Bear in mind that the case fatality rate may actually rise going forward if draconian containment measures are not taken. This virus is very transmittable, and viral shedding is nearly as high in asymptomatic infected people as in those who are visibly sick. People can be walking around infecting others for weeks without knowing they are sick themselves. Based on the data we have, somewhere between 13-20% of infected people will require hospitalization, usually in the second or third week, which will very quickly will overwhelm hospital capacity, especially considering hospitals are already near capacity from the flu. Worse, coronavirus cases that progress to the pneumonia stage often require weeks of oxygen, assisted ventilation and other intensive care. Some patients appear to develop fibrosis, so basically permanent lung damage. There simply isn't enough capacity for the number of people who will likely need this therapy in the coming months. This will lead to deaths in people of all ages; obviously the rate will be higher in the elderly (which is somewhere around 15% for those above 80) and people with existing health complications, diabetes, smokers, cancer etc. etc. (of which there are millions), but there have been plenty of cases of young, healthy people dying from multiple organ failure from cytokine storms. Basically overly aggressive immune response causes massive inflammation and floods the lungs with fluid. Same thing happened in the young in 1918. The other thing to consider regarding the case fatality rate is that dividing deaths by confirmed cases may not be the best metric. Deaths/recoveries may be a better method, as it captures cases where the disease has completely run its course. Based on data so far, that would put SARS-COVID19 around 6-8%, not too far out of line with SARS' 10%. Don't expect this to disappear from the headlines anytime soon. We likely have not seen an infectious disease threat of this magnitude in a century.
