Methicillin-resistant Staphylococcus aureus (MRSA) skin infections have become an escalating public health concern. This antibiotic-resistant “superbug” can cause symptoms ranging from mild to life-threatening. By learning the signs, risk factors, and evidence-based prevention/treatment strategies, you can protect yourself and effectively manage staph skin infections if they occur.

Recognizing an MRSA Skin Infection

Staphylococcus aureus (staph) bacteria commonly colonize human skin and mucous membranes without causing issues. However, they can lead to infection if they breach the skin, especially for those with weakened immune systems. MRSA refers to staph strains that have become resistant to common antibiotics like penicillin and methicillin.

MRSA lives on the skin and can enter through any cracks or damage leading to:

  • Swelling, redness, pus-filled bumps
  • Staph boils or pus-filled abscesses
  • Painful inflammation and skin infection
  • Impetigo blisters/crusting

Symptoms typically begin 24-48 hours after skin penetration. MRSA spreads easily through contact and can appear red, swollen, and resemble spider bites. Seek medical care promptly if you suspect an infection.


Who Gets MRSA Skin Infections

You have an increased risk of developing an MRSA skin infection if:

  • You have an open cut, scrape, or surgical wound
  • You share close living or working spaces
  • You participate in contact sports
  • You have a weakened immune system
  • You work in a health care facility

Jails, schools, military barracks, and athletics teams have seen MRSA outbreaks. Using shared equipment in gyms also poses risks.

Dangers and Complications

Most MRSA skin infections respond readily to drainage and antibiotics. However, more serious complications can develop without proper treatment, requiring hospitalization.

Potential complications include:

  • Widespread soft tissue infections
  • Bacterial infection spreading to blood (sepsis)
  • Recurrent infections
  • Life-threatening pneumonia
  • Permanent tissue damage from flesh-eating disease

Seeking timely medical care is extremely important with MRSA.

Preventing MRSA Skin Infections

You can reduce MRSA risks considerably through:

Hand Hygiene

Washing hands thoroughly with soap and water after touching infected skin or contaminated items remains vital to controlling spread. Alcohol sanitizers do not kill MRSA.

Protect Skin

Keep skin healthy and intact. Treat any scrapes/cuts promptly, keep them covered, and avoid contact sports or shared equipment use until healed. Shower right after athletic exposures.


If you experience recurrent infections, temporary nasal antibiotics combined with skin disinfectants helps eliminate MRSA from your body. This prevents further spread and reinfection.

Clean Surfaces

Use EPA-approved disinfectants suitable for MRSA control in gyms, locker rooms, and other high traffic areas. Bleach solutions also work.

Follow all medical facility infection control protocols if visiting hospitals. Caregivers should wear gloves and gowns over clothing when bandaging wounds.


Treating an MRSA Skin Infection

See a doctor at the first signs of infection for proper care. Typical treatment involves:

Wound Drainage

MRSA abscesses require opening and draining pus. This provides culture samples and brings immediate relief.

Oral or IV Antibiotics

Cultures determine which antibiotics will prove effective to clear your specific strain. Typical options include TMP/SMX, doxycycline, clindamycin or vancomycin for serious infections.

Take antibiotics consistently for the full course as prescribed to prevent recurrence. Isolate yourself from skin contact with others for 24 hours after starting medications.

Surgical Debridement

Some tissue damage from MRSA may require removal of dead skin and tissue through debridement surgery. This reduces infection load and helps healing.

Follow all wound care instructions closely to support healing and prevent worsening infection and complications. Call your doctor if symptoms do not start improving within 48-72 hours to reassess.

Can MRSA Be Cured?

Currently no cure for staph infections exists since bacteria naturally live on us. However, antibiotics can fully resolve individual MRSA skin infections. Preventing new colonization or infections centers around ongoing precautions and safely eliminating MRSA bacteria from your body if it takes hold.

With appropriate treatment guided by cultures, MRSA skin infections typically heal within 7-10 days. More serious infections may require hospitalization. After healing, continue protecting skin integrity, practicing good hygiene and wound care, and avoiding potential contaminations.

Common Questions about MRSA Skin Infections

How do you know you have MRSA on your skin?

Look for signs like red, swollen, warm and painful skin, pus-filled bumps, boils or blisters, especially if they enlarge rapidly or develop pus. See a doctor promptly for testing if an antibiotic-resistant staph infection is suspected for proper treatment.

Can I get rid of MRSA skin infection forever?

No guarantees exist for permanent MRSA eradication. However, temporarily eliminating it from your body and home through decolonization therapy and disinfecting can keep it away long-term. Continuing prevention methods also reduces recurrence risks considerably.

Is staph infection contagious through touch?

Absolutely. Direct skin-to-skin contact easily spreads staph bacteria. Maintain good handwashing, avoid touching active infections, and isolate contaminated wounds by fully covering them to control contagion.

How long is a staph skin infection contagious?

Infected individuals can transmit staph via contact throughout active infection and recovery. However, the highest risks come before starting treatment since antibiotics help reduce contagiousness. Staying isolated for the first 24 hours after beginning medications remains wise.

Can I treat a staph skin infection at home?

Mild early infections without swelling or pus may respond to warm compresses for comfort and topical antibiotic creams. However, any infection producing pus requires medical drainage. Rapidly worsening or extensive cellulitis also warrants physician assessment for oral antibiotics to resolve infection.

Key Takeaways for Handling MRSA Skin Infections

  • MRSA skin infections stem from antibiotic-resistant staph bacteria penetrating the skin, especially in immunocompromised hosts.
  • Prevention centers around protecting skin integrity, practicing good hygiene and wound care, and isolating infections.
  • Seek medical care promptly for appropriate wound drainage, culturing, and tailored antibiotic regimens based on strain testing.
  • Halting transmission to others hinges on keeping infected wounds covered, maintaining handwashing, and completing prescribed decolonization regimens.
  • Stay vigilant with prevention methods even after resolving infections to help avoid recurrence long-term.

With proper treatment guided by culture results, MRSA skin infections typically resolve within 1-2 weeks. However, severe or recurrent cases may require hospitalization to prevent serious complications from these highly contagious antibiotic-resistant infections.
