Rashes are a fairly common childhood occurrence because of the various new substances children come into contact with. Contact dermatitis is the clinical term denoting inflammation of the skin and is caused either due to an allergy to a chemical or irritation of the skin from initial exposure. Cleveland Clinic explains that the symptoms of rash can occur after only one exposure to the irritant or after many, depending on the child.
Exposure to Virus
Roseola is an acute condition caused by a form of herpesvirus, or HHV-6, that causes skin rash. The U.S. National Library of Medicine notes that children with roseola typically develop a rash on the limbs, neck and face between the second and fourth day from exposure. This rash is rose-colored with small raised sores and is preceded by fever and irritability in the child. Roseola is commonly spread to children in close contact, such as in a daycare setting.
Heat
Red or pink-colored dots on the skin occurring on the covered areas of the body is a symptom caused by heat rash. The Palo Alto Medical Foundation explains that babies that are dressed too warmly often cause the sweat ducts to become blocked. This leads to swelling, discomfort and itching in the covered areas. Heat rash clears up prior to four days typically, however if signs of infection exist such as pus drainage and increased swelling, medical attention is required.
Bacterial Infections
Strep and staph bacteria causes skin infections. In severe cases a contagious condition called impetigo may develop. Breaks in skin from bites or open wounds allow bacteria to enter the body and cause infection. Bacterial rashes appear like pus filled blisters, surrounded by redness and swelling the U.S. National Library of Medicine notes. MayoClinic.com explains that less severe bacterial infections such as yeast may also occur in diapered children. Warm and moist environments increase the risk of bacterial growth and short term infections of the skin. Bacterial infections are treated with antibacterial creams or antibiotics if needed.
Irritants and Sensitive Skin
Some children have sensitive skin that is easily irritated by chemicals. Irritants from new products may come in the form of lotions, perfumes or soaps. In many cases, products with fragrance cause rashes in children with sensitive skin. MayoClinic.com says that simply washing the child in scent free soap and water will alleviate the problem in mild cases of skin rash from hygiene products.
