Two years have passed since fighting the Corona virus. Even after the Kovid 19 vaccination, today the world is under threat of new variant Omicron. For this reason, it has become very important to follow the safety rules even after vaccination. Wearing a mask is also very important under the safety rules, but do you know that cloth mask does not completely protect against corona.
The World Health Organization (WHO), in its guidelines issued in December 2020, said that masks play an important role in protecting against corona virus, but still the mask is not able to completely protect against corona, even if you use it. No matter how well you use it, but a properly sanitized mask can be effective.
Various types of masks are being used as a precaution against COVID-19. U.S. The Centers for Disease Control and Prevention (CDC) has divided the mask into several parts. In which cloth masks, masks made of cotton or synthetic fabric, surgical or dispensable masks, which are of three layers. Apart from this, N95 masks include non-surgical masks of curved design with four or five layers.
Why is it necessary to use a mask
According to experts from Mayo Clinic, USA, wearing a cloth mask restricts the breath coming out of the mouth to the layers of the mask. At the same time, the wearer’s speaking, coughing or sneezing does not affect others. It acts as a protection to protect the wearer from inhaling droplets left by others. The most effective fabric masks are made of several layers of tightly woven fabric, such as cotton. At the same time, it is difficult to ascertain whether the masks sold in nearby shops comply with international standards. Apart from this, it is also not clear whether masks protect against virus infection or not.
