Over 60 per cent people who have been cured of the coronavirus have complained of severe breathing issues even after recovering from the infection. Allying all concerns, the medical experts said it was normal to have some respiratory problem as coronavirus affects lungs the most. The lungs will gradually start functioning normally, they assured.

Hamidia Hospital Medical Superintendent Dr ID Chaurasia, explained that Covid-19 directly impacts the lungs and damages the alveoli (tiny air sacs). The function of the alveolus is to transfer oxygen to the blood vessels. These blood vessels or capillaries carry the oxygen to the RBCs (Red blood cells). It is the RBCs that finally deliver the oxygen to all the internal organs in the body.

The virus works by damaging the wall and the lining of the alveolus and capillaries. The debris from the damage, which is plasma protein accumulates on the alveolus wall and thickens the lining. As the walls’ thicken, the transfer of oxygen to the red blood cells is impaired. The thicker the wall gets, the more difficult it gets to transfer oxygen to the red blood cells, which causes difficulty in breathing as the body is running short of oxygen. And the lack of oxygen to the internal organs results in a deficit in the body and impairs the functioning of the organs. At this juncture, the body fights to increase oxygen intake.

And the first response of the body is to destroy the virus and prevent its replication, but if the individual has weaker immunity then the body is unable to stop the virus, and this aggravates the crisis.

Similarly, other factors  that lead to fatality include underlying illnesses (hypertension, diabetes, cardiac problems, respiratory issues) and individuals who are on immune-suppressing medications. In older individuals, the risk is higher, as the immunity decreases with age and they have a higher disposition for other illnesses.
