The story of bee venom and allergies

When a person is bitten by a bee for the first time, anyone can experience transient pain or swelling. In a small number of people, a bee sting twice and three times can cause an allergic reaction called an antigen antibody reaction, makes you feel sick, and in the worst case, life-threatening. These symptoms are called anaphylactic shock, and usually occur within one hour of being bitten by a bee, usually within 10 to 30 minutes.
If you have been bitten by a bee, be careful not to get stuck.
Bee bite accidents are concentrated during the month from late August to mid-September, accounting for 70% of annual sting accidents.
