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.
The occurrence of shigellosis among refugees is not unexpected because shigellosis is endemic in the countries they originate from, as well as in some of the countries they travel through.
An increase in cryptosporidiosis notifications has been observed in the United Kingdom, the Netherlands and Germany since August 2012 that is likely to be real, and not due to surveillance or notification artefacts.
