Close skin-to-skin contact, cuts or abrasions, contaminated objects and surfaces, crowded living conditions, and poor hygiene are all factors that have been associated with the spread of MRSA. Also, people in locations where these factors are common such as gyms, dormitories, military facilities, households, prisons, and daycare centers may have an increased risk of acquiring a MRSA infection.
MRSA is found on people and can get on objects and surfaces outside the body when infected skin or certain areas of the body where these bacteria can live such as the nose come into contact an object or surface. You will not automatically get MRSA if you touch a surface that has MRSA on it. However, MRSA is more likely to cause problems when you have a cut or scrape that is not covered. MRSA can also get into small openings in the skin including openings at hair follicles. The best defense is good hygiene which will decrease your risk.
MRSA can spread in healthcare settings from patient to patient when healthcare personnel do not use proper hygiene or through the improper use of equipment. Since healthcare settings can leave patients vulnerable to MRSA, it is essential for healthcare workers to utilize proper hand hygiene such as washing with soap and water or using an alcohol-based hand rub.
