Swiss Study on Spider Bites (SSSB)

October 1, 2013 updated by: University of Zurich
About spider bites in Middle Europe, there are published only a dozen cases. The investigators suspect that they may be much more frequent than reflected by the literature analysis (but much less dangerous than thought by people). From June 1st 2011 to November 30st 2012 the investigators collect clinical data on patients treated for spider bites in Switzerland.
