Quartz: “Americans who haven’t had covid-19 are now officially in the minority. A study published this week from the US Centers for Disease Control and Prevention (CDC) found that 58% of randomly selected blood samples from adults contained antibodies indicating that they had previously been infected with the virus; among children, that rate was 75%.

Stories abound of close calls, of situations where people are sure they could have (or should have) gotten sick, but somehow dodged infection. Not all the questions are answered yet, but the question of what distinguishes the never-covid cohort is a growing area of research even as the US moves “out of the full-blown” pandemic.

See also CNN – Most Americans have now had Covid-19 — but experts are predicting the next surge and also via CNN – Their virus symptoms were minor. Then they had long Covid.
