Richard H. Sinert, DO

Disclosures January 10, 2017

Most snakebites are innocuous and are delivered by nonvenomous species. North America is home to 25 species of venomous snakes. Worldwide, only about 15% of the more than 3000 species of snakes are considered dangerous to humans. Although death is rare, local complications from envenomation may occur.

蛇咬伤多数为无毒蛇咬伤因而危害不大。北美共有25种毒蛇。全世界超过3000种蛇中仅有大约15%对人类有危害。尽管很少引起死亡,但毒蛇咬伤可引起局部并发症。

Copperhead bites are generally limited to localized tissue destruction. Rattlesnakes can cause both localized symptoms and systemic toxicity. Cobra bites frequently do not result in envenomation and are so-called dry bites.
