occurs in the Southeast and Southwest, between April and October, although
venomous snakebites occur at least sporadically in most states.
The poisonous snakes indigenous to the United States are members of the
Crotalidae (pit viper) or Elapidae (coral snake) families ( Table 90.21 ). The
rattlesnake, water moccasin, and copperhead are pit vipers and are responsible for
99% of venomous snakebites. The coral snake is the only member of the Elapidae
family in this country and, along with imported exotic snakes, accounts for the
remaining 1% of serious snakebites. Cobras are also members of the Elapidae
family but are not native to the United States. Snakebites have been associated
with alcohol/drug intoxication, and bites are often provoked when people try to
catch a wild snake or while caring for captive snakes.
