Herpes in children can be caused by a variety of reasons and the recovery time is related to the type of herpes and the child’s own constitution and cannot be generalized. If the disease is caused by herpes simplex virus, such as herpes gingivostomatitis, which occurs in the mouth, tongue, gums, etc., it is self-limiting and usually has a natural course of 1-2 weeks, which may be extended to 2-3 weeks if there is secondary infection. In the case of genital herpes, the entire course is about 20 days, but usually recurrent, mostly occurring within 1-4 months after the primary herpes. In case of disease caused by varicella-zoster virus, patients may form smaller, painful yellow blisters with symptoms such as fever and general malaise after 1 day and usually recover in 7-10 days, which may be somewhat prolonged in case of complications. If a child develops herpes, it is recommended to visit the pediatric dermatology department of a regular hospital in a timely manner, where a professional doctor will examine and determine what kind of herpes it is, and then provide targeted treatment according to the specific cause.
