Scientists are realizing more ways that coronavirus is being spread. It isn’t just through close contact as many have first proclaimed. The virus can float through the air and be inhaled by someone, even if they’re diligently practicing social distancing.
During these summer months, as more people head back to work, and doing more group activities, the airborne virus is a concern for many. So scientists have turned their attention to air conditioning.
Why air conditioning, you may ask?
According to infectious disease expert, Ed Nardell at the Harvard T.H. Chan School of Public Health, indoor AC units can spread the virus. The units create air currents that can blow the virus around a room. He said that problem was clear in the case of one restaurant in Wuhan, China, where researchers studied why so many people eating there became sick.

What do we know for sure?
Cases of COVID-19 have risen fast “in some of the hottest and stickiest parts of the country,” according to USA Today.
Engineers and ventilation experts told USA Today this might because residents avoid the heat by heading indoors, which leads them to areas with air conditioning and ventilation systems.
Those systems might spread COVID-19 farther than fresh air.
