Question

Why can virus be spread easily in the winter?

?

Answer 1

Many things play a role in making the flu more common in the 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.

Answer 2

Idk but maybe is because the weather of the summer is hot so the virus cant live too long. Oppositely, the temperature of the winter is low and give the virus opportunities to breed
