Does anyone have any idea / info on what proportion of the infected cases are getting Covid19 inside hospitals?
(Epistemic status: low, but I didin't find any research on that, so the hypothesis deserves a bit more of attention)
1. Nosocomial infections are serious business. Hospitals are basically big buildings full of dying people and the stressed personel who goes from one bed to another try to avoid it. Throw a deadly and very contagious virus in it, and it becomes a slaughterhouse.
2. Previous coronavirus were rapidly spread in hospitals and other care units. That made South East Asia kinda prepared for possibly similar epidemics (maybe I'm wrong, but in news their medical staff is always in Hazmat suits, unlike most Health workers in the West). Maybe this is a neglected point in the successful approach in South East Asia?
3. I know hospitals have serious protocols to avoid it... but it takes only a few careless cleaning staff, or a patient's relatives going to cafeteria, or a badly designed airflow, to ruin everything. Just one Hospital chain in Brazil concentrates most of deaths in Sao Paulo, and 40% of the total national.
Did anyone see the spread of Covid through nursing homes coming before? It seems quite obvious in hindsight - yet, I didn't even mention it above. Some countries report almost half of the deaths from those environments.
(Would it have made any difference? I mean, would people have emphasized patient safety, etc.? I think it's implausible, but has anyone tested if this isn't just some statistical effect, due to the concentration of old-aged people, with chronic diseases?)
