The study describes the risk of dying from an adder bite as a human as comparably low. Reportedly 70% of the bites result in no, or not significant envenomation. The general mortality rate is described as 1.22 deaths per 1000 people bitten, which is comparatively low. However, reported hospitalisation of humans after a bite was reported in a range from 1 to 29 days. And the author reports cases of cattle that had to be put down as a consequence of a received adder bite. In short: The chance to die from an adder bite is low, but severe evenomations can kill humans and bring even big animals like cattle down.
