Scientists studying tiny exhaled particles that could transmit the coronavirus say a Centers for Disease Control and Prevention decision to drop warnings against choral singing is dangerous, risking more 'super spreading events' such as a Washington state choir practice linked to two deaths.
Scientists studying tiny exhaled particles that could transmit the coronavirus say a Centers for Disease Control and Prevention decision to drop warnings against choral singing is dangerous, risking more “super-spreading events” such as aThe researchers say that the coronavirus can spread in respiratory aerosols, which may linger in the air for an hour or more, floating farther than the six feet commonly prescribed for social distancing.
The novel coronavirus surfaced only a little more than five months ago in Wuhan, China, therefore, some degree of uncertainty about the pathogen is to be expected, as scientists study its characteristics. But the conflicting advice from domestic and international health agencies is striking, creating confusion as the U.S. death toll continues rising above 100,000.
Dr. Benedetta Allegranzi, WHO technical lead of infection prevention and control, said in an email Sunday that despite theories based on lab simulations, “there is no evidence of transmission of the virus as an airborne pathogen.” Since the Los Angeles Times reported on the outbreak from the Skagit Valley Chorale’s March 10 rehearsal, other super-spreading events have come to light. Four people died of COVID-19 after a choir performance in Amsterdam on March 8, and two members of a church congregation in Calgary, Alberta, died of the disease after a March 15 gathering that included singing.
Members of the Skagit Valley choir believed that no one present had symptoms of illness, and they used hand sanitizer, brought their own music scores and refrained from hugs and handshakes. But the study conducted by a research team found that one singer did have symptoms and later tested positive for COVID-19.
