National geographic covers in details how coronavirus attacks the body and damages organs. I wish I had time to summarize it all.
But the very short summary :
- It's more like SARS/MERS. After attack in lung, it damages the tissue. Body's immune system jumps in, and makes more damage due to it's hyper activity. Even if one survives then, they live with damaged lung.
- Then there's "cytokine storm". Body bleeds. Lung fills with blood. Resulting into less Oxygen supply. And leading to other organ failure.
There's more. But like any medical journal, it's all written more scarily than it needs be. :-)
I don't think we have any work learning it all. Other than watching for symptoms. And symptoms are more like AIDS, blisters on body. or Ebola, body bleeding.
