Definition:

Each year in the United States, there are over 8,000 poisonous snakebites -- mostly in the summer season.

Poisonous snake bites are medical emergencies, and they can be deadly if not treated quickly.

Alternative Names:
Bites - snakes
Considerations:

Children are at higher risk for death or serious complications due to snake bites because of their smaller body size. However, the right antivenom can save a person's life. Getting the person to an emergency room as quickly as possible is very important. If properly treated, many snakebites will not have serious effects.

Causes:

Poisonous snake bites include bites by any of the following:

  • Rattlesnake
  • Copperhead
  • Cottonmouth (water moccasin)
  • Coral snake
  • Cobras
  • Various snakes found at zoos
All snakes will bite when threatened or surprised, but most will usually avoid an encounter if possible and only bite as a last resort. Snakes found in and near water are frequently mistaken as being poisonous. Most species of snake are harmless and many bites will not be life-threatening, but unless you are absolutely sure that you know the species, treat it seriously.
Symptoms:
