Children with low autoimmune function are susceptible to new coronavirus pneumonia. However, because the early cases were traders in the South China Seafood Market, the incidence in children was low. As the outbreak progressed, the patient base increased and all age groups emerged. Neocoronaviruses are newly emerged viruses and humans of all ages are susceptible, and children are no exception. Children are also susceptible to new coronaviruses because they are new, susceptible, and highly contagious, so they are contagious to people of all ages, and children are no exception. Children, in particular, are active by nature and are prone to touching and exploring, so their exposure to the new coronavirus will make them more susceptible to infection. Parents should take better care of their children and go out as little as possible. If they have to go out, they should wash their hands regularly, ventilate the house, and let their children strengthen their nutrition, live a regular life, and go to bed on time, which can improve their immunity and reduce the chances of infection by the new coronavirus.
