Flying on a plane may present less risk for catching COVID-19 than going to the grocery store.
That's according to a new Harvard study.
Researchers say ventilation systems on planes, doubled with mask wearing, puts in-flight virus transmission at a lower risk than previously thought.
The study says that even though air on planes is recirculated, it goes through high-quality air filters first.
If you wear your mask the right way, virus droplets have a lower chance of spreading on a plane compared to other activities like grocery shopping or eating out.
However, the research did not cover the risk people face while at the airport.
