Overview
Introduction: Q fever is a zoonosis with a worldwide occurrence. Coxiella burnetii infection is most commonly transmitted by inhalation of air containing contaminated dust in cow, sheep and goat farming areas. The other modes of transmission are alimentary route (ingestion) and through sucking ticks. We set ourselves the goal of presenting a descriptive analysis of cases of Q fever in the Czech Republic (CZ) and former Czechoslovakia and draw attention to this often-overlooked issue.
Methods: Summary of available information about Q fever was processed, and a narrative search of published cases of Q fever in the CZ and former Czechoslovakia, in Czech, Slovak and English, without time restrictions was performed. Furthermore, a descriptive analysis of Q fever cases reported to the Czech infectious diseases reporting system in 1982–2021 was done. After analysis, the available information system data were supplemented with data from a search of published scientific literature and weekly reports on the current epidemiological situation of the public health protection authorities of the CZ.
Results: The disease has been reported in former Czechoslovakia and then in CZ since 1952. In 1952–1954, six outbreaks were reported with a total of 150 cases, mostly in connection with work with cattle. In 1980, a large-scale outbreak of Q fever affected 526 employees of the cotton production plant at Staré Město near Uherské Hradiště. Otherwise, units to dozens of cases were reported. From 1993 to 2021, 27 cases of the disease were detected in the CZ, of which 22 (81.5%) occurred in men. The age range was 0–60 years (mean 31, median 30 years). Seasonality by reporting month was highest in January and September.
Conclusion: There has been a decline in human cases of Q fever in the European Union (EU) in recent years, and only few cases of the disease occur in the CZ. Still, due to potential severity of the disease, the current climate change with the consequent increase in the spread of ticks as vectors of Coxiella, and animal movements associated with the global market, it is important to consider Q fever in the differential diagnosis. As part of the prevention, it is necessary to ensure compliance with basic hygiene rules, especially in at-risk occupations, and to consume only pasteurized dairy products. Vaccination of humans is not available in EU countries, although vaccination of livestock is possible.
