This document analyzes EU surveillance data from 2009-2014 on shigellosis, a bacterial infection transmitted through contaminated food or water or directly from person to person through feces. The analysis found that domestically-acquired shigellosis cases increased over this period and accounted for over half of reported cases in 2014, with the proportion of cases among men doubling. Male-to-female ratios were highest among domestic cases, suggesting ongoing sexual transmission of certain Shigella strains like S. flexneri serotype 3a among men who have sex with men in Europe. The authors conclude countries should investigate domestic male cases and sexual transmission more and report such data to help monitor trends and facilitate public health interventions.
