New coronavirus pneumonia, which is classified as a category B infectious disease, is being managed as a category A infectious disease. I am here in Hankou, Wuhan, which is the most affected area by the new coronavirus pneumonia, to talk about how to protect children at this stage. The outbreak in Wuhan is so serious that on January 23, a decision was made to stop all public transportation and close the city. Everyone was urged to stay home for New Year’s Eve and to minimize going out and visiting friends and relatives. There are three elements in the spread of infectious diseases: the source of infection, susceptible populations, and transmission routes. The source of infection: the obvious ones are the patients who have developed the disease, the friends and relatives who are in contact with these patients, and most importantly, the source of infection is the people who are occultly infected. Occult infection refers to those who have strong body resistance, infected with the source of the disease but no symptoms, and they do not know it themselves, in fact, this is the most dangerous source of infection. Susceptible people: All of us are susceptible to this RNA coronavirus, which means there is no specific immunity. Unlike children who are vaccinated against measles, their susceptibility to measles is significantly reduced, and those who are vaccinated against polio have a significantly reduced susceptibility to polio. Patients who have suffered from mumps and chickenpox will not suffer from similar diseases again. Transmission route: The connection between the source of infection and the susceptible population is called the transmission route. Only a susceptible person who comes in contact with the source of the infection can cause the disease as an idiosyncratic disease. What to do in the face of an outbreak? For the source of the infection, the cases that have been diagnosed, now by the streets, districts and hospitals and doctors from all over the country, in the hospital management of such patients, and to ensure that they will be allowed to return home only after the quarantine period, all these work is done by medical workers. The general public can only cheer them on in this area, only find ways to help them and do something to ensure the supply of protective supplies. For the means of transmission, we are now closing the city, stopping all public transportation, calling on people to spend the New Year at home, stopping visits to friends and relatives. Measures such as restricting motor vehicles on the roads are cutting off the pathways of infection. On this one, we listen to the government’s call and just follow the implementation. What we parents can do now is to work on the susceptible people, that is, to maintain the baby’s good resistance to disease or improve resistance to disease so that babies try to avoid disease eat well, sleep well, maintain the original habits and routine. Care as far as possible not to get cold, not heat, do not catch a cold, open the windows and doors every day for ventilation. Eat well is very important, especially to ensure that the diet of protein egg supplementation, infants and young children’s protein needs are daily for 2.5 to 3 grams per kilogram of body weight per day, eggs, fish, shrimp, pork, beef, mutton, chicken are protein-containing. It is important to have a balanced diet of nutrition. Patients with underlying diseases, such as anemia, rickets with vitamin D deficiency, congenital heart disease, immunodeficiency, patients undergoing chemotherapy, etc., should pay special attention to cut off the route of infection and protect their children. We do not need to panic and anxiety, panic and anxiety will reduce the ability to resist disease, improve and maintain the ability to resist disease is to rely on their own, then the baby’s ability to resist disease is to improve the parents.
