How Common is Wasp Allergy?

Those with an allergy to wasp stings may develop a serious allergic reaction called anaphylaxis. The reaction can be life threatening. It is vital to get immediate medical attention.

Anaphylaxis is a serious allergic reaction that affects the airway, circulation, and other body organs. It is caused by IgE antibodies which trigger different cells to break up the allergen. This causes symptoms like hives and trouble breathing. If this happens, an emergency treatment known as an epinephrine auto-injector should be administered immediately.

The reaction usually starts within two hours of a sting. However, some people develop a delayed reaction that can last up to five days. Medical history and other factors can also play a role.

There are two types of reactions to wasp stings: local and systemic. Local reactions are usually mild and occur at the sting site. A cold pack can help to reduce the swelling, and oral antihistamines can be used to reduce the itching.

Systemic reactions are more serious. These reactions occur at the sting site or in other areas of the body. They may also cause nausea and vomiting. They can also lead to a secondary infection and may require antibiotics.

The symptoms of anaphylaxis are similar to those of a bee sting. A raised welt can be visible at the site of the sting. Swelling may extend down the leg or arm and may last for days. A clot may form at the sting site, and it can cause serious damage.
