The bodies, feces, and saliva of dust mites can trigger what?

• A. Asthma and allergic reactions
• B. Hypertension
• C. Diabetes
• D. Skin infection

Answer: (A)

Dust mite allergens are proteins found in the mites’ bodies, feces, and saliva. When these airborne proteins are inhaled, they can trigger an IgE-mediated immune response in people who are sensitive. This response inflames the airways and nasal passages, leading to asthma symptoms such as wheezing, coughing, and shortness of breath, as well as allergic reactions like rhinitis. While mites can aggravate skin conditions such as eczema in some individuals, the primary health effect described here is related to respiratory allergy and asthma, not hypertension, diabetes, or skin infections. Reducing indoor humidity, using allergen–proof bedding, and regular cleaning help lower exposure and lessen symptoms.
