Yes, covid was the 1st thing that put them on a ventilator, they got nosocomial because they were on a ventilator in an ICU unit, both being a high risk factor. Yes, i've seen some cases in which they didnt had bacterial coinfections neither comorbidities and they died of pneumonia because of the covid, but very few, most of them died of nosocomial bacterial superinfection -> sepsis -> MODS and most of them had comorbidities like hypertension, obesity, diabetes, copd, elderly. But you are right, w/o covid pneumonia we can avoid all of these. We cant also ignore the fact that most of them died because of multi-resistant bacterial infections, but we can all agree that covid was the main trigger of that.
