Know how aerosols can damage our lungs

We need to realise that to what extent our lungs may get affected by aerosols

It is remarkably vital for all of us to keep our nose covered all the time as we know that infections, germs and bacteria travel through the air. A good mask provides protection to some extent.
As per new research, severe infection is caused in the lung cells when we inhale isolated coronavirus particles.
These viruses reach out to 65% of the deepest corners of our lungs. That leads to damage, and this damage further leads to low blood oxygen levels.
A study at the University of Technology, Sydney, found that more of the aerosols reach the right lung than the left.
Due to the highly asymmetrical anatomical structure of the lung and the way air flows through the different lobes, the particles get deposited in the right lung.
Earlier researches revealed that virus aerosols travelled through the nose, mouth and throat and reached the lower lungs.

Depending upon our breathing rate, between 32 to 35% of viral particles is deposited in these first 17 branches. Around 65% of the virus reaches the alveoli or the air sacs in our lungs.
Due to the highly asymmetrical anatomical structure of the lung and the way air flows through the different lobes, the particles get deposited in the right lung.
A CT Scan of a Covid-19 patient showed similar instances.
The World Health Organization recently updated its advice about the importance of aerosol transmission, warning that because aerosols can remain suspended in the air, crowded indoor settings, areas with poor ventilation are risky for the transmission of Covid-19.
