[Hiking and useful advices to patients (part 1)]

The attraction of walking as a pastime has grown enormously in Switzerland over the past few years. Synonym of health and well-being, this activity carries some risks which more and more patients are questioning; answering these questions is not always obvious, so we wanted to tackle the subject. Risks linked to certain animals will be covered. One of these risks is insect stings, particularly wasps and bees. This is a major problem which affects the whole population and more seriously those who are allergic, accounting for around 5% of the population. Another problem: snake bites. In Switzerland, there are about 20-25 bites each year. Poisoning from these can be divided into two categories: local or systemic. The effects are multiple and diverse, ranging from renal failure to discrasia to hypovolemic shock. Pre-hospitalisation measures are of paramount importance in the treatment.
