COVID-19 Coronavirus: Why we wear face masks?

  • 2020-04-07 10:26:27

There is increasing evidence of asymptomatic transmission, people with the virus who show little or no symptoms. Especially through younger people who have milder cases and don’t know they are sick but are still infectious. Since the W.H.O. and the C.D.C. do say that masks lessen the chances that infected people will infect others, then everyone should use masks.

COVID-19 is transmitted by droplets and close contact. Coronavirus is spread by droplets that can spray into the air when those infected talk, cough and sneeze.

Researchers at the Massachusetts Institute of Technology (MIT) in Cambridge, USA, used high-speed cameras and other sensors to accurately assess what happened after coughing or sneezing.

They found that exhaling produced a small, fast-moving cloud of gas, which could contain droplets of varying sizes-and that the smallest droplets could be carried long distances in the cloud.

These can enter the body through the eyes, nose and mouth, either directly or after touching a contaminated object. But if these people wear masks, these droplets may be curtailed, it can prevent droplets that carry the virus from escaping and infecting others. Meanwhile,

it can protect yourself by reducing your chances of catching the virus when you go outside.

Since the start of the coronavirus outbreak, some places have fully embraced wearing face masks. Why Asian areas embrace masks? It is not just about government directives and medical advice - it's also about culture and history. In East Asia, many people are used to wearing masks when they are sick or when it's hayfever season because it's considered impolite to be sneezing or coughing openly. The 2003 Sars virus outbreak, which affected several countries in the region, also drove the importance of wearing masks. We have experienced contagion before - and the memories are still fresh and painful.

Wearing Masks Are Effective At Slowing COVID-19 Spread

In the Czech Republic and Slovakia - wearing face masks it's now compulsory.

Wearing Masks Already Working In The Czech Republic

People should be strictly warned that wearing a face covering doesn’t let you ignore social distancing rules. Exactly the opposite, mask wearing, as a very visual reminder of the dangers of the virus, could actually act as a "behavioural nudge" to you and others for overall better personal hygiene.

Putting on a mask every day before you go out is like a ritual, like putting on a uniform, and in ritual behaviour you feel you have to live up to what the uniform stands for, which is more hygienic behaviour like not touching your face or avoiding crowded places and social distancing.

Mask management

If medical masks are worn, appropriate use and disposal are
essential to ensure they are effective and to avoid any increase
in transmission.
The following information on the correct use of medical
masks is derived from practices in health care settings:

  • 1. Place the mask carefully, ensuring it covers the mouth and nose, and tie it securely to minimize any gaps between the face and the mask.
  • 2. Avoid touching the mask while wearing it.
  • 3. Remove the mask using the appropriate technique: do not touch the front of the mask but untie it from behind.
  • 4. After removal or whenever a used mask is inadvertently touched, clean hands using an alcohol-based hand rub or soap and water if hands are visibly dirty.
  • 5. Replace masks as soon as they become damp with a new clean, dry mask.
  • 6. Do not re-use single-use masks.
  • 7. Discard single-use masks after each use and dispose of them immediately upon removal.
Cloth (e.g. cotton or gauze) masks are not recommended under any circumstances.

Finally, I hope the information above will give

you some ideas to stay healthy and safe in this critical moment.
