CDC Revises Guidance, Says COVID-19 Can Spread Through Virus Lingering in Air | Top News

(Reuters) – U.S. Centers for Disease Control and Prevention (CDC) on Monday said COVID-19 can spread through virus lingering in the air, sometimes for hours, acknowledging concerns widely voiced by public health experts about airborne transmission of the virus.

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.

The CDC has long warned of transmission through small droplets that shoot through the air and generally fall to the ground, which resulted in the six-feet social distancing

By the third week of March, Vanier had tested negative for Sars-CoV-2 – the virus that causes Covid-19. But although the virus had left her body, this would prove to be just the beginning of her problems. In May, she noticed from her Fitbit that her heart rate appeared to be highly abnormal. When cardiologists conducted a nuclear stress test – a diagnostic tool that measures the blood flow to the heart – it
