No, I don't think that's correct. 20% of cases need hospitalisation which means oxygen therapy, isolation etc etc. Many of those will end up in HDU but the most severe will end up in ICU. Each person is going to occupy a bed for a month or more. 50% of the cases in France in ICU are in their 40s.
So, this is truly SHTF territory.
Edit: Sorry, I believe overseas they are treating all the similar severity cases in shared rooms, probably the old Nightingale style wards.
They've adopted an Ebola methodology to treat people to reduce the numbers of staff getting infected. presumably on account of high viral loads, medical staff get the most severe disease.
