What can be prevented after the mask?

In many countries around the world, the use of masks is a popular way to prevent infections. Especially in China, where the spread of coronavirus has started, people always wear nose and face masks to protect themselves from air pollution.

However, virus experts, called virologists, are skeptical about the effectiveness of the mask in preventing airborne virus infections.

Can a virus be prevented after wearing a mask?

However, there are some examples of the benefits of usingthis mask to prevent hand-to-mouth infections.

 The first surgical mask was introduced in the eighteenth century. But it was not until the Spanish flu pandemic of 1917 that the mask reached the masses.

About 50 million people died in that epidemic.

"Ordinary surgical masks are not enough to protect against airborne viruses and bacteria," Dr David Carrington of St George's at the University of London told the BBC.

 "Most viruses are airborne," he said, and these masks are so loose that they can't filter air properly. Moreover, whoever is using this mask, his eyes are open.

 However, this mask can help reduce the risk of sneezing or coughing up the virus. And it also gives some protection against hand-to-mouth infections.According to a 2016 study in New South Wales, people touch their hands with their hands an average of 23 times per hour.Jonathan Ball, a professor of molecular virology at the University of Nottingham, said a controlled study in the hospital found that face masks made as respirators could prevent influenza.
