###Human: What is the skin rash that itch sometimes in a child? ###Assistant: Hi. I have seen your query and examined your given pictures (attachment removed to protect patient identity). It seems your son has a hand, foot, and mouth disease, and does not look like impetigo. HFMD (hand, foot, and mouth disease) is a viral infection caused by the coxsackie virus. It is a self-limiting disease and takes around 5 to 7 days to subside. Symptomatic treatment can be taken like topical Lactocalamine lotion local application twice daily and Orasep (Chlorhexidine gluconate) mouth gel local application twice for five days after consulting your gp or near by dermatologist,
