A mere scratching of your chin could be fatal.
One of the best reasons to wear a mask is to remind you: hands off.
Please keep your hands off your face!

The virus enters the lungs and travels to the smallest parts of the lungs, tiny lung sacs called the alveoli where oxygen exchange takes place

Corona virus invades the cells of the alveoli by using its spike glycoproteins. These spike proteins attach to the cell membrane and the virus can then enter the cell.

The virus replicates and invades more cells of the alveoli
As COVID-19 causes inflammation of the the lungs, infected fluid fills the lungs thus disrupting gas exchange.

The infection starts in small basal segments

Advancing infection involves more lung and prevents efficient and effective gas exchange (inhalation of oxygen and expiration of carbon dioxide). When this exchange is not possible, a ventilator is necessary
