Wong JWH, et al. - The researchers conducted this systematic review and meta-analysis to estimate the population-level prevalence and subgroup-specific prevalence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) carriage in the Asia-Pacific region. In addition, they planned to synthesize information about factors related to CA-MRSA carriage. Using the MEDLINE, EMBASE, and PubMed databases to search for articles published from January 1, 2000 to May 19, 2017, that reported CA-MRSA carriage (defined as either colonization or infection) in Asia-Pacific region (2000-2016), they identified 152 relevant studies. They observed a large degree of diversity among studies in most study groups. From community-level studies, countries with the highest prevalence were India, followed by Vietnam, and Taiwan. The authors suggested that their estimates on the prevalence of CA-MRSA can serve as the baseline for future national and international surveillance, and the ranges of prevalence and characteristics associated with CA-MRSA carriage can help to inform health authorities to develop infection-control policies for high-risk subgroups. They recommended future studies to explore the heterogeneities in CA-MRSA carriage prevalence among subgroups and countries to clarify the predominant transmission mechanisms in Asia-Pacific and other regions.
