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.
Rapid risk/outbreaks assessment aim at supporting the countries and the European Commission in their preparedness and response to a public health threat. They provide a timely summary and risk assessment of a public health threat for EU/EEA countries related to a specific event. They also include potential options for response. As outbreaks or public health events develop, ECDC may issue updated risk assessments.
On 24 March 2017, the German authorities reported the contamination of a ‘do-it-yourself’ bacterial gene engineering CRISPR kit produced in the US. This publication assesses the risk related to the use of ‘do-it-yourself’ CRISPR-associated gene engineering kit contaminated with pathogenic bacteria.
On 31 August 2016 the autonomous Community of Madrid, Spain, reported two cases of infection with Crimean–Congo haemorrhagic fever (CCHF) virus. This document assesses the risk associated with the occurrence of two cases of Crimean–Congo haemorrhagic fever in Spain.
This document assesses the risk to human health posed by a multi-country foodborne outbreak of Shiga toxin-producing Escherichia coli (STEC) infections associated with haemolytic uraemic syndrome taking place in the European Union (EU).
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.
This document is an update of the EFSA/ECDC joint rapid risk assessment of 29 June and aims to add new information to this and earlier initial rapid risk assessments (27 May and 14 June 2011).
