Why do most people die from bee stings than shark bites?

Perhaps you mean "more" people die from bee stings than shark bites. The most obvious reason is that human encounters with bees are everyday and constant while swimming with sharks is rather rare. The more complex reason has to do with anaphylaxis

which is most often due to allergens in foods, drugs, and insect venom. Specific causes include:

• Fish, shellfish, and mollusks
• Nuts and seeds
• Stings of bees, wasps, or hornets
• Papain

  from meat tenderizers

• Vaccines, including flu and measlesvaccines
• Penicillin
• Cephalosporins
• Streptomycin
• Gamma globulin
• Insulin
• Hormones (ACTH, thyroid-stimulating

  hormone)

• Aspirinand other NSAIDs
• Latex, from exam gloves or condoms, for example.

EMT training is extensive in this area. The onset of life threatening systemic events can be very rapid or delayed. Breathing is altered, shock can set in. One victim describes it this way: "I

have been having episodes that I think are anaphylactic

shock. It is always the same. First my hands start itching then the top of my head and it works its way down my whole body. I have rashes and welts and red patches all of which itch horribly. This last about 15 minutes. Then I start throwing up then diarrhea this stage last about 30 minutes. Then I get really hot followed by being horribly cold and that when the cramps starts. I begin to have difficulty breathing and my lips and tongue start to swell. I can stand up during any of this or I black out."
