American scientists conducted a study on how climatic conditions affect the spread of coronavirus, reports RIA Novosti.
The researchers analyzed the daily data on the incidence of COVID-19 in the U.S. since the end of January to end of April and revealed their possible correlation with air temperature, rainfall, ultraviolet radiation.
As it turned out, the spread of the virus is really reduced with increasing temperature up to 11 degrees Celsius. A further increase of this indicator is not associated with reduced transmission of the virus. However, the researchers noted that the incidence of when the warm weather is lower than when cold. The highest increase in new cases was observed for negative values of the thermometer.
The air temperature is not the determining factor in the spread of coronavirus, which will continue and with more hot weather, the researchers note.
In addition, the high levels of UV radiation also contributes to the slowdown in the rate of infection, but the humidity and precipitation have no impact.
Scientists emphasize that based on these data, it is impossible to believe that the spread of the infection completely stopped in the summer months.
