We report two brief periods that clarify the importance of mechanical ventilation in the fight against Covid 19 contagion: .... "Scientists collected the virus two and four meters away from patients, showing that the virus sampled in the air was capable of infecting cells in the laboratory. The genome sequence of the isolated virus was identical to that of the swab of a symptomatic patient just admitted to that room. Room that had six air changes per hour and was equipped with filters efficient, ultraviolet radiation and other safety measures for inactivate the virus. These measures could explain why they were sampled only 74 viral particles per liter of air. Certainly in spaces that do not have as good ventilation as they could be schools and offices, the viral particles would have been more. ".... Other experts say it is difficult to estimate the risk of infection with these results. “I'm not sure these numbers are high enough to cause someone to become infected. The only one The conclusion I can draw from this document is that it is possible cultivating viable viruses sampled in the air, and I admit that is not a little "he has said Angela Rasmussen, a virologist at Columbia University in New York interviewed by the New York Times.
