Key factors for the transmission of the SARS-CoV-2 coronavirus may be the rate of evaporation of moisture in the air and the strength of the wind.
As reported in a EurekAlert! Press release, the corresponding study was conducted by specialists from the American Institute of Physics. It turned out that high temperatures and low air humidity reduce the viability of the virus.
“We found that high temperatures and low relative humidity result in a high evaporation rate from saliva-contaminated droplets, significantly reducing the viability of the virus,” said co-author Talib Dbouk.
Furthermore, the researchers observed that the travel distance and concentration of a droplet cloud remained significant even at high temperatures and high relative humidity.
Wind speed is another main condition that affects possible changes in social distancing rules.
These findings help explain why the pandemic intensified during July in several densely populated cities around the world, where high temperatures and high relative humidity were observed, scientists say.
They also warned of the possibility of a second wave of the pandemic in the coming fall and winter seasons, when low temperatures and high wind speeds would increase survival and airborne transmission of the virus.
As reported by OBOZREVATEL, American scientists have demonstrated transmission of the coronavirus by aerosol. The most dangerous were the smallest particles that are produced when breathing, talking and coughing.
