The recent outbreak of the pandemic ‘coronavirus’  popularly know as COVID-19.

Current evidence suggests that transmission of coronavirus occurs primarily between people through direct, indirect, or close contact with infected people through infected secretions such as saliva and respiratory secretions, or through their respiratory droplets, which are expelled when an infected person coughs, sneezes, talks or sings.

So nose mask has been made compulsory since then so as to help curb the virus

However alot of people are not used to wearing nose mask, wrong use of it can lead to  suffocation.

It is necessary that you pull down the nose mask away from your nose at least every 1 hour interval when you're outside.
