Most cases of Coronavirus are mild and get better without medical attention. About 15-20% of people become more seriously ill, and the death rate is about 2.5%. If you are young and healthy, your risk of getting seriously ill seems to be lower.
The fatality rate of Corvid-19 is much lower than SARS or MERS- which is obviously good news. However, it's still quite a bit higher than the flu, and it's also possible the death rate could go up in countries with more elderly people, and also in countries where people don't have access to medical care.
