Detection of vaccine-derived poliovirus type 2 from sewage samples and public health response, Poland, November to December 2024.

In October and December 2024, circulating vaccine-derived poliovirus type 2 (cVDPV2) was detected from two wastewater samples in Poland during routine environmental surveillance. The first isolate was characterised and matched previous cVDPV2 isolates detected in Spain in September, as well as in Germany, Finland, and the United Kingdom in November and December 2024. In response to the event, active surveillance for acute flaccid paralysis (AFP) has been strengthened, and the frequency of environmental sample collection has been increased.

A cross-sectional study among Polish hunters: seroprevalence of hepatitis E and the analysis of factors contributing to HEV infections.

Hepatitis E virus (HEV) is known as zoonotic agent. The main reservoirs of HEV in Europe are pigs, wild boars, and deer. Hunting activity is considered to be a risk factor for HEV infection.

Occurrence and maintenance of hantavirus infections among rodent populations in their natural habitat--results of a field study from Podkarpackie province, Poland 2010-2012.

Unlabelled: Human cases of hantavirus infection have been reported annually in Poland's Podkarpackie province, since 2007. In 2014 the number of cases reported significantly increased prompting a rise in studies focusing on the infection.

Objective: The purpose of this study was to evaluate the prevalence, maintenance and the dynamics of hantavirus infection among rodent species, including the bank vole (Myodes glareolus) and yellow-necked mouse (Apodemus flavicollis) which act as reservoirs of hantavirus in the environment.

Hepatitis A in Poland in 2013.

Objective: The aim of the study is to assess the epidemiological situation of hepatitis A in Poland in 2013 compared to previous years.

Material And Methods: The evaluation was carried out on the basis of the results of the analysis of data from the annual bulletin "Infectious diseases and poisonings in Poland in 2013" and "Vaccinations in Poland in 2013", the information from individual diseases forms and epidemiological investigations forms for hepatitis A outbreaks, sent by sanitary-epidemiological stations to the Department of Epidemiology of NIZP-PZH.

Results: In 2013, 48 cases of hepatitis A were registered in Poland.

Large and prolonged food-borne multistate hepatitis A outbreak in Europe associated with consumption of frozen berries, 2013 to 2014.

In May 2013, Italy declared a national outbreak of hepatitis A, which also affected several foreign tourists who had recently visited the country. Molecular investigations identified some cases as infected with an identical strain of hepatitis A virus subgenotype IA. After additional European Union/European Economic Area (EU/EEA) countries reported locally acquired and travel-related cases associated with the same outbreak, an international outbreak investigation team was convened, a European outbreak case definition was issued and harmonisation of the national epidemiological and microbiological investigations was encouraged.
