Coronavirus live updates: South Korea new cases most since March; Abbott wins U.S. authorization for $5 test

South Korea reported 441 new coronavirus cases, the highest since March, as the country’s health ministry flagged risks from new clusters at call centers and logistics warehouses.

Turmoil over the recent move by the Centers for Disease Control and Prevention to revise its testing guidance for people without symptoms escalated Wednesday as the governors of New York and California both said they would not be following the new guidance. The CDC now says people who came into contact with someone who tested positive for Covid-19 “do not necessarily need a test,” a declaration that New York Gov. Andrew Cuomo criticized as “political propaganda.” Assistant Secretary for Health Adm. Brett Giroir, who leads the Trump administration’s testing effort, denied that there was any push from the Trump administration to make the change.
