Coronavirus SARS-CoV-2 spreads more indoors at low humidity.

The airborne transmission of the coronavirus SARS-CoV-2 via aerosol particles in indoor environment seems to be strongly influenced by relative humidity. This is the conclusion drawn by researchers from the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig and the CSIR National Physical Laboratory in New Delhi from the analysis of 10 most relevant international studies on the subject. Therefore, they recommend controlling the indoor air in addition to the usual measures such as social distancing and masks. A relative humidity of 40 to 60 percent could reduce the spread of the viruses and their absorption through the nasal mucous membrane. To contain the COVID-19 pandemic, it is therefore extremely important to implement standards for indoor air humidity in rooms with many people, such as hospitals, open-plan offices or public transport, writes the research team in the scientific journal Aerosol and Air Quality Research

And other findings dispute that:Temperature and Humidity Do Not Play a Major Role in Coronavirus Spread:

Research headed by The University of Texas at Austin is providing a little clarity on the role of weather in COVID-19 infection. The new study found that humidity and temperature do not play a major role in the spread of coronavirus.

A doctor's opinion:This winter, fight covid-19 with humidity:
