The study of the authorship of Chandini Raina MacIntyre, from the University of New South Wales, Australia, consists of a review of other research carried out by the same in 2015.
The height, MacIntyre and a team of researchers was testing the effectiveness of tissue masks used by doctors and other health professionals in hospitals in Vietnam and found that in many cases the accessory remained contaminated with viruses after being hand washed.
“[No novo estudo,] we askus if the adequacy of the wash played a role in the performance of the cloth masks in the old analysis, “he says MacIntyre to BMJ.
“It turns out that this may be the case.”
According to Galileo, by re-analyzing the data obtained in 2015, scientists detetaram hand-washed masks remained contaminated, while those washed in the hospital laundry room were clean, free of infectious agents, and safe to reuse.
“A sanitation must be done in Water at least 60 degrees centigrade with soap. Wash your hands in Water cold or warm, which may have been the case for health professionals in our first study, is inappropriate, ”says the scientist.
