Mosquito bite allergy symptoms mainly include localized redness, swelling, itching, pain, and possible blisters and rashes. These symptoms are caused by various antigenic components present in the mosquito's saliva that is injected during a bite, leading to allergic and inflammatory reactions in the skin. Specifically, redness and swelling appear rapidly at the bite site, accompanied by significant itching. In severe cases, blisters, scratch marks, blood crusts, and even skin infections may occur. Some individuals may also experience systemic reactions such as fever, headache, and fatigue. If symptoms are severe or persist, prompt medical attention and professional treatment are recommended.
