About 14% of COVID-19 cases are severe, with an infection that affects both lungs. As the swelling gets worse, your lungs fill with fluid and debris.

If your doctor takes a CT scan of your chest, the opaque spots in your lungs look like they start to connect to each other.
In critical COVID-19 -- about 5% of total cases -- the infection can damage the walls and linings of the air sacs in your lungs. As your body tries to fight it, your lungs become more inflamed and fill with fluid. This can make it harder for them to swap oxygen and carbon dioxide.
You might have severe pneumonia oracute respiratory distress syndrome(ARDS). In the most critical cases, your lungs need help from a machine called a ventilator to do their job.
There’s evidence that 20-30% of the critically ill patients can develop clots in the lungs, heart, brain and legs, some of which are life threatening.
It can take time to feel better after you have pneumonia. You may feel moretiredthan usual for a while. You might also find that you can’texerciselike you used to.
Some people had a cough even after they recovered from COVID-19. Others had scarring in their lungs. Doctors are still studying whether these effects are permanent or might heal over time. A few people have even needed lung transplants because of severe tissue damage from COVID-19.
