Boil: Introduction. A boil is a large infection of a hair follicle, the tiny opening in the skin from which a hair grows. Boils are due to an invasion of bacteria that enter the follicle and cause a bacterial infection of the follicle and nearby skin. Boils are also called skin abscesses or furuncles.
Cause. The most common cause of boils is staphylococcus aureus bacteria entering a hair follicle of the skin. If your child has a scrape or cut, it damages the hair follicle, then the bacteria can enter deeper into the epidermis.y the time your childâs boil has finished filling with pus, it can be as large as a golf ball. The boil often oozes fluid. As the boil drains, the pain subsides and the size shrinks. The areas most commonly affected by boils are the face, armpits, buttocks, thigh and armpits.
