National public health officials in Finland are monitoring the situation following local reports of Yersinia outbreaks.
Two outbreaks of Yersinia enterocolitica serotype O:3 have been reported to the Finnish Institute for Health and Welfare (THL) in recent weeks from the South Savo and Helsinki-Uusimaa regions.
Another suspected outbreak has been recorded in the Pirkanmaa region but patient samples have not been serotyped. People fell sick between early and mid-February.
A total of 39 cases were noted in all of Finland in February 2022, which is less than the 55 infections in February 2021.
In February 2022, five cases of Yersinia enterocolitica from South Savo were reported to the Infectious Diseases Register, which is run by THL, while from 2019 to 2021 there were no illnesses at the same time.
