Campylobacteriosis in Poland in 2018-2019.

INTRODUCTION

Campylobacteriosis is a zoonotic disease caused by bacteria of the genus Campylobacter. This disease usually presents with symptoms of acute gastroenteritis. The majority of Campylobacter infections are usually acquired through consumption of contaminated water or food, less frequently through direct contact with an infected animal or person. In Poland, campylobacteriosis is notifiable disease, according to the EU deffinition implemented in the polish surveillance system.

AIM OF THE STUDY

The aim of this study is to assess epidemiological situation of campylobacteriosis in Poland in years 2018-2019 and compare it to previous years.

MATERIALS AND METHODS

The study was based on data from the bulletins 'Infectious Diseases and Poisonings in Poland' for 2018-2019 issued by the National Institute of Public Health NIH - National Research Institute and data submitted to the System for Registration of Epidemiological Interwiews (SRWE) by District Sanitary and Epidemiological Stations.

RESULTS

In Poland 726 cases of Campylobacterosis were reported in 2018 and 715 in 2019. There was a decrease in the number of reported cases in comparision to 2017 by 17% and 19% in 2018 and 2019 respectively. Cases of campylobacteriosis were reported in all voivodeships, with the highest incidence in both described years in Lubuskie voivodeship. Campylobacteriosis was diagnosed in patients in all age groups but the majority of patients were children under the age of 4. The most frequently identified species was Campylobacter jejuni.

SUMMARY AND CONCLUSIONS

Data on the number of campylobacteriosis infections in Poland for 2018 and 2019, demonstrate a stabilized epidemiological situation regarding this disease entity in the country. The high hospitalization rate of patients diagnosed with campylobacteriosis, demonstrates the need to implement microbiological diagnostics in cases of suspected disease. Data show a much lower incidence rate of campylobacteriosis in Poland, compared to other EU countries, which suggests potential underestimation of the actual number of infected case.
