Neocoronavirus infections generally take 1 to 2 weeks to clear up in mild and asymptomatic infections, and 2 to 4 weeks or longer in severe cases. If the infection is mild and asymptomatic, it is also the main infected population. In general, they will be centrally isolated, and within 1~2 weeks, most of them can be cured through rest and Chinese medicine-assisted treatment, and the nucleic acid test will become negative. However, in the case of seriously infected people, especially the elderly and other people with weakened immunity and combined underlying diseases, they need to be admitted to a designated hospital for intensive treatment or transferred to ICU for treatment. It usually takes 2 to 4 weeks or even longer, with no fixed duration.
