Oct. 5 (UPI) — The U.S. Centers for Disease Control and Prevention posted a long-awaited update on the agency’s COVID-19 website Monday clarifying that the disease can sometimes be spread through airborne transmission and can travel more than 6 feet in unventilated spaces.
The agency said evidence shows the coronavirus can spread from particles that linger in the air even after an infected person has left, like the way tuberculosis, measles, and chicken pox are spread.
“The virus that causes COVID-19 appears to spread more efficiently than influenza but not as efficiently as measles, which is among the most contagious viruses known to affect people,” the website said. “People who are infected but do not show symptoms can also spread the virus to others.”
The update said that under certain conditions, people with COVID-19 seem to have infected others who were more than 6 feet away in poorly ventilated spaces.
