How to Protect Yourself from Covid - Covid Face Mask

With the new COVID from China spreading across the globe, many people want to protect themselves from infection.
And one of the most debated topics right now is the use of face masks.

Does the mask work against COVID?

Meanwhile, the CDC recommends:
1. Wash your hands (20 sec) thoroughly throughout the day, especially after using a bathroom and before eating.
2. Avoid touching your eyes, nose, and mouth with unwashed hands.
3. Avoid contact with people who are sick and COVID positive.
4. Disinfecting commonly used surfaces
This advice will help protect you from a whole host of infections, including COVID.
But the CDC does not recommend the routine use of surgical masks to protect against covid infections.
And some experts say that Masks and gloves do a better job of spreading bugs than stopping them.

Meanwhile, the covid fears are leading to mask shortages around the world.

The World Health Organization (WHO) just warned of a global "chronic shortage" of personal protective equipment that could shield individuals from covid.
Personal protective equipment does not mean specifically surgical masks. It includes surgical masks, N95 respirator masks, gloves, goggles, and gowns.

Masks are now hard to come by in the United States, as well.

On Thursday, the National Community Pharmacists Association released a national survey that said 96% of local pharmacies are experiencing a shortage of surgical masks, and nearly 40% don't have enough N95 respirators.

The websites of CVS and Walmart show few to no surgical masks and N95 respirator masks.

But what is the role of these masks, and do we really need them?

Face masks can help prevent the infection, but that role is limited in real-world situations. There is some evidence that wearing a face mask can protect you from transmitting the covid viruses from your hands to your mouth, probably because you pay more attention to NOT touching your face when you’re wearing it. You also have protection from “splash” droplets if an infected person sneezes or coughs around you. And also, as the COVID is airborne and can stay live in the air for 3 hours, for this reason, it's important to wear a mask to stay safe.

But there are several reasons why face masks are not ideal. For one, it’s tough to find one that fits perfectly around your nose and mouth or to keep it on for a long period of time. The minute you scratch your nose or touch your mouth behind the mask, you’ve lost the protection that the mask is expected to give you.

There are particular guidelines about when to use masks in hospitals and what protection to wear depending on the type of infection a patient has or is suspected of having.

For example, healthcare workers need to use a rectangular surgical face mask when a patient requires droplet precautions. These surgical face masks are intended to prevent infections spread by large droplets when someone coughs, sneezes, or talks. This includes infections like influenza, whooping cough, and meningococcal meningitis.

Then there are airborne precautions. Some lung or throat infections spread when small viral or bacterial particles stay suspended in the air and can be inhaled by other people. The covid is believed to fall into this category. This category also includes SARS, measles, chickenpox, and tuberculosis. In these cases, all people coming into close contact with the patient should wear an N95 respirator mask. These masks have a special air filter designed to protect from tiny airborne particles. Unlike surgical masks, they fit a person’s face and are usually rounded in shape. In theory, all the air a person inhales is filtered through tiny pores in the mask.

The covid is thought to spread through contact, droplet, and airborne; the most appropriate mask to prevent inhalation would be an N95 mask.
