If you fear snakes, it is probably because you are unfamiliar with them or you have wrong information about them. There is no need for you to fear snakes if you know--

For a man wearing shoes and trousers and living in a camp, the danger of being bitten by a poisonous snake is small compared to the hazards of malaria, cholera, dysentery, or other diseases.

Nearly all snakes avoid man if possible. Reportedly, however, a few--the king cobra of Southeast Asia, the bushmaster and tropical rattlesnake of South America, and the mamba of Africa--sometimes aggressively attack man, but even these snakes do so only occasionally. Most snakes get out of the way and are seldom seen. However in a wilderness survival situation you need to be prepared for anything, and while snake attacks are rare they can be deadly.
