How weather plays a role to spread Covid-19

A full year has completed since the Covid-19 pandemic occurred, but there is not enough research to understand how SARS-CoV-2 changes in a climate-changing environment. Because of its mutation ability, it needs to be studied. However, scientists are working to determine the impact of climate on it. Detailed information Since the virus emerged from Wuhan; some people believe that the virus infection may have a certain seasonality.

Regarding other influenza viruses, medical experts speculate that the infection rate will increase in autumn and winter. In temperate climates and summer, infections are less frequent. 

The difference in infection is based on geographic location, altitude, and annual changes. The impact of climate Scientists can say that the population's immune status is much more important than the climate in determining the trend of infection transmission. Seasonality is becoming less and less important.

The research team checked three parameters, such as ultraviolet radiation, temperature and humidity.

Ultraviolet radiation : Ultraviolet rays can affect the survival of SARS-Cov-2 in vitro. Some research have shown that there is a negative correlation between ultraviolet radiation and infection rates. 

Temperature and humidity : Environmental conditions where the temperature is below five degrees and low humidity will positively affect the spread of the virus.The spread of the virus to the children and elderly with pre-existing diseases increases the risk of respiratory and cardiovascular diseases. 

Air pollution : Prolonged exposure to high levels of air pollution will increase Covid-19 infections. PM2.5, ozone and nitric oxide. 

This can cause problems with the immune system and increase the possibility of complications. And need to be hospitalized. The spread of Covid-19 may be affected by government interventions such as quarantine, travel restrictions and wearing masks. Weather conditions or air quality should not be a factor for the government to relax and spread Covid-19 infection.
