Stinging insects, which are responsible for the majority of cases of severe allergy (anaphylaxis) to insects, belong to the group of membranous winged insects, such as bees, ants and wasps, which often sting as a defensive response.
Insect sting results in local symptoms in the majority of cases as a result of substances in the venom, which is released by the insect in the body of the stung person. In a small part of people, an allergic reaction may develop, such as severe allergy (anaphylaxis), which may be fatal.
1. Local reaction:
In this type. symptoms appear in and around the location of the sting, and are usually mild and incidental. This type is of two categories:
2- Severe reaction (anaphylaxis)
The effect extends beyond the location of the sting to several organs of the body, and varies from one person to another. It may include:
Sever allergy to insect sting or bite does not increase the incidence of other allergies such as asthma, hay fever or allergies to any type of food or medicine.
Severe reactions are more common among adults, while 70% of allergic reactions in children are local.
Persons who have anaphylaxis shall always have adrenaline autoinjector. In case of being stung, one shall take the injection immediately and go to the emergency department. Allergic persons shall be examined by an allergist to determine whether they need an immunotherapy to reduce the likelihood of future Anaphylaxis.
Immunotherapy: The person is injected with the same allergens (venoms), in very small quantities, every month to three months, and for a period from three to five years. This allows the body to be familiar with the venom, forming a natural immunity against it. The success rates of immunotherapy in protection from an allergic reaction is very high.
