Boils are caused by a bacterial infection, primarily by Staphylococcus aureus, which is commonly found on the skin and inside the nose. The infection begins in a hair follicle or oil gland, leading to the formation of a painful, pus-filled bump under the skin. Factors such as cuts, abrasions, scratches, diabetes, a weakened immune system, poor hygiene, and poor nutrition can make a person more susceptible to developing boils. Boils can occur anywhere on the body, but they are most common in areas where there is hair, sweat, or friction, such as the face, neck, armpits, shoulders, back, and buttocks. Good home care can help in treating boils, but severe or recurring cases may require medical attention.
In summary, boils are primarily caused by a bacterial infection, particularly Staphylococcus aureus, and can be influenced by various factors such as cuts, diabetes, and poor hygiene. Good home care is important for treatment, and severe or recurring cases may require medical attention.
