According to the Mayo Clinic, Methicillin-resistant Staphylococcus aureus (MRSA) infection is caused by Staphylococcus aureus bacteria — often called “staph.” Decades ago, a strain of staph emerged in hospitals that was resistant to the broad-spectrum antibiotics commonly used to treat it. Dubbed methicillin-resistant Staphylococcus aureus (MRSA), it was one of the first germs to outwit all but the most powerful drugs. MRSA infection can be fatal.
Staph bacteria are normally found on the skin or in the nose of about one-third of the population. If you have staph on your skin or in your nose but aren’t sick, you are said to be “colonized” but not infected with MRSA. Healthy people can be colonized with MRSA and have no ill effects, however, they can pass the germ to others.
Staph bacteria are generally harmless unless they enter the body through a cut or other wound, and even then they often cause only minor skin problems in healthy people. But in older adults and people who are ill or have weakened immune systems, ordinary staph infections can cause serious illness called methicillin-resistant Staphylococcus aureus or MRSA.
MRSA is usually transmitted by direct skin-to-skin contact or contact with shared items or surfaces that have come into contact with someone else’s infection (e.g., towels, used bandages).
You can protect yourself from getting MRSA by:
Proper hand-washing techniques
Washing your hands is the most important tool for preventing contamination. Good hand-washing techniques include washing your hands with soap and water or using an alcohol-based hand sanitizer. Antimicrobial wipes or towelettes are just as effective as soap and water in cleaning your hands but aren’t as good as alcohol-based sanitizers.
Antibacterial soaps have become increasingly popular in recent years. However, these soaps are no more effective at killing germs than is regular soap. Using antibacterial soaps may lead to the development of bacteria that are resistant to the products’ antimicrobial agents — making it even harder to kill these germs in the future. In general, regular soap is fine. The combination of scrubbing your hands with soap — antibacterial or not — and rinsing them with water loosens and removes bacteria from your hands.
Proper hand washing with soap and water
Follow these instructions for washing with soap and water:
Proper use of an alcohol-based hand sanitizer
Alcohol-based hand sanitizers — which don’t require water — are an excellent alternative to hand washing, particularly when soap and water aren’t available. They’re actually more effective than soap and water in killing bacteria and viruses that cause disease. Commercially prepared hand sanitizers contain ingredients that help prevent skin dryness. Using these products can result in less skin dryness and irritation than hand washing.
Not all hand sanitizers are created equal, though. Some “waterless” hand sanitizers don’t contain alcohol. Use only the alcohol-based products. The CDC recommends choosing products that contain at least 60 percent alcohol.
To use an alcohol-based hand sanitizer:
If your hands are visibly dirty, however, wash with soap and water, if available, rather than a sanitizer.
