COVID-19 'Super Spreaders' Quickly Fill Room With Virus — But Masks Help

But a severely infected person who's coughing frequently can fill a poorly ventilated room with as many as 7.4 million copies of the coronavirus for every cubic meter of air, according to researchers Michael Riediker and Dai-Hua Tsai, from the Swiss Centre for Occupational and Environmental Health in Winterthur.

Ashwini R. Sehgal, M.D., from Case Western Reserve University in Cleveland, and colleagues examined the feasibility of separate rooms for isolation and quarantine for housing units in the United States. Data on residential dwelling units and occupants were obtained from the 2017 American Housing Survey.

The researchers found that in 25.29 million dwellings, isolation or quarantine was impossible, because they lacked sufficient bedrooms, bathrooms, or both; this accounted for 20.8 percent of all residential units. This included about 30 percent of the 88.2 million units that housed more than one occupant. A total of about 81 million persons lived in units that were unsuitable for isolation or quarantine. The odds of occupying units unsuitable for isolation or quarantine were twofold to threefold higher for Native American and Hispanic persons relative to non-Hispanic White persons and 1.7-fold higher for Black and Asian persons.
