A slowdown video shows the trajectory of the sneeze that can reach up to about 8 feet. Adhesive coronavirus can be spread through sneezing and coughing sprays. U.S.A. scientists filmed a video clip of a healthy person during a sneeze, which slowed from 25 seconds to a minute and a half. They found that viruses found viral in coughs and sneezes can travel in a humid and warm atmosphere at speeds of 10-30 feet per second.
This creates a cloud of infectious and 'turbid' gas capable of reaching somewhere between seven and eight meters away. A humid and warm atmosphere inside the turbulent cloud of gas allows the sprays to evaporate for much longer than usual suggests that the social distance limit due to coronavirus is two meters - or at least four times shorter if sneezing is taken into account. today they are based on outdated models.
“Although such social distancing strategies are critical at the present time of pandemic, it may seem surprising that the current understanding of host transmission routes in infectious respiratory diseases is preached in a 1930s disease transmission model that, by modern standards, it seems too simplistic, ”said Lydia Bourouiba.
“Implementing public health recommendations based on these older models may limit the effectiveness of the proposed interventions. These distances are based on the estimates of the range that did not consider the possible presence of a high-speed cloud that transported the points over long distances, "she added. remains trapped and accumulated in the driving reindeer. Eventually, the ‘turbid gas cloud’ loses momentum and the splashes left inside the cloud evaporate.
