Outbreak of tularaemia connected to a contaminated well in the Västra Götaland region in Sweden.
Tularaemia, is a zoonotic disease caused by the bacterium Francisella tularensis. This disease has been reported in Sweden since 1931 and its wide distribution in the country poses a challenge for understanding the transmission, ecology and epidemiology of the disease. In Sweden, the disease is usually transmitted by mosquitoes, but in this study we could show that consumption of well water was epidemiologically linked to the outbreak, by isolating F. tularensis from the water. In this article, we describe an outbreak of tularaemia in the region of Västra Götaland in the southwest of Sweden in spring of 2013.
