More than a year after the start of the Covid-19 epidemic, numerous studies have shed light on the virus, its variants and its modes of transmission.
At the start of the Covid-19 epidemic, everyone feared coming into contact with the coronavirus everywhere and in particular through objects or on surfaces. Studies then estimated that it could last for hours. Since then, research has progressed. An American study published at the end of January shows that the risk of becoming infected by touching a contaminated surface is less than 0.05%.
A study carried out in the Raymond-Poincaré hospital in Garches (Hauts-de-Seine), during the first wave, underlines that the transmission occurs first by postilions or aerosols. Contaminations have clearly decreased since wearing the mask. Since October, the Institut Pasteur has been studying the sources of contamination. “It’s the meals, which really are one of the circumstances of transmission most reported, when it comes to meetings with your family beyond your home, and with your friends. In the professional environment, it is the shared offices and the places to eat “, explains Arnaud Fontanet, epidemiologist at the Institute and author of the Comcor study.
