Clear blisters on children’s bodies are mostly seen in chickenpox, but not all blisters are necessarily chickenpox. This is because in addition to chickenpox, clear blisters can appear in hand, foot and mouth disease, shingles, allergic diseases, and mosquito bites. At this point, it is important to identify the child based on the symptoms he or she exhibits, exposure history, epidemiology and whether he or she has been exposed to special items, eat any special allergy-prone foods or take allergy medications. It is important to go to the pediatric department or the infectious disease department of a regular hospital as soon as possible for relevant tests, such as pathogenic tests, to clarify the cause of the disease. To determine whether it is chicken pox, hand, foot and mouth disease or other causes of clear blisters, to take different treatment plans.
