BA.5 Covid Subvariant Four Times More Resistant To Vaccines
BA.5 is the most prevalent strain of covid in the U.S., and it's now deemed "hypercontagious" since it's shown to be even more resistant to covid shots. As reports cover ongoing infections, CBS News notes over half of Americans now live in a place where masking against covid is recommended.

The Omicron Subvariant Dominating U.S. COVID-19 Cases Is More Vaccine-Resistant
The BA.5 omicron subvariant, which is now the most prevalent coronavirus strain in the United States, is four times more resistant to COVID-19 vaccines, according to a new study. The strain, which is considered "hypercontagious," according to the Mayo Clinic, is more defiant against messenger RNA vaccines, which include Pfizer and Moderna. (Archie, 7/15)

COVID Variants Mean Ventilation Is More Important Than Ever. So What Does ‘Good’ Air Flow Look Like?
As coronavirus variants like BA.5 and BA.2.75 become more prevalent and more transmissible, experts are repeatedly pointing to a transmission reduction strategy that’s worked since the beginning of the pandemic — air ventilation, especially indoors. “We don’t know what variants we’re dealing with in the future,” said Stanford University infectious disease specialist Dr. Abraar Karan, “but transmission is always the same.” (Echeverria, 7/14)

Bay Area Wastewater Surveys Suggest COVID Surge Could Be Biggest Yet
Surveys of coronavirus levels in Bay Area wastewater suggest that the region’s relentless spring COVID surge probably rivals the winter omicron wave in terms of the number of people currently infected — in fact, this surge may be the largest yet in some places. But capturing the scale of disease, and conveying to the public the relative risk of getting sick, is becoming increasingly tricky, health experts say. (Allday, 7/14)

The BA.5 Wave Is What COVID Normal Looks Like
Coronavirus test-positivity trends, for instance, look quite bad. A rate below 5 percent might have once indicated a not-too-bad level of infection, but “I wake up every morning and look … and it’s 20 percent again,” says Pavitra Roychoudhury, a viral genomicist at the University of Washington who’s tracking SARS-CoV-2 cases in her community. “The last time we were below 10 percent was the first week of April.” It’s not clear, Roychoudhury told me, when the next downturn might be.
