Clinical Causes: Infestation with Dermanyssus gallinae (poultry red mite), often associated with poultry environments. Contact with Liponyssoides sanguineus, also known as the house mouse mite, which may infest rodent habitats. Inoculation by trombiculid mites (chiggers), which are tiny mite larvae that latch onto the skin in various outdoor environments. Exposure to infested environments such as poultry farms, rodent habitats, or outdoor grassy areas where mites are prevalent. Poor hygiene or sanitation that facilitates mite proliferation. Close contact with infested animals or environments.

Key Symptoms: Intense itching and scratching of affected skin areas. Redness and inflammation of the skin, often in clusters or linear patterns. Small bites or itching papules detectable on the skin. Secondary skin infections resulting from scratching and skin breakdown. In certain cases, blistering or oozing lesions. Localized swelling and discomfort, especially in areas exposed during outdoor activities.

Diagnosis Path: Diagnosis of other acariasis involves a detailed medical history and physical examination focusing on skin lesions and exposure history. Identification of mite presence may sometimes be achieved through skin scrapings, dermoscopy, or examination of affected clothing or bedding. Laboratory analysis is rarely necessary but may be used in uncertain cases. Immune response tests are not routinely used for diagnosis. Knowledge of recent outdoor activities or contact with infested environments helps guide diagnosis.

Treatment Protocols: Application of topical antiparasitic agents or corticosteroids to reduce inflammation and itching. Use of antihistamines to control allergic reactions and itchiness. Thorough cleaning of affected areas, including laundering bedding, clothing, and household items to remove mite residues. Avoidance of infested environments during active mite seasons. Proper hygiene and hygiene practices to minimize the risk of reinfestation. In some cases, healthcare providers may recommend topical or oral medications if the infestation is severe or persistent.
