  Purpose

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.

Primary Outcome Measures:
  • Clinical follow up of bite lesions. [ Time Frame: 14 days (or more if necessary) ] [ Designated as safety issue: No ]
    Clinical evolutions of actual spider bite lesions in humans are observed.


Secondary Outcome Measures:
  • Time spread of spider bites [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    Frequencies of spider bites over the study period of 18 months are observed.

  • Causative animals [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    To determine spider species causing bites in Switzerland by sending spider specimens to an expert arachnologist.


Biospecimen Retention:   None Retained

Species of biting spider will be assessed if specimen is sent to us.
