Yes and no, if someone recently had organ transplant it is almost a certainty you can add him to the list as he would be on drugs to suppress the immune system, at least two such cases in Korea.
It also would depend what previous illness, age...
The other day a 101 year old recovered, 96 year old recovered, a 73 another 100....
Yeah, the immune system. All depends on how strong the person is to fight it just like other pandemics.
Korea is claiming to test 40k people per day and the discussion is going on in US too. Italy has turned into a prison. The videos are disturbing where they are dragging people by force if they have slight fever. They are treating them like street animals
