[Adder bites in France]

Snake bites are a major public health problem in the tropics but they have a low incidence in Europe and are responsible for few deaths each year. The incidence is higher in children than in adults but no difference in severity seems to be observed between children and adults. In France, snake envenomations are due mainly to Vipera aspis and Vipera berus. The clinical presentation is usually limited to a local syndrome with pain and local inflammatory edema, but systemic signs occur in 17% of cases. Clinical grading published by the Institut Pasteur in Paris helps to assess the severity of envenomation and to decide the use of antivenom. Every bitten patient must be transferred in a hospital for medical assessment. Specific treatment is based on antivenom immunotherapy. However, other medical and surgical treatments have limited value.
