Many victims, the report said, spend their savings, sell land or pull their kids out of school to help pay for snakebite treatment. Incidence tends to grow mechanically as a function of demography although there is a partial offset related to a decrease due to anthropization of the environment which reduces snake populations and/or snake-man contacts. 5.

From these, the ICP technicians have built an impressive stock of extracted venoms, supplemented with occasional imports of exotic venoms. However, although spiders are more widespread than snakes, snakes kill far more people each year than spiders. The deadliest animals in the world based on the number of human deaths per year is not a creature that humans usually find scary, such as a lion or snake.
