An increased reporting of shigellosis cases, mainly caused by Shigella sonnei, among travellers returning from Cabo Verde has been ongoing in the European Union/European Economic Area (EU/EEA), the United Kingdom (UK), and the United States (US) since September 2022. This outbreak evolved rapidly during November and December 2022.
This document assesses the risk of further spread of S. sonnei amongst MSM and in the broader population in EU/EEA countries, resulting from the current increase in extensively-drug resistant S. sonnei infections.
