Hives Hives, also known as urticaria, is a kind of skin rash with red, raised, itchy bumps.[1] They may also burn or sting.[2] Often the patches of rash move around.[2] Typically they last a few days and do not leave any long-lasting skin changes.[2] Fewer than 5% of cases last for more than six weeks.[2] The condition frequently recurs.[2]
House dust mite The mite's gut contains potent digestive enzymes (notably Peptidase 1) that persist in their feces and are major inducers of allergic reactions such as wheezing. The mite's exoskeleton can also contribute to allergic reactions. Unlike scabies mites or skin follicle mites, house dust mites do not burrow under the skin and are not parasitic.[6]
