MRSA Infection

MRSA infection is caused by a bacterium called Methicillin-resistant Staphylococcus aureus. Methicillin-resistant Staphylococcus aureus (MRSA) is a type of bacteria that has become resistant to many of the antibiotics used to treat  staph infections.

Depending on the area infected, the symptoms may vary. Most MRSA infections are not severe, but some of them can endanger your life. 

Introduction to MRSA infection

MRSA infection is caused by a kind of staph bacteria that has become resistant to most of the antibiotics we use to treat staph infections. These bacteria are naturally present in the nose and on the skin.

Usually, they do not harm you, but infection generally happens when there is a cut or break in the skin and in healthy people thet usually only cause minor  skin problems . However , it is very contagious and can spread via direct contact with someone infected. A person can also contract it if they contact an object or surface that a person with MRSA has touched. 

Antibiotic Resistance

MRSA is the result of years of often needless use of antibiotics. For many years, antibiotics have been prescribed for flu, colds and other viral infections that don’t respond to these drugs.

If MRSA infection happens to people in medical facilities like nursing homes and hospitals, it is called HA-MRSA, i.e., healthcare-associated MRSA. If MRSA infections get transmitted via personal contact with an infected person in the general community , it is called Community-Associated MRSA(CA-MRSA).

What are the Symptoms of MRSA infection?

MRSA infection starts as swollen, red, painful bumps that may appear to be pimples or spider bites. Your affected area might have the following : 

  1. Rash
  2. Feel Warm to touch
  3. Swollen and painful bump
  4. Pus or drainage of other fluids  in the infected area
  5. Fever 

The bumps may worsen into deep, painful boils (abscesses) which needs surgical draining. Sometimes the bacteria may also burrow deep into the body, leading to potentially life-threatening infections in bones, surgical wounds, joints, heart valves the bloodstream, and lungs.

Risk factors for Hospital acquired MRSA

  • Being hospitalized 
  • Having an invasive medical device 
  • Residing in a long-term care facility 

Risk factors for Community Acquired MRSA

  1. Participating in contact sports: MRSA may spread easily through cuts and scrapes and skin-to-skin contact.
  2. Living in crowded or unsanitary conditions 
  3. Men having sex with men
  4. Having HIV infection 
  5. Using illicit injected drugs

When to See a Doctor

Watch out for any minor skin problems like cuts, pimples, scrapes, insect bites, etc., particularly in children. If the wound appears to be infected or you get a fever along with it, please consult your doctor.
