The contagiousness of the new coronavirus pneumonia should not be underestimated. It is very contagious because the population is generally susceptible. The number of confirmed cases has already reached more than 10 times of the total number of confirmed cases of SARS in that year, which shows that its contagiousness is very strong and extensive, so it is more important to pay extra attention to it. The new coronavirus pneumonia has a relatively low lethality rate, but is both more infectious and pathogenic. Disease defense and control should be strengthened, including screening of infectious agents, timely control of transmission routes, and protection of susceptible populations as much as possible. Currently, there is no specific treatment for novel coronavirus pneumonia, so it is especially important to strengthen the awareness of the population. Of course, by improving one’s immunity and exercising more, even if one is infected, it is usually a mild case with a relatively low mortality rate, and the vast majority of cases can be cured on their own. The majority of cases can be cured by themselves. Clinical first-line severe cases mainly come from elderly patients, especially those with low immunity or combined underlying diseases are more likely to develop into severe cases, which may have more serious consequences after the onset of the disease.
