VSome countries recommend for example 2 meters of social distance. In Belgium, the rule is 1.5 meters. But is it enough to avoid being contaminated? Emmanuel André, inter-federal spokesperson, replies: “The virus is transmitted via droplets, it is in these droplets that there are many viruses. They will fall to the ground after a meter, a meter and a half. This is what we can notice with a postilion. “
“The question is what is the role of the smallest drops,” explains the specialist. They fall less quickly but will also contain less virus. They have not been shown to play an important role in transmission. Zero risk in medicine never exists. If you take 15 meters, the risk will be further reduced. But it is not always necessary or possible. The basic principle is that the droplets that contain the most viruses, the main vectors, will fall after a meter. “
