In one month, corona virus has resulted in:
> 12,000 cases, numbers still climbing exponentially.
> 260 confirmed deaths, numbers still climbing exponentially.
> 20,000,000 people under military quarantine.
> 1.4 billion people with their movements restricted by law.
> Confirmed cases on four continents (UK's are Chinese tourists, but Japan has got cases in people that have never been to China).
Corona's R0 (Reproduction rate, the number of people each case will infect if nobody acts) is about 2.5, worse than Ebola and SARS. The fatality rate so far is 2%, and that's with medical treatment. For comparison, measles death rate with treatment is 0.1%, without treatment it's 1%.
So, it's currently rather bad.
However, has shared DNA information more quickly than it did with SARS, and the first stages of vaccine manufacture has happened in record time; at least one lab is already in the first testing stages of a working vaccine. If everything else goes according to plan, it will be ready to use in the field by the Summer.
