I guess, sitting in our "comfort zone" it is hard to imagine the hospitals with hundreds of people needing beds and the frenzied staff. Apparently, the symptoms are debilitating - these people are very sick, and the staff no doubt very scared knowing that medical staff have already died from it. Perhaps the hospitals are understaffed with people not turning up for work etc etc.
The percentage of people dying is small, but there are thousands of sick people needing treatment and isolation, and still a lot of answered questions about the virus and how it is spread.
