As the BA.5 variant spreads, the risk of coronavirus reinfection grows

The size of that wave is unclear because most people are testing at home or not testing at all. The Centers for Disease Control and Prevention in the past week has reported a little more than 100,000 new cases a day on average. But infectious-disease experts know that wildly underestimates the true number, which may be as many as a million, said Eric Topol, a professor at Scripps Research who closely tracks pandemic trends.

Antibodies from vaccines and previous coronavirus infections offer limited protection against BA.5, leading Topol to call it “the worst version of the virus that we’ve seen.”

Other experts point out that, despite being hit by multiple rounds of ever-more-contagious omicron subvariants, the country has not yet seen a dramatic spike in hospitalizations. About 38,000 people were hospitalized nationally with covid as of Friday, according to data compiled by The Washington Post. That figure has been steadily rising since early March, but remains far below the record 162,000 patients hospitalized with covid in mid-January. The average daily death toll on Friday stood at 329 and has not changed significantly over the past two months.

There is widespread agreement among infectious-disease experts that this remains a dangerous virus that causes illnesses of unpredictable severity — and they say the country is not doing enough to limit transmission.

Restrictions and mandates are long gone. Air travel is nearly back to pre-pandemic levels. Political leaders aren’t talking about the virus — it’s virtually a nonissue on the campaign trail. Most people are done with masking, social distancing and the pandemic generally. They’re taking their chances with the virus.

“It’s the Wild West out there,” said Ziyad Al-Aly, an epidemiologist at Washington University in St. Louis. “There are no public health measures at all. We’re in a very peculiar spot, where the risk is vivid and it’s out there, but we’ve let our guard down and we’ve chosen, deliberately, to expose ourselves and make ourselves more vulnerable.”

Nearly one-third of the U.S. population lives in counties rated as having “high” transmission levels by the CDC. Cases are rising especially in the South and West.
