ECDC - Risk assessments

Between January and May 2026, 109 confirmed cases of Salmonella Bovismorbificans ST377 were reported from 10 European Union/European Economic Area (EU/EEA) countries (Austria, Belgium, Czechia, Denmark, Finland, Germany, Ireland, Luxembourg, Spain and the Netherlands) and the United Kingdom.

Several clusters of genetically and epidemiologically linked cases predominantly affecting gay, bisexual and other men who have sex with men have been detected in four EU countries during the past six months. Cases have also been reported in Norway among individuals practicing martial arts, in 2025 and 2026.

The overall risk of Bundibugyo virus transmission through substances of human origin (SoHO) in the European Union/European Economic Area (EU/EEA) is currently assessed as very low.

The ongoing outbreak of Ebola disease caused by Bundibugyo virus in the Democratic Republic of the Congo (DRC) and Uganda reported in May 2026 has prompted ECDC to review its operational guidance relevant to air travel. In this context, updated guidance is needed to support preparedness and public health action if a case is identified during or after a flight.

On 15 May 2026, Africa CDC reported an outbreak of Ebola disease in Ituri Province, DRC. Laboratory analysis at Institut National de Recherche Biomedicale of DRC identified Bundibugyo virus (BDBV). BDBV disease is a rare disease but can cause outbreaks with high case fatality rates. Considering the available information, complicated context and the uncertainties on the epidemiological information WHO declared a Public Health Emergency of International Concern on 17 May 2026. Africa CDC declared a Public Health Emergency of Continental Security on 18 May 2026.

This document aims to provide advice on infection prevention and control (IPC) measures for healthcare facilities providing care to patients with suspected or confirmed ANDV disease.

This document provides advice for public health professionals in the EU/EEA managing individuals potentially exposed to Andes virus infection.
