How coronavirus spread from one member to 87% of the singers at a Washington choir practice
(CNN)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.
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.
