The population generally lacks immunity to novel coronavirus, and when a child has been in contact with a suspected case, intensive observation should be made. If there is fever, malaise and dry cough, parents must take their children to the hospital promptly to determine if the pneumonia is a novel coronavirus infection. If it is suspected or confirmed, go to a designated hospital with effective isolation and protection. If it is not pneumonia due to novel coronavirus infection, you should do your daily protection, such as washing hands carefully before and after meals, minimizing going out, and wearing a mask if you must go out. Pay attention to proper nutrition to improve your child’s ability to fight disease and reduce the risk of infection.
