Evolving epidemiology of Q fever in Wide Bay.

Q fever is a notifiable disease in Australia due to its public health significance. Recent data in the Wide Bay region (Queensland, Australia) suggests a rising number and changing geographical distribution of Q fever cases. This study aims to evaluate these changes through analysis of data from Queensland Health's Notifiable Conditions System (NoCS) over a ten-year period. A comparison was made between the recent five-year period (2018-2022) and the preceding five-year period (2013-2017) with reference to incidence rates, location of cases and likely exposures. Incidence rates of Q fever showed an upward trend over time, particularly in urban areas. This highlights the need for increased clinical suspicion, improved awareness among the community and healthcare providers, and potentially broadening of vaccination recommendations in the future.
