According to Ukrinform, this is stated in an article published on the portal Frontiers in Public Health.
For example, researchers in Beirut have looked at known seasonal viruses such as the flu virus and coronaviruses that cause colds. In winter, temperate countries have a peak incidence caused by these pathogens, but viruses circulate throughout the year in the tropics. The researchers looked at the factors that control the seasonality of viral infections, as well as data on the SARS-CoV-2 pandemic.
It turned out that the survival of viruses in the air and on surfaces, as well as susceptibility to infections and the tendency of people to gather indoors, depend on seasonal changes in temperature and humidity. Compared to influenza and other respiratory diseases, the new coronavirus has a higher rate of transmission due to the lack of immunity in most people. That is why the factors influencing seasonality cannot stop the spread of COVID-19 in the summer months.
Only when many people have a strong immunity after immunization or recovery will the virus become more susceptible to seasonal factors. Prior to this, strict measures must be taken to limit the spread of coronavirus infection.
It is known that since the beginning of the pandemic in the world recorded 29.75 million cases of COVID-19. In many countries around the world, the epidemiological situation is still deteriorating.
