Coronavirus Today: The (potential) upside of Omicron – The San Diego Union-Tribune

Good evening. Im Karen Kaplan, and its Friday, Dec. 17. Heres the latest on whats happening with the coronavirus in California and beyond.

Lets be real: Almost everything we hear about the Omicron variant sounds scary. It seemed to come out of nowhere just a few weeks ago and already accounts for well over half of coronavirus cases in London. In South Africa, it reduced the effectiveness of the Pfizer-BioNTech vaccine to just 33%. In California, its infecting people who are not only fully vaccinated but got their booster shots too.

Even its name sounds a little too much like ominous.

But many scientists who are looking at the early Omicron data are feeling a little ... well ... hopeful.

Is this the end of the pandemic? asked one of them, University of Johannesburg coronavirus analyst Pieter Streicher.

Why does he think thats even a possibility? It boils down to two apparent attributes of the Omicron variant: It spreads like wildfire, and its less likely to make people severely ill.

As my colleague Melissa Healy explains, a strain that is both highly transmissible and much less virulent is exactly the type that becomes an endemic nuisance virus. It never goes away, but it doesnt do that much damage.

Four other coronaviruses ones that cause the common cold have already achieved this status. They make their hosts sick enough to cough or sneeze out infectious particles but not so sick they stay home and miss the chance to spread those germs to others. Each infection leaves some immunity in its wake, but most people remain susceptible most of the time. The virus and humanity reach a stalemate.

Thats what we all hope, said Dr. Stanley Perlman, a University of Iowa virologist who has studied coronaviruses for decades.

The preliminary findings about Omicron are based on population studies from South Africa and experiments conducted in labs. Observations from countries around the world back them up, but it will be another week or so before theres enough hard data to be convincing.

Thus far, COVID-19 death rates across South Africa have dropped considerably despite the Omicron wave. If that continues to be the case for the next two or three weeks and there is no massive surge in hospitalizations, it may well mark turning point in [the] pandemic, according to Dr. Shabir Madhi, an infectious-disease expert at the University of the Witwatersrand.

Some scientists insist that kind of thinking is premature. Omicrons behavior in the U.S. may be different than its behavior in South Africa, since the population there is much younger, among other differences.

Plus, Omicrons propensity to spread may negate its lighter touch: If the variant is half as likely to make people severely ill but twice as transmissible, itll be a wash.

And then theres the ever-present possibility that a new mutation will come along and change the game again. The coronavirus could become easier to contain or it could make things worse.

William Hanage, an epidemiologist at Harvards School of Public Health, is among those who arent ready to breathe a sigh of relief.

Only a fool would bet against Mother Nature, he said.

Someday, the pandemic will be over. But for many of those who lost loved ones, life will never return to normal. Its not just the emotional toll of knowing that parents, spouses or other cherished people are gone for good. Its the way their absence affects the trajectory of their lives.

Janelly, Melanie, Leanna and Sergio Ayala all of them 10 or younger are in this unfortunate category. Their father, 37-year-old Sergio Ayala, died of COVID-19 in January. In addition to being a doting parent, he was a breadwinner with a good job as a field supervisor at his brother-in-laws pest control company. He was also taking steps to become a barber and own his own business.

Once that dream was fulfilled, he had planned to start college savings funds for all four of his children. His partner, Lizeth Sanchez, was going to go back to school and study sociology. Instead, she will stick with her job at a medical device manufacturing company. She worries that shell only be able to send one of their children to college.

The family Sergio Ayala left behind is hardly alone, my colleague Alejandra Reyes-Velarde reports. In California, COVID-19s victims include a disproportionate share of younger Latinos people whose families relied on them for financial support.

There are a variety of reasons why COVID-19 has been particularly unkind to this demographic. To name a few: Theyre more likely to work in essential jobs that increase their exposure to the coronavirus; they have higher rates of conditions like obesity and hypertension that are associated with severe COVID-19; and they are more likely to live in crowded and multigenerational homes, increasing the risk that if one family member catches the coronavirus, others will too.

When you add it all up, Latinos in California have lost roughly 370,000 years of potential life due to COVID-19, according to UCLA biostatistics researcher Jay Xu.

Some of those years would have been spent making families more financially secure and creating opportunities for upward mobility. Instead, those left behind will be struggling just to stay where they are and hoping they dont fall further behind.

Prior to the pandemic, about 38% of Latinos in California were in the middle class, and more than half were in the lowest income bracket, according to a report from the California Latino Economic Institute. Thanks to the pandemic, many of those in the first category have slipped into the second.

A survey by the Pew Research Center found that, a year into the pandemic, 44% of Americans said either they or someone in their household had lost a job or taken a pay cut because of the pandemic. Among Latinos, that figure was about 60%.

When Latinos struggle, the whole state struggles.

If Latinos are left behind, thats going to have a significant impact on Californias overall economy, said Mindy Romero, a political sociologist at USC. You cant leave behind your most populous community.

Sanchez will do the best she can for her children, without Ayalas help. But deaths like his have the potential to widen the class divide in the decades to come.

