Symptoms of allergy to mosquitoes

Maybe many people in life are allergic to dogs, animal hair, some are allergic to some pollen, and flying dust from plants in the air, but what everyone does not consider is that some people are allergic to mosquitoes. After mosquitoes bite the skin, bumps will appear, but some people will have very serious symptoms, and they will have dermatitis every time they are bitten by mosquitoes.

What you have is clinically called "insect bite dermatitis". Insect bite dermatitis, also known as "insect bite papular urticaria", refers to an inflammatory reaction of the skin caused by bites by insects or arthropods, or contact with the poisonous hairs of insects, which often occurs in exposed parts and around the waist.

Common insects that cause dermatitis include mosquitoes, bedbugs, fleas, mites, midges (small black bugs), wasps, etc. In addition, some caterpillars, such as mulberry caterpillars and stinging caterpillars, can also cause symptoms when their poisonous hairs pierce the skin.

Due to the different types of insects biting the human body and the different physical conditions of the bitten individuals, different skin reactions will occur at the bite site. The general manifestations are edematous papules, wheals, edematous erythema, papules, papulovesicles, petechiae, etc., accompanied by varying degrees of itching, stinging, and burning pain. Regardless of the type of rash, traces of insect bites or bee stings and poisonous hairs can be found in the center of the affected area. The stings and poisonous hairs should be removed as much as possible and the venom sucked out. For insect bite dermatitis caused by mites and fleas, you must take a bath and change into clean clothes before treatment.

Prevention and treatment: Pay attention to personal and environmental hygiene, and change clothes and bedding frequently. You can spray the pot with 1:5000 pyrethroid insecticide to kill bed bugs, fleas, lice and other insects. Once symptoms are found, medication should be taken promptly. Do not drink alcohol or eat spicy food, and go to the suburbs or parks less often. Straw mats should be washed and dried to reduce the number of mites hidden in them and the possibility of insect bites.
