The use of face masks has been made mandatory across Pakistan for the prevention of corona virus, while the World Health Organization last week recommended the use of masks in public places in its new recommendations.
Prior to these recommendations, research from McMaster University in Canada presented evidence that common face masks made of cloth were effective in preventing corona virus, especially masks that used several layers of cotton cloth. Which help prevent viral particles from spreading into the environment.
In fact, researchers say that cloth masks may be effective in preventing the spread of the new Novel Coronavirus disease Code 19, as it blocks 99% of viral particles.
Similarly, the medical journal The Lancet analyzed 172 research reports from 16 countries that examined the risks of spreading the virus, including social distance, the use of face masks and blindfolds.
These reports examined the epidemics of COD 19 as well as two other Corona viruses, SARS and MERS.
“We were stunned to see the effect of precautionary measures. In epidemic diseases, we often see minor effects, but the effects we saw were greater or greater,” the researchers said.
The researchers said that the use of cloth face masks among the people could be effective, which not only risked the spread of the virus by the infected person, but also healthy people can avoid the virus.
At present, at least 30% of coronavirus patients worldwide are asymptomatic, so using a face mask can help protect a healthy person from the epidemic.
But most people make mistakes when using face masks that can cause a virus.
Just cover your face
If only the face is covered with a face mask, it increases the risk of disease, not decreases.
According to Thomas Rousseau, head of the epidemiology department at the University of Buffalo in the United States, we usually breathe through the nose and transmit viral particles into the body through inhalation, if you are already a victim of code 19 and only wear a mask. If you cover your mouth, sneezing can spread viral particles into the air through the nose.
In simple words, it is also important to cover the nose while wearing a face mask, otherwise the risk is not reduced.
Keep the mask away from the body or clothing
It can also increase the risk if the corona virus is present on clothing, parts of the face or body and spreads to those areas while loosening the mask.
According to experts, wearing a mask incorrectly increases the risk of bacterial contamination, if the inside of the mask is attached to an object such as hair, chin, neck, hands or clothing and then applying it to the mouth increases the risk of virus. ۔
If you loosen the mask, never hang it around your neck as it also increases the risk. The main purpose of face mask is to protect the nose and mouth from viral particles. After removing the mask, do not touch the front part but place it on the corner. Grasp the cords and separate.
Don’t forget to wash your hands before and after taking off the mask.
Keep it loose on the face
If the mask is of any kind, it must fit perfectly on the face and nose, so as to form a barrier that blocks air as much as possible. If any type of mask is left loose, it will not help prevent viral particles.
Do not cover the nose properly
To prevent the virus, it is important to cover not only the nostrils but the entire nose. If only the nostrils are hidden, there will be a gap that will not be able to stop the flow of air, which is why experts recommend covering the upper part of the nose with a mask.
Do not wash the mask thoroughly
If you want to re-use the mask, it is important to make sure that it is protected from germs. Medical mappers recommend washing the masks made of cloth in the washing machine. If this is not possible, then at least once. Wash well.
If the mask is unusable, it should be safely discarded.
