What are they?
There are many different types of rashes, which can broadly be divided into two types: infectious and non-infectious. Non-infectious rashes include eczema, rosacea, hives and dermatitis. Infectious rashes include ringworm, impetigo, scabies and shingles.
Who gets them?
Most people will develop some type of rash at some point in their life. Infectious rashes like impetigo are more common among children.
What causes them?
Itchy rashes like contact dermatitis and allergic dermatitis are often caused by environmental irritants or allergens. Infectious rashes like impetigo and shingles are caused by bacteria.
What are the symptoms?
Contact dermatitis commonly affects the hands and face. Skin may become red, blistered, dry, scaly, cracked and itchy. Rashes which are caused by an allergy will usually develop within a few hours of exposure. Shingles, which causes painful, itchy blisters, is caused by the chickenpox virus and impetigo sometimes develops after bacteria enters the skin where it has been damaged by a cut, insect bite or eczema.
What are the best treatments?
The most important thing is to get a correct diagnosis from an expert. Infectious rashes often get better without treatment, but antibiotic cream or tablets may be needed. Non-infections rashes can be prevented or relived if you avoid known irritants, and use moisturisers and topical creams to keep the skin supple and relieve itching.
