Scientists to Choirs: Group Singing Can Spread the Coronavirus, Despite What CDC May Say


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. The 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. They say that choir members are particularly vulnerable to infection from airborne particles, because they exhale and inhale deeply to sing, often at close quarters in poorly ventilated rooms.

The CDC generally dismisses the potential for airborne transmission beyond six feet, although a study it published recently said the “act of singing” likely contributed to 53 of 61 people who attended a choir rehearsal in March getting sick, two of whom died of COVID-19. Since that incident north of Seattle, reports have surfaced of other outbreaks after choir performances, including one in Amsterdam that claimed four lives.

Without notice on its website May 23, the CDC altered guidance for reopening houses of worship, deleting a warning posted the previous day that said the act of singing may contribute to the transmission of COVID-19. The warning disappeared as President Trump deemed religious institutions essential, calling on governors to reopen them from coronavirus lockdowns.

“Removing that guidance is extremely dangerous and irresponsible,” said Jose Jimenez, a University of Colorado chemistry professor who studies aerosols, adding it “will put people at risk of additional super-spreading events and slow down the containment of the epidemic.”

Donald Milton, a University of Maryland bio-aerosol researcher, spoke during a May 5 webinar sponsored by multiple national music organizations — and since watched by more than 100,000 people — that stunned the choir world. Experts advised choirs and performing arts groups not to gather again to sing in person until a vaccine or treatment for COVID-19 becomes widely available, even if that takes two years or more.

“The CDC’s earlier recommendations were spot on, and I’m sorry to see that they’ve changed them,” Milton said in an interview. “This is very hazardous, and we really need to not be getting together to sing.” Read More
I posted a link to this article in my article, "Let's Get Creative!" which I posted yesterday. I reposting a link to the article for wider readership. Churches deserve to have reliable information about the transmission of COVID-19 to help them in making decisions about regathering. It is reprehensible for the White House to modify CDC recommendations to serve its political agenda of the moment. The recommendations that the White House has authorized, while they may appeal to church leaders who downplay the seriousness of the COVID-19 pandemic and the need for layers of precautionary measures to suppress or mitigate the spread of the virus, can do a great deal of damage to the witness of many local churches across the United States. They may chose to regather without taking necessary precautions, become the nexus of a new cluster of COVID-19 cases and deaths, and irreparably damage not only their public image in their respective communities but also the public of other community churches.
