Coronavirus updates: Fauci concerned about current U.S. trends; universities become the latest hotspots – CNBC

September 12, 2020

The U.S. reported more than 35,200 new cases of the coronavirus on Thursday, its highest daily tally since Sep. 5, according to data compiled by Johns Hopkins University. The holiday weekend likely impacted the data over the past few days and is only now beginning to stabilize. The seven-day average of daily new cases has fallen to 35,219, down more than 12% compared with a week ago.

Trump says everyone knew the coronavirus was airborne in February: It’s ‘no big thing’ – CNBC

September 12, 2020

President Donald Trump on Thursday defended comments he made to reporter Bob Woodward in early February in which he acknowledged the coronavirus "goes through air" despite publicly downplaying the threat in public and telling Americans the virus would disappear.

At the time of Trump's private comments to Woodward, it was unclear how the virus spread and scientists were debating whether and to what degree it could spread through the air. Trump, however, insisted on Thursday that it was widely understood that the virus spread through particles in the air before he made his private remarks in a Feb. 7 taped phone call between Woodward and the president.

"This is stuff that everyone knew. There's a report that I have here someplace where China said it was airborne earlier than the statements I made. People knew it was airborne. This was nothing," he said Thursday in a White House press briefing. "When I say it was airborne, everybody knew it was airborne. This was no big thing. Read the reports. China came out with a statement that it was an airborne disease. I heard it was an airborne disease. I assumed it early on."

In response to a question about what report the president was citing, a White House official pointed CNBC to a Jan. 30 report from TIME. The report said Chinese authorities announced on Jan. 7 that they had isolated the virus, which "belongs to the coronavirus family...and spreads via airborne droplets."

A day after Trump's private comments to Woodward, Chinese state media The China Daily reported thatZeng Qun, deputy head of the Shanghai Civil Affairs Bureau, said the virus can spread through aerosol transmission, suggesting the virus was airborne in some situations. But the next day, officials from the Chinese Center for Disease Control and Prevention disputed the earlier report, according to The China Daily, saying that there was no evidence the virus could spread through airborne particles.

Early in the outbreak, scientists stressed how little was known about the virus, which emerged in Wuhan, China, at the end of December. In the nine months since the virus emerged, scientists have learned much about how it spreads and the disease it causes but continue to emphasize that it is a relatively new virus and much remains unclear. The role that airborne transmission of the virus plays in general spread has been among the more contentious questions debated.

The U.S. Centers for Disease Control and Prevention says the virus is primarily spread through respiratory droplets, which an infected person can spread when they talk, cough or sneeze, for example. The CDC adds that these droplets can land on hands and surfaces, where they might survive for some period of time and can potentially infect people. The CDC adds that "short-range" airborne spread of aerosolized particles is a "possibility," but stops short of definitively calling it a confirmed route of transmission.

The question of whether and to what extent these droplets might survive and spread through the air has been debated since early in the outbreak. The first strong scientific study backed by the U.S. government that showed the virus might spread through the air came on March 18.Researchers from the National Institutes of Health, CDC, UCLA and Princeton University examined how long Covid-19 survives in the air as well as on a variety of surfaces and compared it with SARS, the coronavirus that emerged in late 2002 and killed nearly 800 people.

They found that Covid-19 was detectable in aerosols for up to three hours, though it remained unclear whether the trace amounts of the virus found in the air were potent enough to infect someone and replicate. The results suggested "that people may acquire the virus through the air and after touching contaminated objects," Dr.Neeltje van Doremalen, a scientist from NIH and a lead researcher on the study, said in a statement at the time.

The Director-General of the World Health Organization Tedros Adhanom Ghebreyesus had said in a Feb. 11 press conference that "corona is airborne," but he quickly clarified his remarks, saying that he meant the virus can "spread via droplets or respiratory transmission."

It was not until March that the World Health Organization officially acknowledged that the virus-carrying droplets might be spreading through airborne particles in certain environments.

