Allergic reactions to mite bites typically cause skin symptoms such as redness, swelling, erythema, papules, and even blisters or skin lesions. The affected skin area may become inflamed, appear reddened, and be accompanied by intense itching. In severe cases, the rash may spread systemically, accompanied by systemic symptoms such as diarrhea, headache, and fever. Approximately one week later, the rash will gradually subside and the itching will diminish, although localized skin pigmentation may remain.

These symptoms occur because mite bites may introduce secretions, excretions, or debris from the mites' bodies, which can trigger allergic reactions in the body. This leads to capillary dilation, edema within the skin and mucous membranes, and the release of inflammatory mediators. Therefore, for allergic reactions following mite bites, timely medical consultation is recommended, along with treatment and care under a physician's guidance. Additionally, maintaining personal hygiene and regularly airing bedding can help reduce mite proliferation and prevent bites.
