Community-acquired methicillin-resistant staphylococcus aureus: an emerging problem in the athletic population

Area of Science:

• Infectious Diseases
• Sports Medicine
• Public Health

Background:

• Contact sports participants are susceptible to skin and soft tissue infections.
• Outbreaks are caused by various pathogens, including Staphylococcus aureus, herpes simplex virus, Streptococcus pyogenes, and fungi.
• Methicillin-resistant Staphylococcus aureus (MRSA), once a nosocomial pathogen, is now an emerging community threat, especially in athletes.

Purpose of the Study:

• To highlight the increasing incidence of community-acquired MRSA (CA-MRSA) outbreaks in athletic teams.
• To inform sports medicine physicians about the epidemiology and transmission of CA-MRSA.
• To emphasize the importance of understanding CA-MRSA for effective outbreak management.

Main Methods:

• Review of reported outbreaks of skin and soft tissue infections in contact sports.
• Discussion of the characteristics and transmission routes of CA-MRSA.
• Analysis of treatment challenges and morbidity associated with CA-MRSA infections.

Main Results:

• CA-MRSA is a significant cause of soft tissue infection outbreaks in athletic populations.
• MRSA spreads through person-to-person contact and can be harbored by asymptomatic carriers.
• CA-MRSA infections are resistant to traditional beta-lactam antibiotics and can lead to severe illness, requiring hospitalization and intravenous antibiotics in up to 70% of cases.

Conclusions:

• Sports medicine physicians need a comprehensive understanding of CA-MRSA epidemiology.
• Prompt identification, appropriate treatment, and control measures are essential to manage CA-MRSA outbreaks in athletes.
• Failure to address CA-MRSA can result in substantial morbidity and prolonged team absences.
