Masks for Curbing – SARS-CoV2 Coronavirus

Masks for Curbing – SARS-CoV2 Coronavirus

COVID-19 virus spreads easily from person to person contact. Virus carrying droplets dry fast enough to form droplet nuclei and remain airborne eventually landing on different surfaces.

SARS-CoV-2, the virus that causes COVID-19, has been detected in aerosols for up to three hours and on plastic and stainless steel surfaces for up to three days. (N.Engl J.Med. 2020).

Why Wear a Mask?

Masks lower the chances of coronavirus entering the respiratory system through droplets still in the air from an infected person. Reducing the chances of inhaling the virus by wearing a protective mask that is cleaned thoroughly using a combination of approaches that use Heat, UV light, water, soap and alcohol, will be vital to stopping its spread.

World Health Oragnization (WHO)  – Masks are effective only when used in combination with frequent hand-cleaning with alcohol-based hand rub or soap and water. If you wear a mask, then you must know how to use it and dispose of it properly.

Types of Masks

  • N95 Masks: These respiratory masks are widely being used right now to lessen the spread of coronavirus.  These are slightly more tight-fitted.
