Weight lifters and competitive sports teams, including basketball, fencing, football, rugby, soccer, volleyball and wrestling have an increased risk of MRSA infection.

MRSA Skin and Soft Tissue Infection

MRSA is being reported with regular frequency of skin and soft tissue infections among sports participants. Skin and soft tissue infections occur with increasing frequency in teams involved in close contact activities where abrasions and wounds are expected (e.g. wrestling, football, volleyball, rugby, basketball, soccer, fencing).

Traditionally, Staphylococcus aureus and Streptococcus pyogenes (Group A streptococcus) are the two most common bacteria that cause skin and soft tissue infections. In recent years, methicillin resistant Staphylococcus aureus (MRSA) infections have occurred with increasing numbers among schools, athletic teams and sports teams.

Factors associated with MRSA transmission include:

• Skin-to-skin contact.
• Crowded shared living space conditions.
• Poor hygiene.
• Care of infected sites.
• Cleansing and handling of contaminated items and surfaces.

Possible risk factors for MRSA infection among sports participants:

• Physical contact*
• Skin trauma (e.g. turf burns, shaving, chafing, abrasions, wounds)
• Sharing of equipment
• Sharing of unwashed clothing and bath towels
• Sharing soaps, balms and lubricants
• Shaving of body hair**
• Uncovered wounds

*In fact, MRSA infection was found in a few studies to be associated with football player position: cornerbacks and wide receivers who are often involved in scrimmage play and drills showed significant risk of having a MRSA infection over other team members.

**In a number of cases, players with MRSA infection had shaved the area now infected.

What to Watch For?

MRSA should be suspected in outbreaks of boils and other soft tissue infections among sports team members and their close contacts that do not respond to standard antibiotic therapy.

Health-care providers must consider the possibility of MRSA soft tissue infection among sports participants so that appropriate antibiotics can be prescribed.

Implementation of Preventive Measures

Players, coaches, parents, and school and team administrators must develop and implement measures to prevent MRSA transmission.

MRSA transmission control measures include:

• Increased hand hygiene.
• Showering with soap after activities.
• Covering wounds (e.g. cuts, abrasions).
• Laundering of personal items after each use (e.g. towels, supporters, etc.).
• Disinfection of shared athletic equipments regularly (e.g. pads, helmets, fencing sensor wires, etc.).
• Consult with physician for wounds that do not heal.

Nasal carriage (colonization) with MRSA is increased with certain habits as well. Risk factors for nasal carriage included:

• having a locker near a teammate with a MRSA infection.
• sharing unwashed towels.
• living on campus.

Measures to Reduce MRSA Infection in the School and College Environment:

• Promotion of showers after practice, play and workouts
• Intermittent hexachlorophene (Phisohex) soap showers
• Hygiene education
• Prevention of turf burns
• Education on risks of cosmetic body shaving
• Appropriate whirlpool disinfection methods
• Frequent disinfection of treatment tables, taping tables and athletic equipment
• Promotion of trainer handwashing after each treatment
• Use of disposable paper towels on the field
• Ensure availability of alcohol-based hand sanitizers
• Discard used towels immediately
• Adequate laundry facilities: hot water washing and heat dried
• Prompt drainage and culture of abscesses
• Prompt recognition to ensure appropriate antibiotic therapy
• Decolonization in outbreak settings***

***Decolonization of MRSA is a controversial subject: some believe strongly in its merits and others believe it provides a false sense of confidence and encourages further antibiotic resistance due to exposure to decolonization antimicrobials.

Those who support decolonization, at least in the outbreak setting such as on a football team where multiple cases of MRSA infection occur, also support the belief that in outbreak settings there are increased numbers of participants carrying MRSA in their nasal passages. If you treat nasal carriage with nasal crops such as mupirocin, MRSA carriage can be reduced leading to a reduction in MRSA infections.

Those who do oppose decolonization are likely more ready to mention the likelihood that MRSA carriers probably also carry MRSA in their gastrointestinal tract which would suggest one reason why MRSA colonization is generally determined by swabbing the nasal passages and groin area. Although a measure such as mupirocin may suggest that MRSA carriage has been reduced, it is much more likely that MRSA will represent shortly through fecal-skin/fecal-hand contamination and inoculation of the nasal passages.
