Staph infection, also known as MRSA, is a bacterium that causes boils and legions to the skin. Usually, it is passed from person to person by the hands. In addition, open wounds and cuts can be contaminated easily and poor health and living in overcrowded conditions can contribute to the infection being passed on. Practicing good hygiene can reduce the likelihood of your getting staph infections or a recurrence. This involves washing the hands frequently and also using hand-sanitizers.
