US health officials believe 20M Americans have had virus

WASHINGTON (AP) — U.S. officials believe as many as 20 million Americans have contracted the coronavirus, suggesting millions had the virus and never knew it.

That’s nearly 10 times as many infections as the 2.3 million cases that have been confirmed and comes as the Trump administration works to tamp down nationwide concern about the COVID-19 pandemic as about a dozen states are seeing worrisome increases in cases.

Since mid-May, when the government began stressing the need to get the economy moving again, the panel’s public health experts have been far less visible than in the pandemic's early weeks.

Twenty million infections would mean about 6% of the nation’s 331 million people have been infected, leaving a majority of the population still susceptible to the virus. Previously, officials at the Centers for Disease Control and Prevention and the nation’s top infectious-disease expert, Dr. Anthony Fauci, have said that as many as 25% of infected people might not have symptoms.

The new estimate is based on CDC studies of blood samples collected nationwide. Many infections were not caught in early testing, when supplies were limited and federal officials prioritized testing for those with symptoms.

Administration officials are pointing to the new data to allay public anxieties, claiming that while there have been significant spikes, they have the outbreaks well in hand.
