Jose Luis Jimenez, the prestigious Spanish researcher who has revealed what is the great problem of FFP2 masks and why they can be useless instead of protecting us against coronavirus, has also revealed in a video the ease with which we we can spread covid-19 although we wear the mask permanently.
Jiménez, who is a professor at the University of Colorado (United States) and one of the great world experts in aerosol transmission, warns us of the danger posed by a bad fit of the mask, even if it is FFP2, considered one of the safest due to its high efficiency in filtering the virus.
This is how we get coronavirus even with masks
And is that the researcher has shared a video on his Twitter profile in which it is clearly seen how a person who wears a mask that does not fit well exhales, either surgical, cloth or FFP2, very demanding in recent days for his highly effective against the covid-19 virus.
So yeah mask fit is not adequate and the nose and mouth area are not well sealed, we come into contact with unfiltered air and, therefore, our possibilities of exposure to the virus and probable contagion. And, in case it is a person already infected who wears the mask without adjusting correctly, in the video shown on these lines it is also perfectly appreciated how the coronavirus transmits through the aerosol sprays by exhaling.
Masks and tips to avoid contagion
The images demonstrate the importance of wearing the mask properly, be it an FFP2 mask, a surgical mask or a cloth mask, although it also emphasizes the need to continue to respect the usual recommendations in the fight against the pandemic: social distance, outdoor activities and hygiene, since, even if we wear a mask and believe that this gives us protection, misuse can make us vulnerable to contagion or contagion even without knowing it.
Therefore, the best protection against the coronavirus is to ensure that the mask is correctly placed and that the seal with the face is adequate (a good way to check this would be through the mist that we exhale: fogged glasses would equal poor placement) and, of course, continue to comply with the basic rules of social distance, frequent hand washing, limiting social encounters and opting for the outdoors rather than a closed space.
