What are the symptoms of impetigo in children?

Symptoms of impetigo in children include small, red spots on the skin that develop into blisters that break open, according to WebMD. The sores are typically itchy, develop a crusty exterior and ooze fluid. Most children do not experience pain with impetigo sores, but the sores can increase in number and size.

Impetigo is common among children age two to six and produces sores and blisters on the hands, neck, face and diaper area, according to KidsHealth. The condition is contagious, yet children with skin problems, cuts, scrapes or insect bites are more at risk for developing impetigo. It is possible for children with healthy skin to develop the condition, though.

Impetigo is caused by streptococcus and staphylococcus bacteria, explains WebMD. The bacteria usually enter the body through cuts, scrapes or existing sores on the skin. The condition is diagnosed during a physical exam by a medical professional and through lab tests to determine the type of bacteria that has affected the skin. Most cases of impetigo are treated with oral antibiotics or an antibiotic ointment or cream applied directly to the sores on the skin. Most children heal from impetigo within one week, but the condition is no longer contagious 24 hours after treatment begins.
