In 2006, emergency physician Sean Bush faced every parent's nightmare. His two-year-old son Jude was in their Southern California backyard when he spotted a juvenile southern Pacific rattlesnake coiled next to a water sprinkler. "He tried to pick it up," Bush recalls. Fortunately, Bush is one of the country's foremost experts in snake venom and had treated countless victims of rattlesnake bites—people arriving by helicopter "with total body twitching," bleeding, unable to breathe, their bodies swelling. He had antivenom ready and waiting. Jude survived. But the experience highlights a strange reality: the only effective treatment for venomous snake bites is extraordinarily expensive and surprisingly hard to find.
