HEALTH TIPS : Blue surgical mask 'failed' to protect against corona, big disclosure in study
In view of the threat of corona infection around the world, health experts are appealing to all people to continue to use protective measures. To protect against corona, emphasis is being laid on wearing masks, taking care of hand hygiene, and following social distancing rules. Due to the havoc of Corona, which has been going on for the last one and a half years, now wearing masks has become a part of people's habit, but can any type of mask give protection from infection? Do you know how effective the mask you are wearing is in keeping you safe from infection? In a recent study related to this, scientists have made a big disclosure about the blue color surgical mask. In the study, scientists have described such masks as ineffective in protecting against corona.
In a study conducted by the University of Waterloo in Canada, scientists have reported that the blue-colored surgical face masks used by most people during the pandemic have not been found to be effective in protecting against Kovid-19 infection. Scientists say that people should wear other types of masks to stay safe from infection, because surgical faces may not be considered more effective in blocking aerosol droplets. Let us know about this study in detail in the next slides.
Why are surgical masks not effective?
In this study conducted on the effectiveness of the mask, the researchers say, "The blue surgical mask popular during the epidemic can be considered effective only up to 10 percent, mainly because this type of mask covers the face well. do not find. Scientists say that as new and more infectious variants of corona are being discovered, it is very important for people to wear masks. Masks like N95 and KN95 can protect against corona more effectively.
wear a face mask
There is no doubt that proper covering of the face is most essential to prevent infection, says Dr. Serhi Yarusevich, professor of mechatronics engineering at the university and lead of the study, although when it comes to controlling aerosols, different There has been a big difference in the effectiveness of the mask. Many people wear masks that do not fit properly on their faces. In such a situation, droplets of aerosol can come out, which can cause infection to people. Blue surgical masks have not been found fit to protect against infection on this basis.
Which masks are more effective?
Researchers say that N95 masks have been found to be more capable of filtering aerosol droplets than surgical masks. Professor Yarusevich says it is common that a mask that will cover the nose and mouth well can be considered more effective in protecting against infection. People should use more N95 masks if available.
N95 masks are believed to be more effective
It is worth noting that earlier, Michael Osterholm, a former Kovid-19 adviser to US President Joe Biden and top epidemiologist, also said that the type of mask people are using may not be considered more effective in protecting against infection. . Earlier this month, Michael Osterholm said that people should start wearing N95 respirator masks, which may be more effective in protecting against infection. We are in a very unfortunate situation, it is not very clear yet to what level to protect against corona. At present, people need to be very careful about the use of masks.