"When you do an aerosol-generating procedure like in a medical care facility, you have the possibility to what we call aerosolize these particles, which means they can stay in the air a little bit longer," Dr. MariaVanKerkhove, head of WHO's emerging diseases and zoonosis unit, said on March 16.

On July 6, a group of 239 scientists from 32 different countries published an open letter calling on the WHO and other health agencies to update their guidance to reflect the threat of airborne transmission of the coronavirus. The scientists said there was emerging evidence that indicated airborne transmission could present a serious risk.

"There is significant potential for inhalation exposure to viruses in microscopic respiratory droplets (microdroplets) at short to medium distances (up to several meters, or room scale), and we are advocating for the use of preventive measures to mitigate this route of airborne transmission," the scientists wrote in the paper.

That week, the WHO updated their official guidance to say that "short-range aerosol transmission, particularly in specific indoor locations, such as crowded and inadequately ventilated spaces over a prolonged period of time with infected persons cannot be ruled out." But like the CDC, the United Nations health agency stopped short of confirming that the virus spreads in such a way.

It was five months before that, on Feb. 7, that Trump told Woodward that the coronavirus was spreading widely through the air.

"You just breathe the air and that's how it's passed," he said, according to the tapes of the interview. "And so that's a very tricky one. That's a very delicate one. It's also more deadly than even your strenuous flus."

At around the same time, members of the Trump administration and the White House coronavirus task force told Americans that the general public did not need to buy masks, which appear to help prevent the virus-carrying droplets from spreading. Trump defended his decision to downplay the threat of the virus early in the outbreak.

"The fact is there has to be a calmness," he said Thursday. "You don't want me jumping up and down screaming there's going to be great death."

A beloved teacher dies from coronavirus – The New York Times

September 12, 2020

Then, working with a local nonprofit group, the school shifted its strategy. Instead of trying to pole vault its top students into top schools, it tried to focus on getting everyone into a degree program. With a dedicated college-advising office and recent graduates called bridge coaches, the on-time graduation rate is now about 70 percent. In 2019, 75 percent of graduates went directly to college.

We build up our students for four years, to get to the point where theyre confident and comfortable that they belong in college, Robert Schwarz, a vice principal, told The Times. That takes a lot of hand-holding.

Updated Sept. 11, 2020

The latest on how schools are reopening amid the pandemic.

Although the pandemic hit the school and its students hard, Richmond Hill maintained its counseling program. Even as the parents of some students died or lost their jobs, most seniors stayed on track. By early September, despite the pandemic, 70 percent of the graduating class was enrolled in college.

The intensive counseling the bridge coaches provided was the key factor in persuading those students to stick with their plans, said Paul Tough, a contributing writer at The Times Magazine who spent months looking into Richmond Hills strategy.

Now, similar counseling programs are under threat as districts and public college systems face budget cuts. Student support systems like counselors are often the first to go.

When you make those cuts, you inevitably have higher drop out rates, especially for low-income students, Paul said. That feels like the part of the crisis that hasnt happened yet, but everyone can see coming.

Read more: Predominantly white districts are more than three times as likely to be open for some in-person learning, compared with districts that enroll mostly students of color, according to an analysis by The Associated Press and Chalkbeat.

The Coronavirus Is Mutating, and Thats Fine (So Far) – The New York Times

September 12, 2020

I do not believe that the evolution of SARS-CoV-2 is whats driving the viruss continued spread. The coronavirus remains good at propagating itself because most of us still are susceptible to it; we are not immune, and it can still find new hosts to infect relatively easily.

In the same issue of Cell that published the Korber paper, the viral epidemiologist Nathan Grubaugh and colleagues argued that the increase in the frequency of G614 could be explained by chance and the epidemiology of the pandemic.

I agree.

