On Thursday, the World Health Organization admitted that it was possible to catch the coronavirus interior because it is in the air, something scientists have long alleged."Covid-19 outbreaks reported in some closed environments, such as restaurants, discos, places of worship or workplaces where people can be screaming, talking or singing," the agency announced . "In these homes, aerosol transmission, especially in these places inside where there are crowded and poorly ventilated spaces where infected people spend long periods of time with others, can not be excluded. »

So, how can you protect yourself if the virus is in flight?JAIMIE MEYER, MD, An infectious disease specialist Yale medicine and associate professor at Yale Medicine School, explains.

"In the case of Covid-19 disease prevention, we know that some key work behaviors: social distancing, wearing face coatings, insulating in case of illness, and the monitoring and isolation of infected persons' contacts," says Dr. Meyer on. Also, keep the hand washing and the use of hand disinfectant when soap and water are not available.

Due to the fact that many of these preventive measures are impossible within spaces such as crowded bars, adorant centers, shopping centers, etc.-dr. Meyer explains that indoor common areas are dangerous. "If we knew that the virus was in flight and that the virus level was quite high in the air to someone infected other (which remains to be determined), we would need to make an even bigger effort to avoid spaces common interiors, even if wearing a face fabric coating, "she says.

While the N95 masks "would be better protection against viruses in the air as the face cloth coatings," says Dr. Meyer on that they are "little practical for everyone because they are relatively few and necessary for health workers. In addition, in order to work well, they must also have a tightness around the mouth and nose, which means that they must be dimensioned (adjustment tested) and incapable of seal in people with the hairs of the face. "As a health professional on an infectious disease service, I spent hours with N95 masks and can attest that they are very difficult to tolerate for a long time! She's.

It has been discussed the ability of UV lights to effectively kill the virus. In addition, the installation of effective air filtration systems has been discussed. However, Dr. Meyer underlines, "there is no recommendation from the CDC or EPA to date on UV lamps or air filtration systems, although adequate ventilation is still important to reduce the Propagation of the disease, even if it is only in droplets. »

However, if the virus was in flight, even in the hospital environment, "simple door closed to a hospital room would not be enough to contain propagation," explains. Instead, people must be placed in isolation chambers "Negative pressure", where the air is obliged to circulate from the outside (and not inside).

So you have to avoid common spaces inside, hard as it can be, and pass through this pandemic to your healthier, do not miss theseThings you should never do during the pandemic coronavirus.
