Query fever: an opportunity to understand the disease better.

This week’s issue of Eurosurveillance presents two articles on Q fever. A surveillance report about a Q fever outbreak in Cheltenham, United Kingdom (UK), describes the traditional pattern of Q fever epidemiology involving clusters of cases reported around farms with infected animals (sheep, goats) [1]. The second article provides an update on a long-lasting and ongoing Q fever outbreak with a considerable increase in cases observed over the past three years, indicating an entrenchment of Q fever in certain areas of the country [2].
