Invasion of the 'killer' bees. Separating fact from fiction.

Even a single honeybee sting can lead to anaphylaxis in a susceptible person, but severe reactions can result from multiple stings, particularly if stings are from the fast-spreading Africanized honeybees, sometimes called "killer" bees. Signs and symptoms of multiple stings may include urticaria, nausea, vomiting, diarrhea, hypotension, confusion, seizures, and renal failure. Treatment is entirely supportive and requires special attention to airway patency, blood pressure, and renal function. Patients with more than 50 stings are at a higher risk of toxicity. Stingers should be removed by scraping gently to prevent further venom injection. Smoke or aerosolized deet (diethyl-toluamide) may thwart attacking bees, but avoidance is the best line of defense.
