Notes:
a
Prevalence within subgroups with >1 study included was presented as range, otherwise a single prevalence was presented.
b
Two studies provided one combined data (Appendix XII, Appendix XXV).
Abbreviations: BSI, blood stream infection; CA-MRSA, community-associated methicillin-resistant Staphylococcus aureus; DM, diabetes mellitus; ENT, ear, nose, and throat; HIV, human immunodeficiency virus; SSTIs, skin and soft tissue infections.
