Hmm considering he's on antibiotics it's bacterial pneumonia. Could be Hospital-acquired pneumonia an infection of the lungs that occurs during a hospital stay.

Seeing as though he was also apparently 260 pounds, doesn't seem to be the healthiest guy by any standards.

from a 2006 article:

Patients in the intensive care unit (ICU) are at risk for dying not only from their critical illness but also from secondary processes such as nosocomial infection. Pneumonia is the second most common nosocomial infection in critically ill patients, affecting 27% of all critically ill patients. Eighty-six percent of nosocomial pneumonias are associated with mechanical ventilation and are termed ventilator-associated pneumonia (VAP). Between 250,000 and 300,000 cases per year occur in the United States alone, which is an incidence rate of 5 to 10 cases per 1,000 hospital admissions. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1592694/

Without knowing the details of his initial covid19 illness and how it was treated before he was sent to ICU it's not fair to comment on his particular experience. The msm have of course gone full retard with this, figuratively kicking someone when they're down and publicly shaming them without know all the facts. That he had his experience and while older people breeze through illnesses like one of my 80+ year-old family members (who didn't go to hospital) suggests there's more to this.

He fucked around and found out.
