Even hot weather does not mean that the spread of Covid-19 virus has been reduced. This is according to experts from the United States.
In particular, several previous studies have given some hope that extreme heat could slow the spread of the virus. But epidemiologists say there is no evidence that viruses spread during the summer. Even if the temperature rises, that does not mean it will be good.
However, some preliminary studies suggest that temperature and humidity are associated with decreased or increased levels of Covid-19 virus.
An analysis by scientists at the Massachusetts Institute of Technology, published online on March 19, 2020, found that most cases of Covid-19 infection occur in areas with an average annual temperature between 2.78 degrees to 17.22 degrees Celsius. The total number of cases in the country with an average temperature above 17.78 degrees is only 6%.
A study published in March last year by Chinese researchers found that before the Chinese government began restricting cities with hot and humid climates, infection rates were lower.
Another publication by researchers from Spain and Finland found that 95% of global infections occur at temperatures between -2.22 degrees Celsius and 10 degrees Celsius in dry weather. Reduced new infections.
Elizabeth McGraw, director of the Center for Epidemiology at the University of Pennsylvania, said: "Drops containing the virus do not stay in the air for a long time, and warmer temperatures cause the virus to die faster than cold temperatures.
However, recent outbreaks of Covid-19 have also shown that hot and humid weather will not completely stop the infection. In fact, in Thailand or Cambodia, new cases have been found to increase, even in hot weather.
In this regard, Thomas Bollyky, director of the World Health Program from the Washington-based Council on Foreign Relations, said: As well as maintaining personal hygiene, everyone can ensure high security.
