Define furuncle
The Correct Answer and Explanation is :
A furuncle, also known as a boil, is a painful, swollen, red, and infected area of the skin that forms around a hair follicle. It typically contains pus and is caused by a bacterial infection, usually by Staphylococcus aureus. Furuncles are often found in areas where friction or sweating is common, such as the neck, armpits, buttocks, and thighs.
Explanation:
A furuncle begins when a hair follicle becomes infected with bacteria, leading to inflammation. The infection causes the body to send immune cells to the site, resulting in the accumulation of pus. The swelling can become larger as the body tries to fight the infection, and a collection of pus may form at the center of the boil. Over time, the boil may rupture and drain the pus, leading to relief from pain and pressure.
Risk factors for developing a furuncle include poor hygiene, obesity, excessive sweating, and skin irritation. People with diabetes, weakened immune systems, or chronic conditions may also be more prone to furuncles. Close contact with infected individuals can also increase the risk, as the bacteria that cause furuncles are contagious.
Treatment for a furuncle typically includes warm compresses to help the boil drain naturally. In some cases, a healthcare provider may need to incise and drain the furuncle if it doesn’t drain on its own. Antibiotics may be prescribed if the infection spreads or if there are signs of complications, such as cellulitis or an abscess. In severe cases, or when a person experiences recurrent furuncles, a healthcare provider may investigate the underlying cause, such as a bacterial carrier state or other health conditions.
Prevention involves maintaining good personal hygiene, using antibacterial soaps, and avoiding sharing personal items like towels or razors. If a furuncle forms, it is essential to avoid squeezing it, as this can spread the infection or cause additional complications.
