उत्तर
An anaphylactic shock reaction similar to injection of a foreign protein can be triggered when an antigen enters the bloodstream from a bee sting or wasp sting. In sensitive individuals, the venom enters the bloodstream directly, causing rapid spread to mast cells throughout the body. This results in simultaneous discharge of large quantities of histamine, leading to severe systemic symptoms. This is why bee and wasp stings can be life-threatening for allergic individuals and why EpiPens are recommended for at-risk people.
