On the subway, no chatter between passengers or phone calls. For now it is only a suggestion of the French doctors, but it is not certain that this idea will not be officially embraced by the government soon.
The alarm of the doctors
According to the members of the prestigious academy founded in the nineteenth century, however, this would not be the case at all and it is precisely this belief that prompted them to launch a serious alarm about the contagion by air on public transport and to ask that more be done to break, or at least weaken the transmission chain of the Coronavirus, which currently does not seem willing to let go. "The obligation to wear masks on public transport - reads the note distributed directly by the" Body - should be accompanied, when not social distancing is possible, from a simple precaution: also avoid talking and making phone calls. "Also because when making a phone call, many people are tempted to lower or slightly move away the mask, due to the belief, real or not , that one's voice filtered by the personal protective device, as well as by the smartphone, can reach the pr own interlocutor.
.
"Most infections - continue the scientists - occur in situations where people pay attention." This means that what has been done so far may not be enough.
Precisely for this reason, according to the biologist doctor and member of the Academy, Patrick Berche, inviting people to silence on the subway is a measure of common sense. "In a carriage where there are only three people there is no problem. , but if you are only two centimeters away from the next person it is very different ».
Contagion in closed places
According to a recent study conducted by researchers from the University of Cambridge and Imperial College London, in fact, conversing in a poorly ventilated place can spread respiratory droplets that carry the virus, just like coughing.
Covid-19 mainly spreads from one infected person to others, through respiratory droplets when coughing, sneezing, or just talking or breathing.
Larger droplets fall to the ground in seconds or minutes, while smaller particles can remain in the air. Talking generates these small droplets that can spread and accumulate more easily in an "area without" adequate ventilation.
Research also suggests that it takes only seconds for viral particles at levels above the quantity to infect a person less than two meters away.
According to an international study, however, there are people who are resistant to the Covid-19 virus.
, with many people now used to wearing fabric masks and many companies that have been producing masks approved by the health authorities for months. "This change - observes the Academy - risks arousing misunderstanding and could revive doubts about the solidity of official policies".
The French situation
France is currently one of the countries most affected by the second wave of Coronavirus, so much so that hospitals host more patients with Covid-19 than in October, when President Emmanuel Macron had imposed a second lockdown.
The new suggestion, therefore, hopes to help reverse this trend.
