Azithromycin-Nonsusceptible<i>Shigella flexneri</i>3a in Men Who Have Sex with Men, Taiwan, 2015–2016

Abstract

We report an outbreak of azithromycin-nonsusceptible Shigella flexneri 3a infection in Taiwan associated with men who have sex with men. The bacterial strains belonged to the sublineage A of a recently reported outbreak lineage associated with men who have sex with men, characterized by reduced azithromycin susceptibility and circulation in shigellosis low-risk regions.
