According to a recent study published in the Journal of General Internal Medicine, which echoes research conducted by American doctors Eric Goosby, Monica Gandhi and Chris Beyrer, it seems that the use of masks not only prevents the external transmission of covid-19 coronavirus to those who wear them, but is very likely to help those infected to alleviate their symptoms, even making them asymptomatic.
This could be explained by the evidence that the widespread use of masks prevents asymptomatic people from unconsciously spreading the coronavirus, which is logical and holds no secrets. However, there is evidence that the use of masks is important even among infected people.
We are talking about the case of the Argentinean cruise ship in which all the passengers on the ship were provided with masks as soon as an outbreak was detected on board. Well, despite the fact that more than half of the occupants of the cruise ship were infected, of these, only 19% showed symptoms of the disease.
Obviously the study is broader and offers all kinds of medicines and technical conclusions to be considered; what does not seem to raise doubts is that we are going through a pandemic of unpredictable consequences, and that, until the time comes when our scientists find a definitive cure, any precautionary measures will be few and far between.
