What causes a carbuncle?
A carbuncle develops when multiple hair follicles become infected by bacteria or fungus from the skin. Staphylococcus aureus is the type of bacteria most commonly associated with boils and carbuncles. The presence of infection draws in white blood cells from the body’s immune system to combat the infection. However, if the infection does not resolve quickly, pockets of bacteria, dead cells and fluids can develop, resulting in the formation of a carbuncle. The infection that causes carbuncles can be contagious; therefore, care should be taken to limit the spread of the infection.
What are the risk factors for a carbuncle?
A number of factors increase the risk of developing carbuncles. Not all people with risk factors will get carbuncles. Risk factors for carbuncles include:
- Conditions that weaken the immune system, such as immunosuppressant drugs used in chemotherapy
- Dermatomyositis (condition characterized by muscle inflammation and skin rash)
- Diabetes (chronic disease that affects your body’s ability to use sugar for energy)
- Eczema (skin inflammation)
- Overall poor health
- Poor hygiene
- Skin damage caused by abrasive rubbing
Reducing your risk of carbuncles
You may be able to lower your risk of carbuncles by:
- Avoiding direct contact with infected areas on other people
- Maintaining good general health and skin hygiene practices
