Children with scarlet fever need to be isolated in time. Usually, it takes 3 weeks of isolation treatment before they can recover, and they can go to school only after they have fully recovered. Scarlet fever is a respiratory infectious disease that is highly contagious and can be spread through airborne droplets in close proximity, so it requires isolation treatment. Children with scarlet fever usually have fever, rash and other symptoms, which can be effectively treated with regular and rational use of sensitive antibiotics. Therefore, once the diagnosis of scarlet fever is confirmed, it is recommended to isolate the child until 7-10 days after regular antibiotic treatment. After the fever has subsided, the child should undergo routine blood tests and bacterial culture, and go to school only if the routine blood tests are normal and the bacterial culture is completely negative. If your child has scarlet fever, it is important to consult a pediatrician or an infectious disease department in time for isolation and treatment, and to have a light diet and reasonable care during the illness. During the recovery period of scarlet fever, furfuraceous peeling of the skin occurs, and when a few children have large patches of peeling skin, it is recommended to trim the skin with sterilized scissors instead of tearing it off, so as not to aggravate the condition.
