Infections May Be 10X Higher Than Confirmed Cases

The Washington Post reports:

Results from coronavirus antibody tests have started to trickle in, and they bolster the consensus among disease experts that the virus is significantly more lethal than seasonal flu and has seeded the most disruptive pandemic in the past century.

“I think it is the worst pandemic since 1918,” said Cecile Viboud, an epidemiologist at the National Institutes of Health’s Fogarty International Center, alluding to the “Great Influenza” pandemic that claimed an estimated 675,000 lives in the United States.

The new serological data, which is provisional, suggests that coronavirus infections greatly outnumber confirmed covid-19 cases, potentially by a factor of 10 or more. Many people experience mild symptoms or none at all, and never get the standard diagnostic test with a swab up the nose, so they’re missed in the official covid-19 case counts.
