WASHINGTON — In guidance updated on Monday afternoon, the Centers for Disease Control and Prevention finally acknowledged that “airborne transmission” of “small droplets” can be responsible for coronavirus infections, including at a distance of more than 6 feet away, in some

The updated guidance reflects a continuing battle between public health officials and the Trump administration over how to accurately describe risks associated with different environments.

Although scientists have long known that the coronavirus is spread through air — as opposed to the unlikely form of transmission from touching contaminated surfaces — the debate over whether it is “airborne” has to do with just how long viral particles linger in the air and what size those particles must be to remain infectious.

“There is evidence that under certain conditions, people with COVID-19 seem to have infected others who were more than 6 feet away. These transmissions occurred within enclosed spaces that had inadequate ventilation. Sometimes the infected person was breathing heavily, for example while singing or exercising,” the updated guidance says.

The new guidance appears to caution against activities such as political rallies and sports events, where many people may be crowded together indoors. The CDC now says that, in those enclosed, poorly ventilated spaces, “the amount of infectious smaller droplet and particles produced by the people with COVID-19 became concentrated enough to spread the virus to other people. The people who were infected were in the same space during the same time or shortly after the person with COVID-19 had