Winter is coming.

That Game of Thrones warning also applies to the real world, where the rapidly spreading Omicron variant and the destructive Delta variant are threatening to overwhelm hospitals in the coming weeks.

Californias COVID-19 forecasting models show that a winter surge could be worse than this summers Delta wave, which stretched hospitals to their limits in much of the state.

We will, in fact, see a pretty significant surge in our cases, said Los Angeles County Public Health Director Barbara Ferrer.

Thats already happening in Riverside County, which hasnt had a break since patients sickened by Delta began filling hospitals months ago. Its been so bad that patients have had to wait up to five hours just to be transferred from an ambulance gurney to a bed in the ER, said Bruce Barton, director of emergency management there.

Colder weather and holiday gatherings could make the situation even worse. And if patients go to hospitals, theyre likely to find them short-staffed because exhausted employees have left the industry.

The combination of Delta and Omicron is a perfect storm for overwhelming our hospital system that is already strained, said Dr. Regina Chinsio-Kwong, a deputy health officer for Orange County.

The problem isnt limited to California. Omicron cases in the U.S. are doubling about every two days, said Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention. The CDC says there could be more than 1 million new coronavirus cases next week; around Halloween, there were 500,000 in a week.

President Biden didnt mince words when he described the threat on Thursday: For [the] unvaccinated, we are looking at a winter of severe illness and death, he said. That was followed by the usual pitch to protect yourself and others by getting vaccinated and boosted.

Infections are also spiraling in the United Kingdom, hitting record highs. That prompted France to tighten entry rules for travelers from the U.K. In addition, Greece and Italy tightened entry requirements for all visitors this week while Portugal extended stricter border controls that were already in effect.

In the Netherlands, where a partial lockdown has been in place since November, the government ordered elementary schools to begin Christmas break a week early in hopes of heading off an Omicron surge. Dutch leaders also followed Britains lead by accelerating their booster shot campaign.

Back in the U.S., the CDC is easing up on schools by backing test-to-stay policies that let students remain in classrooms after theyve been exposed to an infected person but only if the exposed students are asymptomatic and test negative for a coronavirus infection. The CDC says the change will minimize disruptions for students without putting them at increased risk.

Previously, the guidance was for students to quarantine at home for 10 days if they came in close contact with an infected person. As of Friday, both policies are considered viable options. (Some schools may want to continue with quarantines because the monitoring needed for test-to-stay can be costly.)

The CDC said its decision was influenced by the experience of school districts in Chicago and L.A. County, which kept case rates in check when they implemented test-to-stay policies. L.A. Unified was not one of them more than 2,000 LAUSD students enter quarantine in a typical week but the nations second-largest school district was already planning to shift to a policy like the one endorsed by the CDC.

The CDC also made a change to its COVID-19 vaccine recommendations, saying Americans would be better off with either the Pfizer-BioNTech or Moderna shots than with the one from Johnson & Johnson. The updated advice was based on a reassessment of the risk of developing rare but serious blood clots after getting the J&J shot, as well as a recognition that the other vaccines have proved more effective.

Until now, all three vaccines were treated as if they were equally good. The fact that the J&J offering came in a single dose was expected to be an advantage, since it offered a simpler path to full immunization. But it hasnt proven nearly as popular as its two-dose counterparts: Of the more than 200 million Americans who are fully vaccinated, only about 16 million got the J&J shot.

Although its not preferred, the J&J vaccine will remain an option for Americans who arent comfortable with the Pfizer and Moderna mRNA vaccines.

And speaking of the Pfizer vaccine, a very-low-dose version being tested in 2- to 4-year-olds did not prompt a strong enough immune response after two shots, the company said. The company will now test three doses to see if protection improves.

The dosage being tried is one-tenth the adult dose, and Pfizer said it had no plans right now to increase it. The two-dose version for 5- to 11-year-olds is one-third the adult dose.

Its not clear how long this setback may delay a COVID-19 vaccine for the youngest children. If the three-dose series is shown to work in a clinical trial, Pfizer and BioNTech said theyd seek emergency use authorization sometime before the end of June 2022.

This picture was taken just over a year ago as the biggest immunization drive in American history got underway. Its from a Pfizer manufacturing plant in Michigan, and the green forklift speeding by is moving boxes of COVID-19 vaccine.

After losing 300,000 Americans in less than a year, health officials were thrilled to see injections going into arms. It seemed like nothing short of a miracle that the shots along with similar ones produced by Moderna were developed in a matter of months and were at least 94% effective in clinical trials.

A year later, the U.S. death toll from COVID-19 stands above 800,000 despite the widespread availability of multiple vaccines. People who are fully vaccinated are 14 times less likely to die of the disease than people who are unvaccinated, according to the CDC. But numbers like that have a hard time breaking through the wall of misinformation that has scared millions of people away.

Dr. Francis Collins, director of the National Institutes of Health, said he and other experts underestimated how the spread of misinformation could hobble the astounding achievement of the vaccines.
