Overview of skin infections
Ngā Whakapokenga Kiri
Skin infections are common in people of all ages. They can be caused by viruses or bacteria (germs).
There are many types of skin infection. Many of them are mild and easily managed but some can be severe. Some of the more common types of skin infection are cellulitis, impetigo, scabies, Staphylococcus and MRSA.
A skin infection often starts when the skin is broken. Common causes of broken skin include a minor bite, graze, sting or burn. Skin conditions such as psoriasis, atopic eczema and dermatitis can also lead to broken skin.
If not treated, a skin infection can lead to more serious health problems, sometimes needing time in hospital.
How can I reduce the risk of getting a skin infection?
You can reduce the risk of a skin infection by taking simple steps.
- Practise good hand hygiene. Wash your hands often with ordinary soap and water; you don't need to use a special antibacterial soap. If you have dry or sensitive skin, you can use a soap substitute such as aqueous cream or any cleanser that has a pH level of 5.5. You can also use an alcohol-based hand sanitiser. Ask your pharmacist if you need advice.
- Cut your nails short. This helps with hygiene and can stop you causing further damage by scratching wounds or itchy skin.
- Moisturise dry skin to help stop your skin cracking.
- Cover all sores, cuts, or wounds with a plaster. Supermarket plasters are fine to use.
- Avoid sunburn as sunburn can cause skin damage, which can lead to a skin infection.
- Don't share personal items such as bedding, towels or clothing with anyone who has a wound or skin infection.
When and where should I seek help?
See your GP if you have a fever or if you notice a sore or area of redness that:
- is larger than a 10-cent coin
- is red, swollen and getting bigger
- has pus (yellow liquid)
- has red streaks coming from it
- is not getter better after two days
- is anywhere near your eyes.
