A problematic false Italian friend

For some reason I’ve been reading a lot of Italian epidemiology reports lately, and my Italian isn’t very good. So I found myself at first assuming that counts of “ricoverati” cases were those who had recovered. And that made it really confusing that this document estimates the median time from “ricovero in ospedale” to death (4 days). I had to look it up to discover that ricovero actually means hospitalised (and more generally, sheltered).
