Symptoms of mosquito bite allergy

The symptoms of mosquito bite allergy can vary from mild to severe and may include:

  • Large, itchy welts or hives at the site of the bite
  • Swelling around the bite area
  • Redness and inflammation
  • Pain or tenderness
  • Warmth at the bite site
  • Fever
  • In severe cases, anaphylaxis, which can cause difficulty breathing, swelling of the throat, rapid heartbeat, and a drop in blood pressure

Causes of mosquito bite allergy

Mosquito bite allergy is caused by an allergic reaction to proteins found in the mosquito’s saliva. When a mosquito bites, it injects its saliva into the skin to prevent blood clotting and facilitate feeding. For individuals with mosquito bite allergy, the immune system mistakenly identifies these proteins as harmful invaders, triggering an allergic response.

Diagnosis

Diagnosing mosquito bite allergy typically involves a physical examination and a review of the individual’s medical history. In some cases, a healthcare provider may recommend allergy testing to confirm the diagnosis.

Treatment

Treatment for mosquito bite allergy focuses on relieving symptoms and preventing future reactions. Options may include:

  • Over-the-counter antihistamines to reduce itching and inflammation
  • Topical corticosteroids to reduce swelling and discomfort
  • Applying cold compresses to the affected area to alleviate pain and swelling
  • Prescription-strength medications for severe reactions
  • Allergy shots (immunotherapy) for individuals with recurrent or severe reactions
