BOULDER, Colo. (CBS4) – A new study done by University of Colorado scientists confirms that singing without a mask on inside can spread COVID-19 particles easily. The study examined a March rehearsal in Washington.

The study, which has been peer reviewed and published in the journal Indoor Air, proves that aerosols projected by singing unmasked spreads the virus. Researchers studied a choir rehearsal in Skagit Valley, Washington, on March 10. One person with mild COVID-19 symptoms attended the 2-and-a-half hour indoor rehearsal. In the weeks that followed, nearly everyone who attended the practice — more than 50 people — contracted the disease. Two people ultimately died.

Those who attended had sanitized surfaces and avoided touching each other. That observation led scientists to conclude that particles spit into the air during the singing spread the disease.
