Carbuncle is a cluster of boils that are connected to each other. Boils are painful, pus-filled, red bumps that form onto the skin due to bacterial infection. They originate at the hair follicles due to inflammation caused by bacteria.
Boils usually occur on the hairy areas of the body, especially on the face, neck, armpits, buttocks and thighs. They grow larger until they rupture to drain the pus, at times leaving behind a scar. Carbuncle is caused by the bacteria, Staphylococcus Aureus, which is commonly found on the skin and inside the nose. It may also develop on a cut in the skin, providing easy passage for the bacteria to enter.
Normal healthy people can get affected by carbuncle, but certain risk factors increase the chances of contracting the disease. These include close contact with someone with boils, weakened immunity, chronic skin conditions that damage the skin’s protective barrier, diabetes and overall poor hygiene and health.
