If the fight against the corona virus is not complicated enough, it turns out that in winter it is going to be more difficult, and it is not just because of the flu.
A former World Health Organization official warns that a wet face mask is less effective because water restricts airflow and reduces the amount of its viral filtration, the Daily Mail reports.
Although today we already know that masks are perhaps the best protection against the corona virus, but as mentioned a former senior member of the World Health Organization asks users to replace their face mask if it gets wet because the moisture damages the mask sealing makes it vulnerable and penetrating.
Professor Tim Spector, who runs the Covid-19 Study Symptom app, warned the UK government that the public is unaware of the risks involved in a wet face mask and said it "would be useful if clear advice was given to the public".

Dr. Simon Clark, a professor of cellular microbiology at the University of Reading, even went so far as to say that "a damp mask is no different from a dirty handkerchief attached to your face." He claims, "If the mask becomes too moist even after coughing and sneezing, it's probably a good sign. ".

It is important to remember that there can be large differences in effectiveness between masks, depending on the type of fabric from which it is made.
"It very much depends on the quality of the fabric. If the mask is made of Egyptian cotton fabric with a density of 600 threads, it is very different from a mask made of a simple, non-woven t-shirt fabric," said Dr. Ramzi Asfur, an infectious disease specialist, in an interview with Business Insider. The density of the material from which the mask is made, combined with the moisture, can significantly affect the protection you receive.Although the
authorities in some countries recommend replacing a mask when it is too moist, it is estimated that public awareness is very low.In France the situation is different, where it is mandatory to wear masks outside, and the public is told that is recommended to bring a mask while in case of rain or moisture.
"I always make sure I had at least a face mask once free and clean every time I go out so I could replace the one I wear if it gets wet or I'm wearing it for a while," explained Clark, adding that warning Also applies to masks soaked in moisture from respiratory drops.
