Methicillin Resistant Staphylococcus aureus and public fomites: a review

Area of Science:

• Microbiology
• Infectious Diseases
• Public Health

Background:

• Staphylococcus genus, including Staphylococcus aureus, is a common bacterium found on skin and mucous membranes.
• S. aureus possesses virulence factors enabling immune evasion, and antimicrobial misuse has led to antibiotic resistance.
• Methicillin-Resistant Staphylococcus aureus (MRSA) emerged due to resistance to methicillin, becoming a significant nosocomial pathogen (HA-MRSA) and later a community-associated threat (CA-MRSA).

Purpose of the Study:

• To review the worldwide prevalence of MRSA on fomites.
• To analyze MRSA presence in both hospital and community settings.
• To highlight the significance of fomites as reservoirs for MRSA transmission.

Main Methods:

• Literature review of studies reporting MRSA isolation from fomites.
• Analysis of data on MRSA prevalence in hospital environments.
• Analysis of data on MRSA prevalence in community settings.

Main Results:

• MRSA has been detected on fomites within hospital settings, including patient-contact items and staff belongings.
• MRSA has also been isolated from fomites in community environments over the past 20-25 years.
• Fomites serve as potential reservoirs for MRSA transmission in both healthcare and community contexts.

Conclusions:

• MRSA is prevalent on fomites globally in both hospital and community settings.
• Understanding fomite contamination is crucial for controlling MRSA spread.
• Further research is needed to elucidate the role of fomites in MRSA epidemiology.
