As a doctor, I can say that it's not a big rumor. Authorities such as CDC and people who trust to review medical evidence and make rules to help us stay safe - Meet us that we have to wear masks to beat the virus.

In April, theCDC Issuing a recommendation that you should wear a mask when not at home, when you mix with people who do not live in your household or in situations where social distance is difficult. (This does not apply to children under 2 years old, nor to babies.)

In June,WHO You have recommended that everyone be encouraged to wear face masks in places where the risk of community transmission is increased.

The best experts from American infectious disease for more than 30 years,Dr. Anthony Fauci, never give an interview (and it gives them a lot) without emphasizing how crucial the facial mask bearing for our health and to stop the pandemic.

There are three types of facial masks:

• Face coverings. Fabric coatings in fabric, often homemade, which vaguely cover the nose and mouth. Home coatings must be constructed of cotton fabric or NonStrettchy polycoton, with a minimum of three layers in a closer duck or fold design. He should cover the mouth, nose, cheeks and chin.
• Medical face masks. These are medical masks generally worn by health professionals as part of their daily tasks. They are a type of PPE and use must be reserved for use in clinical / hospital settings.
• Medical face masks / formal EPP. These are part of the personal protective equipment (EPP) carried by the medical personnel (for example, the N95 respirator mask). These masks are designed to seal tightly around the nose and mouth. The use of these masks is reserved for the management of patients at high risk of CIVID-19 infection, or who are known to be infected and should only be worn by medical staff.

The face masks do two things.

• Containment. If you are infected with COVID, the masks provide a barrier to the viral particles you breathe, which reduces the chances of transmitting the infection to another person.
• Protection. The masks help you prevent you from breathing virus particles, reducing the chances of becoming infected.

The masks are better to confinement than protection. Here is the problem: we have no idea that can be infected. Eighty percent of people with COVID-19 have no symptoms and are not aware that they are infected. Those who continue to develop symptoms are often the most infectious in the early days of their infection as they are still asymptomatic.

This is why the port of masks is a tool particularly useful for stopping people infected with unconsciously infecting others.

• A simple toilet glove on the mouth prevents the breathing droplets. In a recent study (April 2020) in New England Journal of Medicine, the number of breathing droplets produced during the normal Word was almost completely erased by covering the mouth with a wet toilet glove.
• Countries where mask wear is mandatory have lower mortality rates. A recent research study (202020) compared the mortality rate of COVID-19 infection in 194 countries. They discovered a statistically significant lower mortality rate in countries where mask wear was mandatory. The mortality rate increased by 8 per week in these masks use countries, compared to a 54% increase in those that did not.
• Hide by a positive passenger from Covid-19 on a protected flight by other passengers. In an interesting case report, a man who presented symptoms and subsequently tested positive in Covid-19 stole from Wuhan, China to Toronto. He wore a mask for all the flight, and none of the 25 people sitting at six feet from him or in the rows around him was positive tested after monitoring and active tests at 14 days.

Arecent study Published in the newspaperAdvance of science Compared the capacity of 14 different face masks to filter the respiratory droplets during the word.

• The worse mask carried out was a fleece mask, with a transmission fraction of 110% - a higher transmission rate than not to wear mask at all!
• Polycotton and cotton masks had a similar reduction in transmission to a N95 valve respirator mask (the valve is installed to allow inhalation and expiration). The transmission fraction of these was between 0.2% and 0.4%.
• The most powerful mask was a bandana. Wear a wager around the neck and pull it from top to cover your nose and mouth, seems to encourage greater breathing particles to break in smaller ones.

The CDC also asserts that the masks should not be worn by "someone with breathing difficulties" or "whoever is unconscious, incapable, or who would not be able to delete the unattended mask".

Each state has produced its own orientations on exemptions. For example, the health service of New York City (NYC) said "it is not necessary to wear a facial mask if you have a health problem that allows you to tolerate one." (However, they do not stipulate what these conditions of health could be.)

There are very few people who can not wear mask because of the chest or lungs. A US respirator, David Kaufman, but not antipathic, commented, "If you can wear a scarf, you can wear a face mask!"

While wearing a mask is one of the fundamental principles of Fauci, there are times when you can remove them safely. "When I see people on a beach running with person around them, good for you, you know, do it. You do not need to be locked outside," he said . However, if there are many people around, hide you. "If you think you're getting closer to people, you know, turn a mask back. But if you walk with your dog or your wife or husband or someone you're in the house with anyway, and you" will not stay separate from them and do it. "He also explained that there was no need to go to the extreme." You could see your friends, "he says." I want say, what I'm doing myself right now, I'm very careful to wear a mask, but every night, and it's now late at night, because when I go home, my wife and I go out For a Jog mile, walk, everything you want to call it. And I do that, "he explained, pulling his mask around his chin. "That's like that. And I'm talking with her. If I see 50 meters ahead, someone came, I'm going like that," he continued, returning his mask on his face. "We pass them." Hello. How are you? 'And then I'm outside. You can do it. You can do it. "

The use of a transparent plastic face shield may seem an attractive alternative to a mask, but these do not seem to be so protective.

Face shields have some advantages: they cover your eyes, can be reused indefinitely, are easy to clean and communication is easier than with a mask.

However, the search suggests that in some situations, for example, if someone touches directly into your face, if you wear the shield at work, or if you move droplets of much respiratory, you can more easily pass from the sides of the shield. In fact, face shields are only 45% efficient to reduce the transmission of respiratory droplets.

The CDC does not recommend the use of a face shield instead of a mask. However, if you can not wear a face mask, a face shield is better than nothing at all.
