Using available preliminary data, the median time from onset to clinical recovery for mild cases is .Although for most people COVID-19 causes only mild illness, it can make some people very ill. More rarely, the disease can be fatal. Older people, and those with pre- existing medical conditions (such as high blood pressure, heart problems or diabetes) appear to be more vulnerable..approximately 2 weeks and is 3-6 weeks for patients with severe or critical disease.The main way the disease spreads is through respiratory droplets expelled by someone who is coughing. The risk of catching COVID-19 from someone with no symptoms at all is very low. However, many people with COVID-19 experience only mild symptoms. This is particularly true at the early stages of the disease.