In other words: The next time you compare different outbreaks and start wondering or worrying about the variations, assume first that those variations have to do with conditions on the ground, rather than anything about the virus itself, like a new mutation.

Consider, for example, the wave of SARS-CoV-2 infections that has hit Australia since June. While there has been a major outbreak in the state of Victoria (peaking at around 700 cases per day), the one in the state of New South Wales has been minor so far (with a daily case count usually around 10) yet both have been caused by the same variant of the coronavirus, the one with the D614G mutation.

The precise reasons for these differences are still being investigated, but one may be, simply, that because the outbreak hit Victoria first, the health authorities of New South Wales had more time to prepare.

Mortality rates, too, differ between locations, and in some places the virus may appear to kill more people. But again, these variations probably say less about the virus than about differences in how the disease is being treated, or where the virus has spread mostly among vulnerable populations, like people in nursing homes.

Whats more, even if the D614G mutation does increase the viruss infectivity in humans, that fact probably doesnt have any major implications for our prospects of developing an effective vaccine. The mutation does affect the spike protein, but not the part of it that the neutralizing antibodies of the human immune system target when the body defends itself against infection.

Coronavirus: the inside story | University of Minnesota – UMN News

September 12, 2020

New studies from the U of M College of Science and Engineering analyze how the coronavirus spreads indoors and in human lungs. This information may help businesses and schools control the spread of COVID-19, and help target medicines to virus particles in the lungs.

Using aerosol generation by healthyindividuals to mimic that from asymptomatic COVID-19 patients, mechanical engineering associate professor Jiarong Hong and assistant professor Suo Yang modeled virus transmission through aerosols ejected from an infected person via exhalation or speech. They found that the SARS CoV-2 virus hitches a ride on those aerosols and may land on nearby surfaces or be inhaled by another person.

The researchers numerically modeled how the simulated airborne virus flowed through an elevator, a classroom, and a supermarket and compared how the virus fared with different levels of ventilation and different spacing of room occupants.

They found that good indoor ventilation filters out some virus but may leave more viral particles on surfaces. In a classroom where an asymptomatic teacher talked for 50 minutes, only 10 percent of the aerosols were filtered out; the majority stuck to the walls.

The ventilation forms several circulation zones called vortexes, and the aerosols keep rotating in [them], Yang says. Because they are basically trapped, its very hard for them to reach the vent and actually go out.

The virus-bearing aerosols spread significantly less when the teacher stayed directly under an air vent. This insight could inform how classrooms are arranged and disinfected, and also help places like theaters and concert venues reopen with the proper precautions.

Reaching out

Yang and Hong have been working with the Minnesota Orchestra to measure aerosol concentrations and flow while instruments are played onstage at Orchestra Hall. Eventually, they hope to provide a plan to minimize the COVID-19 risk in Orchestra Hall.

The researchers recently joined an international work group of experts led by U of M professor Michael Osterholm, director of the Center for Infectious Disease Research and Policy, to learn how much SARS CoV-2 virus it takes to become infected and provide science-driven policy to mitigate the COVID-19 pandemic.

Read more.

Reaching in

Yang is also modeling aerosols to predict how the coronavirus travels inside the human respiratory system.

The key symptom of COVID-19 is the lung inflammation, he explains. Were trying to understand how the virus aerosol is transported and deposited in the lung. Where is the high concentration zone? Whats the pattern? Does it depend on other conditions?

By creating models of human lungs based on computed tomography (CT)scans from real COVID-19 patients, Yang hopes to inform the design of medical treatments, namely nasal sprays.His team has already begun running test simulations of aerosols in the back of the throat, nasal linings and trachea.

Then, Yang plans to map how medicine particles travel throughout those same systems in order to test the effectiveness of treatments and get the delivered to the right address in the lungs.

Once we optimize these options, we can give that information to the medicine companies, and they can create their products accordingly to most efficiently target the system," he added

Yang works with biomedical engineering professor David Odde, who earlier this year released a model of how the virus functions withinhuman cells. The two will combine their results into a comprehensive recommendation on treatment design.

