Patient: Description of the condition (onset time, main symptoms, hospital visited, etc.): 7.17 in Tianjin Children’s Hospital diagnosed as hand, foot and mouth, and then repeated, after the isolation period, body temperature sometimes 36.5, sometimes 37.1, sometimes to 37.4, is this normal? After treatment with infusion, the fever was reduced. After the isolation period, the body temperature was 36.5, 37.1 and sometimes 37.4, is this normal? Yang Song, Department of Pediatrics, Beijing Ditan Hospital: First of all, HFMD can be repeatedly infected because there are many intestinal viruses that cause HFMD and there is no cross-immunity among them, therefore, prevention is important. Pediatric body temperature is generally a little higher than that of adults, and is closely related to feeding, activity, environment, etc. It is not important that the child is in good spirits, eating and sleeping well, and has a slightly higher body temperature? Patient: Thank you doctor
