Small, simple gestures could be the ones that will save us from the virus, or at least slow down its spread. If the temperatures are not conducive to leaving the windows open at home, it would be a good way to limit the circulation of Covid-19.
This summer, the WHO declared that the aerosol contamination of Sars-Covd2 is something to be taken very seriously. Indeed, microparticles expelled by coughing and sneezing can remain suspended in the air and then be breathed in.
Many scientists in the medical profession thus encourage the ventilation of interior spaces. This is the case of Anne Casetta, head of the hospital hygiene service at Cochin hospital in Paris, who explained this theory in an interview with Le Parisien.
“Opening the windows wide reduces the concentration of viruses in the air. We know that contamination depends on the infectious dose. The more you dilute it, the lower the risk of getting infected. Much of the virus goes outside, ”she says.
Some countries have even adopted this practice as a mandatory measure. This is the case in Germany, where Chancellor Angela Merkel has added room ventilation as an official recommendation against the coronavirus.
