New Delhi: The world has been hit by another wave of the coronavirus pandemic.
However, the world is still looking for a COVID-19 vaccine with which to fight the coronavirus pandemic. But according to research, coronavirus can be easily defeated even without COVID-19 vaccine.
According to several studies, the spread of the COVID-19 virus can be prevented if at least 70 percent of the public wear masks continuously.
According to research, the use of masks plays an important role in preventing the spread of the COVID-19 virus. The research, published in the journal Physics of Fluids, assessed studies on face masks and reviewed epidemic reports on whether they reduce the reproductive numbers of viruses to infected people.
Scientists say that at least 70 percent of residents using the highly effective facemask in public can be prevented.
According to scientists, a major aspect of the face mask function involves the size of droplets of fluid extracted from the nose and mouth when a person talks, sneezes, coughs, or even breathes. He stated that large droplets are the most common with sizes of 5–10 μm. Small drops below 5 μm are possibly more dangerous.
Scientists said that human hair is about 70 microns in diameter. There are many types of facemasks in use, such as cloth masks, surgical masks and N95 masks. He stated that it can only filter the latter aerosol-size droplets.
They found that face masks made from hybrid polymer materials can filter particles at high efficiency, as well as keep the face cool.
Based on the analysis, the researchers also underscored the importance of frequent use of skilled facemasks such as surgical masks.
