According to the current epidemiological data, the population is generally susceptible to the novel coronavirus, especially elderly people with underlying diseases, who tend to be sicker after infection. In addition, cases of infection have been found in children and infants, but the elderly are still the majority of patients. It is especially important to prevent infection. Washing hands frequently, going out less often and wearing masks in crowded places are proven preventive measures. The general public must follow expert advice and take safety precautions in order to reduce the risk of infection.
