These bacteria can live harmlessly on many skin surfaces, especially around the nose, mouth, genitals, and anus. But when the skin is punctured or broken, staph bacteria can enter the wound and cause an infection.
Usually causes skin infections that are limited to a small area of a person's skin, and can also release toxins (poisons) that may lead to illnesses like food poisoning.
What Causes Staph Infections?
People can get staph infections from contaminated objects, but staph bacteria often spread through skin-to-skin contact — the bacteria can be spread from one area of the body to another if someone touches the infected area.
Staph infections can spread from person to person in group living situations. Usually this happens when people with skin infections share personal things like bed linens, towels, or clothing.
Warm, humid environments can contribute to staph infections, so excessive sweating can increase someone's chances of developing an infection. People with skin problems like burns or eczema may be more likely to get staph skin infections.
