Boils on Back Pictures - 7 Photos & Images

Boils are generally caused by an infection of the hair follicles by Staphylococcus aureus or staph. Staphylococcus bacteria are often found in the nose and throat. The bacteria can also be transmitted via contact with an infected person or an infected article, such as a washcloth or towel. In most cases, however, people who come in contact with the bacteria do not get boils. Bacteria continue to grow while producing substances that invade surrounding cells.

Common causes and risk factors of Boils:
An infection of the hair follicles by Staphylococcus aureus or staph.
Diseases, such as hypogammaglobulinemia.
Poor hygiene or malnutrition.
Medications used for cancer chemotherapy.
