What should you do if you are attacked by a swarm of Africanized bees? You may be able to outrun them; they are slower than European bees. Don’t run toward other people, as you will subject them to attack as well. And don’t try to escape the bees by plunging into a river or lake; they will swarm overhead and wait for you to surface. If you are allergic to bee stings and you are stung, get to a hospital quickly. Even if you are not allergic, repeated stings can be dangerous.
