Consulting a medical professional is the most conclusive way to diagnose a child's rash. There are numerous online resources that can guide in this process as well. Some common skin rashes in children include ringworm, fifth disease, chicken pox and impetigo, reports WebMD. Some children experience other conditions that cause rashes, such as heat rash, contact dermatitis, hand-foot-mouth disease and eczema.

A fungus that thrives off dead skin, hair and nail tissue causes ringworm, explains WebMD. Beginning as a red, scaly patch or red bump, it evolves to include an itchy, red ring with raised, blistered borders. Ringworm is spread through direct skin-to-skin contact, as well as shared accessories, and is treated with an antifungal cream.

Beginning with flu-like symptoms, fifth disease progresses to cause a bright red face and body rash, notes WebMD. Spread by coughing and sneezing, it tends to last two weeks and is treated with rest and pain relievers. It is important to avoid aspirin during this time, and to seek medical care if a person is pregnant around someone with fifth disease.

Causing itchy, red spots all over the body, chicken pox first blisters, then bursts, dries and crusts over, according to WebMD. It is highly contagious and can lead to serious complications, especially in elderly adults and people who have not been vaccinated or who have not had the disease before.
