According to this release by NPR, coronavirus infections in the United States are far higher than what has been confirmed, although the number of Americans who have been exposed is far below what is required for widespread immunity. The CDC estimated the number of infections is about 10 times higher than the confirmed cases, based on blood samples analyzed for antibodies in 10 regions. Those regions included the New York City metropolitan area, parts of Washington state, Utah, south Florida and Missouri.

Experts say at least 50%-60% of exposure is required for herd immunity, where prevalence of exposure, and/or a vaccine, drastically reduces transmission of the virus. The CDC is careful to point out, however, that it doesn’t know if the presence of antibodies prevents reinfection by the coronavirus.
