Public health officials studying the Covid-19 outbreak among members of a Washington choir found numerous ways the virus could have spread, according to a report published by the Centers for Disease Control and Prevention. From a report: Authorities interviewed all 122 members of the Skagit Valley Chorale, which met every Tuesday for 2.5 hours before the outbreak. They focused on two rehearsals held March 3 and March 10 in Mount Vernon, Washington. The report said 53 people were sickened and two died — and all but one attended both rehearsals. The report said Thirty-three cases were confirmed, the report said, and 20 people had probable infections. There were 61 people at the March 10 rehearsal, including one member who reported having had cold-like symptoms. That person tested positive for Covid-19 and was the first case identified by health authorities, according to the report. That person attended both practices but didn’t start showing symptoms until March 7.
