Activity of the corona virus in different climatic conditions


While combating the corona virus, there is a discussion about the climatic conditions in which the virus is active and therefore contagious.
Numerous studies have shown that the coronavirus survives longer when the temperatures are low and the air humidity is low. At high temperatures and a humidity of 40 - 60% rH however, the lifespan of the virus is reduced.

Especially indoors, the air humidity is very low during the heating period - sometimes below 20% rH. Ventilation does not help, since cold outside air contains little absolute humidity. Living, working and commercial rooms should be humidified.
Like dust, germs, bacteria and viruses are bound at high air humidity, they become heavier and sink to the ground. They are simply not as floating in high humidity as in dry air. In addition, healthy humidity protects the mucous membranes in the nose and throat from drying out. Mucous membranes are the body's protective shield against germs, bacteria and viruses. This means that higher air humidity significantly reduces the susceptibility to colds.


ZDF deals with the topic in an interesting report that explains the connection between climatic conditions and virus activity.
