Throughout the period of the coronavirus slotxo crisis Public health officials around the world have advised people to take important precautions to protect themselves.

Everyone was advised to wash their hands often. And wash properly Keep your distance from people outside your family. And one of the most important precautions is to wear a mask.

But as the pandemic continues Some people are also questioning, can wearing two masks at the same time provide more protection against the virus?

Some health experts said Wearing a double mask may help in certain situations.

Dr. David Hamer, an infectious disease expert at Boston University, told the Associated Press that wearing a mask is enough for most situations. But the mask must be the right size and not too loose.

The US Centers for Disease Control and Prevention (CDC) recommends wearing a cloth mask made of two or more layers of cloth. It is necessary to cover both the nose and mouth. And should fit the face

But even with the best fit mask. But some people may need extra protection in certain situations. For example People at risk of a serious illness if infected with the corona virus may want to wear a double mask. Or those who will have to be with others for a long time In a building or must be in a closed area such as on an airplane

For high-risk situations, Dr. Monica Gandhi, infectious disease specialist at the University of California. San Francisco campus It is recommended to wear a cloth mask and a medical mask at the same time.

She said wearing both a cloth mask and a mask at the same time. By putting any type on the upper floor May help prevent even more coronavirus infection And that wearing a double mask can provide protection just like wearing an N95 mask.

The N95 mask is a type of personal protective equipment designed for health care workers and outpost medical workers, so the CDC does not recommend the general public to wear it.

Dr. Gandhi also recommends that people living in buildings with high infection rates Wear a double mask And there is another recommendation for situations in which a person wants to be protected at the highest possible level. That is a mask made of two layers of fabric with a filter material in the middle.

However, Dr. Gandhi has one important piece of advice for people who wear a single cloth mask for everyday use. That is, the fabric must be made of a well woven material. Should use a cloth that is at least two layers thick. This will make it more difficult for the virus-carrying particles to pass through the material.
