Mite dermatitis is not terrible and can be prevented and treated. The specific treatment is as follows: 1. Prevention is better than cure, prevention before illness. The actual dermatitis of the mite can be avoided by paying attention to indoor ventilation, bed sheets, bedding, closet and other mite removal work, and paying attention to the exposure of mites before wearing clothes in the new season; 2. Once the mite dermatitis appears, there can be varying degrees of itching, and patients need not be overly alarmed, treatment can be applied to antihistamine drugs, i.e. oral anti-allergy drugs, as well as the use of special treatment dermatitis eczema type ointment can be applied.
