I don't know which 'medical experts think this, the WHO are saying most people get a fever and dry cough.Medical experts think most people went even know they've had it, it can be that mild. Can't believe the scaremongering going on over this, check out how many people died of flu in the US alone on 2018, didn't hear of any flights cancelled or food shortages. 13k died in the UK in 2008 and not a peep. The biggest threat with this are the idiots panicking over something that happens every winter.
This does not appear to be what happens every winter it is a new virus with an unknown outcome that appears to have a far higher mortality than seasonal flu.
