At the moment they think at worse (at worse) it will have a 2% death rate far less than SARS and Ebola. It’s also hitting mainly elderly patients the hardest and those who are immune compromised much like the flu.
I think it could be worse than swine flu (which I got as it happens) in that many people could get it and cause issues such as less workforce and school shutdown etc.
My experience with swine flu was 2 weeks of feeling awful truly awful then 6 weeks more to properly recover. I think this could be similar worse than a cold and on a par with flu as to how it makes you feel
