An international research team played the role of atmospheric conditions in the spread of Sars-Cov-2, the virus responsible for the Covid 19. Future.
Your work could make it possible to better predict Covid 19 seasonal epidemics in the future. A. study Under the leadership of the Spanish Institute of Ciècies del Mar (ICM-CSIC), two important indicators for the risk of pandemic enables: atmospheric pressure and relative humidity (or hygrometry), note the site Tamateo.

“These results underline how important it is to integrate climatic influences into epidemiological models. Understanding how environmental factors influence the transmission of the virus enables us to better anticipate,” explains Ignasi Vallès, one of the co -authors of the study.
Between September 2020 and February 2021, the researchers compared the epidemiological data collected by PCR tests, whereby meteorological variables were recorded almost 200 automatic stations in catalonia.
Spread through weather conditions facilitated
The study has therefore shown that unfavorable weather conditions such as low pressure (often at the beginning of autumn) and a low humidity can increase in the following cheeks, “interactions indoors” in which the Sars-Cov2 virus is likely to develop “.
Of course, the main factors for the transfer of pathogens remain social interactions such as mobility or use of interior and prevention guidelines (use of face masks, vaccinations, etc.). However, the influence of atmospheric changes explains “between 14 % and 45 % of the variability of the infection rate in the eight analyzed health regions.”
As a result, the team underlines how important it is to take into account the combined effects of atmospheric changes to the susceptibility to infections and human behavior.
