The new coronavirus pneumonia has infected infants, and in the early days when the new coronavirus was first reported, the first 27 cases were mainly employees of the Wuhan South China Seafood Market, so it was concluded that infants and children were not susceptible to the new coronavirus. However, as the number of cases gradually increased, NCCV infections occurred in people of all ages. The youngest reported infant infection is now a five-day-old baby. The small number of people infected with NIV is usually not allowed to leave the house easily, which is related to the low possibility of exposure to NIV. However, NIV is an emerging virus and is susceptible to all age groups, so it is more normal for children to become infected. Content source: Dr. Yurai
