Heat and moisture evaporation: how weather affects the survivability of coronavirus
SARS-CoV-2 is found on various surfaces - from handrails to clothing. Does the heat stop the spread of the disease? Yellmed.
Experts analyzed the drying rate of viral particles under various weather conditions. The study showed: SARS-CoV-2 remains on the surface in a humid environment five times longer in comparison with its survival in dry areas.
Experts emphasize: people need to be careful in the summer, when the weather can quickly go bad. At the same time, an increase in temperature contributes to the death of the virus: in the heat, it quickly leaves the surfaces. However, ultraviolet rays are not capable of completely destroying SARS-CoV-2.

“We saw a correlation between the weather outside and the growth rate of COVID-19,” the authors of the study note. “This partly explains the slow or fast growth of infection in a particular city."
According to experts' recommendations, cotton and wood products should be cleaned more often than glass and steel surfaces, since drops evaporate very quickly on them.
