Darreres investigacions: les màscares poden evitar la transmissió de coronavirus estacional

According to a research paper published in nature medicine Wednesday by Professor Benjamin cowling, CO director of the World Health Organization Center for infectious diseases and epidemiological control, School of public health, University of Hong Kong The relative content of virus in the exhaled air under the condition of mask or without mask. The results showed that in 111 subjects who had been confirmed to be infected with coronavirus, influenza virus or rhinovirus, masks reduced the detectability of influenza virus in respiratory droplets and seasonal coronavirus in aerosols, but did not reduce the detectability of rhinovirus.

El nou coronavirus (sars - cov - 2) està estretament relacionat amb el coronavirus estacional i pot tenir una mida de partícula similar. Per tant, l’equip creu que les màscares quirúrgiques poden reduir el coronavirus estacional en gotes respiratòries i aerosols, cosa que suggereix que el fet d’utilitzar aquestes màscares en persones amb nova infecció per coronavirus pot ajudar a frenar la propagació del virus.

& quot;Nature & quot; published the preliminary results of German medical experts & #39; research on confirmed cases of new coronavirus infection, which showed that the replication of new coronavirus in patients & #39; upper respiratory tract was more active. In the early stage when patients & #39; symptoms were still light, that is, within the first week after symptoms appeared, the virus discharge ability of new coronavirus in upper respiratory tract was the strongest. Experts said the results also mean that the spread of the new crown virus is mainly controlled by droplets. Wearing a mask can play an effective role in this.

En una entrevista a la ciència, l'acadèmic Gao Fu, director de la Xina CDC, també va assenyalar que les gotes tenen un paper molt important en la difusió del nou coronavirus, per la qual cosa haurien de portar màscares.