8,800 migrant kids were kicked out of the US under coronavirus border restrictions – CNN

September 12, 2020

A court declaration Friday from US Border Patrol Deputy Chief Raul Ortiz revealed the number, which previously hadn't been released to the public.

Since the Trump administration invoked a public health law to implement new restrictions at the border on March 20, the agency has expelled more than 159,000 people, according to Ortiz. That figure, Ortiz says, included 8,800 children who were traveling alone and 7,600 family members.

The declaration was filed as part of the government's appeal of a recent court ruling over a controversial aspect of the coronavirus restrictions: the increasing use of hotels to detain migrant kids rather than licensed and monitored facilities.

But Ortiz and other US officials argue that doing so will put the public at risk, interfere with efforts by the Centers for Disease Control and Prevention to contain Covid-19 and increase the likelihood that US Customs and Border Protection agents and others caring for children in custody could contract coronavirus. They are asking California's 9th Circuit Court of Appeals to block Gee's order.

In his declaration on Friday, Ortiz stated that being forced to stop detaining migrant children in hotels would cause "three significant problems" for the government: crowding and an increased risk of Covid-19 exposure in Border Patrol facilities, an increased risk of Covid-19 exposure in Health and Human Services and Immigration and Customs Enforcement facilities and the straining of an "already overburdened system."

A Dating Guide For The Pandemic: From The First Hang To … Intimate Encounters : Goats and Soda – NPR

September 12, 2020

Each week, we answer "frequently asked questions" about life during the coronavirus crisis. If you have a question you'd like us to consider for a future post, email us at goatsandsoda@npr.org with the subject line: "Weekly Coronavirus Questions."

If you're wondering when it will be safe to date again or how to do it you're not alone.

Via social media and email, NPR readers have sent in questions about dating and relationships in the age of COVID-19. Some of the queries:

"Will I ever be able to impress women with my cooking skills again, or do we need to keep all dates outdoors?"

"Do we need to get tested before masks come off?"

"Are masks during sex really a thing?"

As one of our readers put it, it certainly would be easier if there were a dating app that assesses potential partners by their efforts to keep safe in the pandemic. Until that happens, we consulted with several health and relationships experts to figure out how to navigate intimacy while keeping COVID-19 at bay.

Their main takeaway? Just like before the pandemic, open and honest communication is key.

Having the "COVID talk"

When you first start dating someone new, you usually consider their hobbies, common interests and politics to figure out if you're a good match. Now, says sex and relationships writer Sophie St. Thomas, there's a new level of compatibility added in: you and your partner's approach to COVID-19 safety.

That means asking questions such as: If your job requires you to be around other people, what precautions do you take during and after interactions? Do you live with other people, and if so, how do you track each other's risk of exposure to the virus? Do you go to restaurants and other public spaces?

The experts we interviewed agreed that you should be asking potential partners these queries pretty early on, ideally before meeting in person. The answers help you gain a better sense of how much exposure this person has to other people and to environments that pose a risk of contracting the coronavirus. Basically, you're trying to assess your risk of getting sick if you start a relationship.

And even though it may feel uncomfortable to ask someone you just met about their daily whereabouts and activities, it's essential for everyone's health and well-being, says Dr. Joyce Sanchez, an infectious disease specialist at the Medical College of Wisconsin. You have to keep in mind that exposing yourself to a new partner doesn't just affect you, she adds the impact also extends to the people you live and work with as well as your community at large when you're out and about. Sanchez calls this your "bubble."

That bubble is constantly changing maybe one of your roommates just got back from a visit with family or you've been asked to start going to your workplace a few times a week. Sex educator and writer Gabrielle Alexa Noel says her girlfriend recently got a new roommate, which forced all three to have the "COVID talk" before choosing to share personal space. So you not only have to have great communication with a dating partner but with the people in your bubble, Sanchez says.

