Incidence of the natural disease in humans is dependent on the level of exposure to affected animals. For any country, national incidence data for non-industrial cases reflect the livestock situation. Human case rates for<unk>  are highest in Africa and Central and Southern Asia. While, statistically, in Northern Europe and countries with similar epidemiological situations, there is one human cutaneous case per every 10 livestock carcasses butchered, there can be some 10 human cutaneous and enteric cases per single carcass butchered in Africa, India, and the Southern Russian Federation.
