Available data suggest a high burden of methicillin-resistant staphylococcus alums (MRSA) in Arab countries of the Middle East and North Africa (MENA). To review the MRSA rates and molecular epidemiology in this region, we used PubMed search engine to identify relative articles published from January 2005 to December 2019. Great heterogeneity in reported rates was expectedly seen. Nasal MRSA colonization ranged from 2%-16% in Gulf Cooperation Council (GCC), 1-9% in the Levant, and 0.2%-9% in North African Arab states. Infective MRSA rates ranged from 9%-38% in GCC, 28%-67% in the Levant, and 28%-57% in North African states. Studies demonstrated a wide clonal diversity in the MENA. The most common molecular types belonged to 5 clonal complexes (CC) known to spread worldwide: CCS, CC8, CC22, CC30, and CC80. The most prevalent strains had genotypes related to the European community-acquired MRSA (CA-MRSA), Brazilian/Hungarian hospital-acquired MRSA (HA-MRSA), UK-EMRSA-15 HA-MRSA, and USA300 CA-MRSA. Finally, significant antimicrobial resistance was seen in the region with variation in patterns depending on location and clonal type. For a more accurate assessment of NIRSA epidemiology and burden, the Arab countries need to implement national surveillance systems.
