Background: The aim of our study was to analyse the influence of air temperature and implemented veterinarymeasures on salmonellosis incidence in the Czech Republic (CZ).
Methods: We conducted a descriptive analysis of salmonellosis as reported to the Czech national surveillancesystem during 1998–2017 and evaluated the influence of applied veterinary measures (started in January 2008) onsalmonellosis incidence by comparing two 9-year periods (1998–2006, 2009–2017). Using a generalized additivemodel, we analysed association between monthly mean air temperature and log-transformed salmonellosisincidence over the entire twenty-year period.
Results: A total of 410,533 salmonellosis cases were reported during the study period in the CZ. Annual meanincidences of salmonellosis were 313.0/100,000 inhabitants before and 99.0/100,000 inhabitants afterimplementation of the veterinary measures. The time course of incidence was non-linear, with a sharp declineduring 2006–2010. Significant association was found between disease incidence and air temperature. On average,the data indicated that within a common temperature range every 1 °C rise in air temperature contributed to asignificant 6.2% increase in salmonellosis cases.
Conclusions: Significant non-linear effects of annual trend, within-year seasonality, and air temperature on theincidence of salmonellosis during 1998–2017 were found. Our study also demonstrates significant direct effect ofpreventive veterinary measures taken in poultry in reducing incidence of human salmonellosis in the CZ. Theannual mean number of salmonellosis cases in the period after introducing the veterinary measures was only 32.5%of what it had been in the previous period.