"Immediately, if someone is not eager to participate in a conversation like that, that would already give me pause," Noel says.

No matter how awkward or uncomfortable you might feel asking some of the questions, she says, if someone else is also taking their health seriously, that person should be eager to discuss safety and precautions with you as part of the bubble-merging process.

Dr. Abraar Karan of Harvard Medical School agrees he says you should approach this conversation the same way you would talk about sexually transmitted diseases before being intimate with someone for the first time: It's a matter-of-fact conversation about your health and that of your potential partners.

"Nothing can guarantee you are fully safe, but this is the best way to think about risk reduction," he says.

How should I transition from virtual and outdoor dates to indoor intimacy?

In-person connections are not off the table until the pandemic ends, says Dr. Dolores Albarracn, who teaches medicine and psychology at the University of Illinois at Urbana-Champaign.

Let's say you've met someone you like and have gone on several FaceTime or even picnic dates. But you'd like to take things to the next level and meet up indoors.

Sanchez recommends answering three main questions before making this leap:

Karan says COVID-19 case numbers and community spread within your county or neighborhood are a good benchmark to inform your decision to meet in-person indoors. If transmission rates are high, there's probably a higher risk that someone at a restaurant or cafe could have COVID-19 and potentially transmit the virus to you or your date so you may want to keep things online or outdoors for the time being.

If transmission rates in your community are low, you might feel safer venturing to an indoor location for dinner, Karan says.

Other factors to consider before choosing a date spot: Are all the tables at least 6 feet apart? Does the establishment require servers to wear masks? (More considerations on dining indoors here.)

If you're planning to take your dates into each other's homes and getting intimate, you should both be sure you don't have COVID-19, Albarracn says. She recommends getting tested and waiting to see if the result is negative or quarantining for two weeks without symptoms before close, mask-free proximity.

What about sex?

Speaking of protection, here's a question that probably never made it into Cosmopolitan magazine's dating advice columns: If you aren't willing or able to get tested or complete a two-week quarantine beforehand, are masks necessary during sexual encounters?

Canada's chief public health officer, Dr. Theresa Tham, became the latest among several health officials to suggest that when it comes to getting physical with a partner, people should wear masks and avoid kissing. New York City health officials also encouraged people to engage in positions facing away from one another to avoid the exchange of breathing particles. That's because a primary mode of transmission is mouth-to-mouth, so to speak particles breathed out by someone infected, then inhaled by someone else.

While Sanchez agrees that masks do make sexual activity somewhat safer in that they reduce the exchange of viral particles, she says it's hard to measure effectiveness.

"Unfortunately, the answer is we don't know how much the risk goes down when you wear a mask while having sex," Sanchez says. "Ultimately, you can't have sex 6 feet apart. So it's going to be a high-risk activity whether or not you wear the masks and avoid kissing."

Wouldn't it just be easier to hook up with my ex?

For some people, the pandemic has presented an additional layer of emotional confusion. Several readers wrote in with the conundrum: Is it worth the effort to try and meet someone new and figure out their pandemic philosophy or is it better to rekindle things with a former partner whose judgment on pandemic safety you already trust?

St. Thomas says it's perfectly normal to want to reach out to an ex during this time and check in in a dramatically changing world, it's OK to want to check in on people who have been an important part of your life. But that doesn't always mean it's a good idea to reignite a relationship that previously ended.

"It's so easy to [reach out], especially if you are socially isolated," she says. "[But] if someone is still a pain point for you, if it's something that is still fresh, I would caution against it."

Restarting things with an ex could potentially lead to mixed expectations about the relationship this time around or could negatively affect the progress you've both made since the breakup, St. Thomas says. Instead, she says, rely on your support group. Friends, family and a therapist are all good people to talk to about rekindling an old flame.

