Diseases carried

Allergens (triggers) from dust mites can come from their body parts, saliva, or their droppings.

Allergic diseases from exposure to dust mites can include asthma, hayfever, conjunctivitis, sinusitis, eczema or any combination of these. They have also been linked with conjunctivitis, urticaria, dermatitis, anaphylaxis, hypersensitive pneumonia, angioedema, extrinsic allergic alveolitis, allergic and migraine headache, and certain gut disorders in which IgE is involved.

Of the 22 known allergens from dust mites, seven are active digestive enzymes and several are classified as unknown.
