CDC revises guidance, says COVID-19 can spread through virus lingering in air

The CDC guidance comes weeks after the agency published – and then took down – a similar warning, sparking debate over how the virus spreads. In Monday's guidance, CDC said there was evidence that people with COVID-19 possibly infected others who were more than 6 feet away, within enclosed spaces with poor ventilation. Under such circumstances, CDC said scientists believe the amount of infectious smaller droplet and particles, or aerosols, produced by the people with COVID-19 become concentrated enough to spread the virus.
