She said the dangers can be seen in eroding public confidence in vaccines, contributing to recent outbreaks of measles.

Rep. Debbie Dingell (D-Mich.) said Morens showed disdain for the Freedom of Information Act. The subcommittees investigation has been an unfounded effort to pin the blame for the pandemic on NIH and NIAID, and Morens emails have helped blur the issues, she said.

Do the Emails Reveal the Origins of COVID?

No, as Democrats have emphasized.

In a way, Morens correspondence undercuts allegations that people at the top of NIAID covered up a lab leak in Wuhan.

None of Morens emails describe any effort to suppress evidence of a lab leak and, in an email sent from a private account, he ridiculed the idea, calling it false to the point of being crazy. But the subcommittees senior Democrat, Ruiz, criticized Morens for dismissing the lab leak theory.

Unless and until we see specific evidence on the origins of the virus that causes COVID, the scientific process requires that we examine all possible hypotheses with objectivity, Ruiz said.

Covid wave shapes up for summer but is unlikely to spark concern – The Washington Post

May 27, 2024

By now, its as familiar as sunscreen hitting the shelves: Americans are headed into another summer with new coronavirus variants and a likely uptick in cases.

This is shaping up to be the first covid wave with barely any federal pressure to limit transmission and little data to even declare a surge. People are no longer advised to isolate for five days after testing positive. Free tests are hard to come by. Soon, uninsured people will no longer be able to get coronavirus vaccines free.
