Full Answer

Chickenpox is a rash consisting of pus-filled blisters that covers the entire body, notes Medline Plus. It typically occurs in children 12 and under, who get an average of 250 to 500 blisters. Children with pre-existing skin conditions, such as eczema, can get twice as many blisters. Adults also get the infection, and their symptoms tend to be more acute. The severe itching caused by chickenpox can result in scarring if the blisters are scratched and become infected.

Hives and contact dermatitis can be caused by allergens or other irritants, according to Everyday Health. Hives develop suddenly, causing raised, itchy welts on the skin. They usually result from a food or medication allergy and improve with antihistamines. Contact dermatitis is a rash consisting of itchy bumps, blisters, scales or inflammation, and it generally develops after contact with an irritant. Poison oak, poison ivy and chemicals are some of the irritants that cause this condition.

Often found in diabetics and overweight people, intertrigo appears in skin folds as a red or brown rash that itches and oozes due to chafing, observes Everyday Health. Common among allergy sufferers, eczema presents as red skin that is itchy and scaly, while impetigo develops from bacteria on the skin and presents as red blisters that ooze and scab over, according to Medline Plus.
