The United States is in the midst of another coronavirus surge, this time thanks to the omicron subvariant BA.5. Scientists warn that the new subvariant appears to be the virus’s most transmissible version to date, and it is reinfecting people who have already dealt with previous variants once or twice, sometimes as recently as a few weeks ago.
The small percentage of people who avoided Covid-19 for 2 1/2 years are also finding out BA.5 has ways of slipping past their defences. Even President Joe Biden, who had managed to avoid an infection, tested positive on Thursday. Like many Americans, Biden and his aides had let their guard down, loosening stringent Covid-19 precautions previously employed at the White House.
Everyone just wants to get back to normal, although polls show that few Americans are sure what living with Covid-19 should really look like. Most cities are unlikely to bring back mask mandates or other protective measures used earlier in the pandemic, or even in the original omicron surge.
“We’ve had a shift in our baseline,” said Michael Osterholm, a public health researcher and director of the Center for Infectious Disease Research and Policy at the University of Minnesota. Hospitalisations have roughly doubled since May and more than 400 Americans are dying everyday, but these numbers are significantly lower than the peak of the winter omicron wave.
“Earlier in the pandemic, we would never have accepted these numbers,” Osterholm said.
There’s also the potential for developing symptoms of long Covid-19, which researchers are trying to fully understand. Still, experts are weighing in on those concerns.
“We can live our lives knowing very well that this risk exists,” said Dien Ho, a bioethicist at Massachusetts College of Pharmacy and Health Sciences.
The question is: Which public health measures does the nation need to prioritise. And what can you do individually to lower your risk of exposure, slow the relentless cycle of new variants and minimise the disruption to daily life? Here are five steps to take, if you haven’t already.
1. Max out your vaccines and boosters.
If you have not received your booster — or any shots at all — experts say that the current surge is a good reason to schedule an appointment now. Vaccines provide excellent protection against serious illness and booster shots can amplify those benefits. But fewer than half of Americans have received boosters, and less than one-third of adults who are eligible for their second booster (or fourth shot) — those who are immunocompromised or older than 50 — have received it.
The Centers for Disease Control and Prevention’s use of the term “fully vaccinated” to describe the first two doses of vaccines early in the pandemic has not helped. Although the agency has since switched to saying that people should be “up to date” with all their shots, the early use of “fully vaccinated” has unfortunately stuck.
“A lot of people have said, ‘I’ve had my two shots and I’m done,’” Osterholm said.
2. Find your new community Covid-19 indicators.
You should keep an eye on Covid-19 statistics to figure out your own risk and decide when to add more levels of protection. For a majority of the pandemic, the CDC’s colour-coded map of community-level risk was a good indicator of cases and transmission rates. But the agency recently changed the way it calculates these risk levels to put more emphasis on local hospitalisation rates.
Case numbers no longer closely track with hospitalisations because of the mix of natural or vaccine immunity, home testing and treatments that are available, blurring real-time tracking of the virus. Instead, experts recommend using other ways to stay informed of your community’s Covid-19 risks: Check local news and tap into your social networks.
Talk to your family and friends as well as other members of your community to find out whether they’ve had Covid-19 recently or know anybody who has or recently had Covid-19, said Ajay Sethi, a public health researcher at the University of Wisconsin-Madison. Because you’re more likely to interact with people in your network, you may get a better sense of incidence in your community and what your own risk of getting sick may be.
3. Mask up, and not just indoors.
Wear good-quality masks in public places where you need to protect yourself, whether you have been infected with Covid-19 or not. Each infection may still bring the risk of developing debilitating long Covid-19 symptoms, said Caitlin Rivers, a public health researcher at the Johns Hopkins Center for Health Security.
“For me, the thought process hasn’t changed too much,” Rivers said. “I continue to wear a mask whenever I’m indoors and try to move as many activities as I can outdoors.”
Other experts agree that if you want to go maskless, outdoor air will be considerably safer than indoor spaces. But even outdoors, the closer people are together, the higher the risk of catching the virus.
4. Keep rapid tests on hand — and use them.
