researchers from the University of Nicosia (University of Nicosia), using computer models, evaluated the effectiveness of wearing medical masks to protect from COVID-19.
the results of the new studies have shown that the mask can actually reduce transmission of the virus. However, the filtration efficiency of the products negatively affects cough. So, the more a person coughs, the lower the effectiveness of the mask as it starts to pass through itself more potentially dangerous phlegm.
So, experts have found that drops (even with a light cough) can travel relatively long distance of one meter. However, without the mask drops move twice as far, so wearing a mask can still be useful, said the researchers.
– droplet Sizes are constantly changing during cycles of coughing as a result of interaction with the mask and the face. During repeated cycles of cough the ability of the mask to accumulate phlegm, not giving her the external environment, is reduced. The use of masks will not provide complete protection against the virus. Therefore, we recommend to maintain social distance, – said the researcher Dimitris Drikakis.
