6-second rule to avoid infection

Social distance, the use of masks, personal and environmental hygiene: the rules for fighting coronavirus spread are now known. All are measures recommended by experts to reduce the dose of viruses we are in contact with.

But what is the amount of Covid-19 we are exposed to every day? “Like any other poison, viruses are usually more dangerous in large quantities. “Small initial exposures tend to lead to mild or asymptomatic infections, and large doses can be fatal,” Professor Joshua Rabinowitz and researcher Caroline Bartman told the New York Times. “When you enter a building or an office where someone has had coronavirus, it’s not as dangerous to sit next to that infected person during an hour’s train journey,” they added.

For this reason, social distancing and proper hygiene help reduce the dose of viruses to which we are exposed. As Corriere explains, special care must be taken to prevent exposure to high doses of Covid-19. “These doses are most likely during close interactions with people, but also during meetings in crowded places or when we touch the face after we have received a significant amount in the hands.” The two researchers explained in fact that “human interactions are more dangerous indoors and over short distances, with an escalation of increasing doses with exposure time.”

“In terms of transient interactions, which violate the rule of maintaining a distance of 1.80 meters, such as when paying at a supermarket, they should be as short as possible, aiming at the rule:” within one meter and eighty centimeters, only six seconds “.” The WHO currently recommends that a minimum distance of at least 1 meter be maintained by another person.

This distance is also suggested by our Ministry of Health. However, for U.S. health experts, it is necessary to maintain a distance of 1.80 meters from others. And if this measure is not possible, for example when we pay at the supermarket, the rule to follow is that of a short contact, at most EVERY SECOND.

Experts add that “food and packaging that have been exposed to someone with the virus appear to pose a low risk.” “Healthy people, who are together in a store or in a workplace, have a tolerable risk, as long as they take measures such as masks or distances.” All of this is data that needs to be remembered to cope with the second phase of the emergency. / Giorgia Baroncini, Il Giornale
