Snakebite

A wound caused when a snake bites a person or animal. Some bites inject venom, while others are dry bites with no venom delivery.

Snake venom: A mixture of biologically active substances produced by venomous snakes and delivered through specialized fangs. Its composition determines which symptoms a venomous bite can produce.
Snakebite first aid: Immediate care intended to limit harm after a snakebite before definitive medical treatment. Appropriate first aid can reduce complications while transport to care is arranged.
Bothrops asper: A venomous pit viper found in Central America and parts of northwestern South America. Its bites are a major cause of severe local injury in parts of its range.
Snakebite envenoming: Illness caused by venom injected during a snakebite. It captures the systemic medical consequences of venomous bites.
Snake bite mark identification: The interpretation of punctures and other skin marks to assess a suspected snakebite. Puncture patterns alone cannot reliably identify the snake or prove venom injection.
Snake fangs: Modified teeth that some snakes use to puncture prey or deliver venom. Fang structure affects how venom enters tissue during a bite.
Antivenom: A medicine containing antibodies or antibody fragments that neutralize animal venoms. It is the specific treatment for clinically significant snake envenomation.
Russell's viper: A venomous viper native to parts of South Asia and Southeast Asia. Its bites can cause dangerous clotting disorders and kidney injury.
Snakebite-associated acute kidney injury: A sudden decline in kidney function caused by complications of snake envenoming. Some venoms and resulting blood disorders can damage the kidneys.
Spider bite: A wound caused by a spider's mouthparts, sometimes accompanied by venom effects. Skin lesions attributed to snakebite can have other causes, including spider bites.
