Austria has also been affected, with six people falling ill. The Ministry of Health has tasked the AGES with investigating this foodborne outbreak.
The identification of a close genetic cluster spanning several countries, combined with the temporal distribution of the cases, points to a probable common source of the outbreak. Children and young adults are disproportionately represented among those affected, which could indicate specific dietary habits. However, no suspected source of infection has been identified so far.
The investigation into these foodborne disease outbreaks is being conducted in close cooperation between AGES, the Ministry of Health and the relevant provincial authorities, as well as in collaboration with the European authorities.
