“At the moment, the mayor has no other symptoms, but is already in isolation and will cancel all public events for the rest of the week,” the statement said. “He will also immediately start taking the antiviral drugs that are offered free of charge to New Yorkers and encourage all New Yorkers who are eligible for these drugs to take them as well.” “As long as he is isolated, he will continue to serve New Yorkers by working remotely,” Levy added. Adams has appeared at several public events in New York this week. On April 2, he attended the Gridiron Club dinner in Washington, DC. At least 67 people who attended the dinner tested positive for Covid-19 on Saturday, according to a letter from the club to its members. But it is not clear where the mayor got the virus. Many members of President Joe Biden’s cabinet and various lawmakers are among those who were positive after attending the Gridiron dinner, CNN reported earlier, including Attorney General Merrick Garland and House Speaker Nancy Pelosi. Biden did not attend. The U.S. Centers for Disease Control and Prevention said in December that the greatest spread of Covid-19 “occurs early in the course of the disease, generally 1-2 days before the onset of symptoms and 2-3 days after.” CNN’s Sonia Moghe and Athena Jones contributed to this report.
