Infection is one of the commonest reasons for people to consult their family doctor or pharmacist about a skin problem. There are many causes of skin infections – for example, impetigo is a very common problem caused by bacteria called staphylococcus aureus. Impetigo usually results in sore, red and crusted patches of skin, often on the face but it can occur elsewhere.
Skin infections can also arise from viral infections such as cold sores that are caused by the herpes virus. Fungal skin infections are common as well – examples include athlete’s foot and candidiasis (thrush). There are many different types of common and rare skin infections – if you are concerned, it is sensible to seek advice from a healthcare professional, both to confirm whether you have a skin infection and to advise about how to best treat it.
