(ANSA) - GENOA, 05 MAY - The transmission of covid in closed environments by aerosolization would be "much less likely" compared to contagion by direct contact with drops of saliva, the so-called 'droplet', or what remains on mania and surfaces. This is the thesis that emerged from a scientific study conducted by a research team at the San Martino di Genova hospital illustrated to ANSA by the infectious disease specialist Matteo Bassetti on the occasion of the World Day dedicated to hand hygiene.
"As part of the surveillance carried out by the chemical engineering of the clinic, a bubbler was placed inside some wards at risk with covid-positive patients - explains Bassetti -: the instrument did not detect any traces of viruses in the air".
Bassetti points out that at the international level to date there is no certain scientific research that "demonstrates how within a closed environment the subjects who never came into contact with each other became infected".
"In a room where there is a covid patient, not detecting the presence of the virus in the air, it seems to me that it is quite a fact - he underlines -. They say that if you enter the restaurant the virusa aerosolize and you eat the particles and we inside a room. where we have a positive covid patient, with the bubbler very close to where he breathes, we do not detect the presence of the virus ".
