Fig. 2

Temporal occurrence of sarcoptic mange cases in Switzerland according to the surveillance method (1958–2018). a Percentage of sarcoptic mange and number of red foxes (Vulpes vulpes) with and without sarcoptic mange (confirmed through mite identification) submitted in the framework of the general health surveillance programme for wildlife (source: FIWI). b Percentage of foxes with sarcoptic mange (1968–1992; data not available for 1974 and 1977) and number of foxes analysed and tested for rabies (1967–1996) during the rabies eradication campaign (source: SRC). c Percentage and number of questionnaires reporting mange-like lesions (not confirmed by mite identification) in the framework of a yearly questionnaire survey (2001–2017; source: FIWI). d Number and prevalence of camera-trap pictures showing foxes with mange-like lesions. Pictures were bycatch material collected during the Eurasian lynx camera-trapping monitoring (2005–2018; source: KORA). e Number of foxes culled or found dead at national level (source: national hunting statistics). The left y-axes of diagrams a-d represents the respective percentages or prevalences. The left y-axis of diagram e represents the number of foxes shot. The right y-axes represent the number of units analysed and differ among data sources (a necropsies performed, b foxes examined for rabies, c questionnaires returned, d camera-trap pictures, e foxes found dead). Abbreviations: MLL, mange-like lesions; SM, sarcoptic mange
