There is another possibility to consider. What if the severe effects we are seeing is because of reinfection?
“Reinfection” to the same virus would be very unusual. If these patients are experiencing pulmonary problems shortly after “recovering” from coronavirus, suspect their damaged, weakened lungs are susceptible to another pathogen possibly a bacteria.
The problem is that scientists and physicians are not being allowed into China to make independent, apolitical evaluations. Nor are the Chinese being honest with their pronouncements.

Viruses are notorious for infecting a host and then retreating and reemerging at a later time when the host’s immunity is weakened. One of the most common is the Chicken Pox virus that can reemerge years later as Shingles. While this virus lurks in the nervous system, apparently COV-19 may hide out in the respiratory and circulatory systems. As with Shingles, when the virus reemerges its effect can be worse than the original infection. This is why I question whether those who are presumed “recovered” are ever truly free of the virus. Let’s hope that when COV-19 reemerges, though possibly lethal the second time around for the host, is not transmissible, which apparently is the case with Shingles.