Relationships can be helpful

Although dating in the era of COVID-19 does present a series of risks, Karan says we have to assess it similarly to how we assess the risks we take when going to the grocery store or to a testing site. Meaningful emotional connections are still an essential part of everyday life and we should keep the rewards and benefits of dating in mind, just as we do with buying food or seeking medical care.

"I think we should not downplay the importance of human connection because relationships are what help us stay mentally sane through something like this," he says.

A University Had a Great Coronavirus Plan, but Students Partied On – The New York Times

September 12, 2020

At the University of Illinois at Urbana-Champaign, more than 40,000 students take tests twice a week for the coronavirus. They cannot enter campus buildings unless an app vouches that their test has come back negative. Everyone has to wear masks.

This is one of the most comprehensive plans by a major college to keep the virus under control. University scientists developed a quick, inexpensive saliva test. Other researchers put together a detailed computer model that suggested these measures would work, and that in-person instruction could go forward this fall.

But the predictive model included an oversight: It assumed that all of the students would do all of the things that they were told to.

Enough students continued to go to parties even after testing positive, showing how even the best thought-out plans to keep college education moving can fail when humans do not heed common sense or the commands from public health officials.

Last week, the university reported an unexpected upswing of coronavirus cases and imposed a lockdown. Students had to stay in their dorms or off-campus housing except for essential activities, which included going to class.

Randall Munroe, the creator of the popular internet comic strip XKCD, and a contributor to The Times, poked fun at the fact that two of the people who were key players in developing the models were physicists.

Cant understand why someone with a physics degree would be bad at judging how often college students get invited to parties, comments one of the XKCD characters.

Nigel Goldenfeld, one of the physicists who was the butt of the comic strip, replied in good humor. We enjoyed the joke, he said. But, he noted, it was not a completely accurate portrayal of what happened.

For one, while he and a fellow physicist, Sergei Maslov, had devoted effort to an epidemiological model for all of Illinois, the more detailed university simulation, modeling the movements of some 46,000 students, professors and others like servers in coffee shops and bars who interact with students, was the effort of a larger group and led by Dr. Goldenfeld and Ahmed E. Elbanna, a professor of civil and environmental engineering. (Its harder to make jokes about civil engineers.)

Second, they had indeed taken into account college partying and quite a bit of it more than 7,000 students partying three times a week in their model.

What the scientists had not taken into account was that some students would continue partying after they received a positive test result. It was willful noncompliance by a small group of people, Dr. Goldenfeld said.

Those were the key ingredients for a few people infecting many others. If you know you are positive, Dr. Elbanna said, and you go to a party, thats not just a bad act. Thats very, very dangerous.

Dr. Goldenfeld said the main purpose of the model was not to make precise predictions, but to help administrators make informed choices on what precautions made sense.

For example, the model showed that once-a-week screening, as university administrators originally planned, was too little, too slow. Students who were infected soon after a test cleared them would be infectious for days before the next test. The university increased the mandate to two tests a week, although now that schedule is only for undergraduate students.

Since the university clamped down last week, the number of new cases has dropped again, and the hope is that all students will now take the protocols more seriously.

Carl T. Bergstrom, a professor of biology at the University of Washington in Seattle and an infectious disease expert, said most of the other large state universities were opening and hoping for the best without doing any kind of serious testing or theyve switched to largely online education.

What the University of Illinois has tried to do is pretty unusual, Dr. Bergstrom said. Being able to have an in-person semester at a school of that size with that kind of social atmosphere is really a remarkable accomplishment and I think they have a reasonable chance of pulling it off, he said. If it if it doesnt work, they gave it a damn good try.

The positivity rate for the tests is currently about 1 percent. Its higher than we would like, but its coming down, said Rebecca Lee Smith, a professor of epidemiology at the University of Illinois. I am hopeful. Everything is going in the right direction.

Dr. Goldenfeld said the notoriety of recent days even had some upside: The XKCD zinging gave him street cred with his daughters, he said.
