Do viruses die in the cold?
Beuther: It turns out that the cold air actually allows the virus to survive longer. And those particles that blast out when you sneeze kind of dry up and get smaller in the cold, so they can disperse much farther. So the virus lives longer, it disperses better, it’s transmitted better when it’s cold outside.
Why are viruses more common in winter?
The virus lives longer indoors in winter, because the air is less humid than outside. While it’s alive and in the air, it’s easy for people to inhale it, or for it to land on the eyes, nose, or mouth. We spend more time indoors and have closer contact with each other, which makes it easier for the virus to spread.
