In addition to their roles as vectors of infectious agents, the diverse group of animals that comprise arthropods may indirectly or directly cause injury that requires diagnosis and treatment. Such injuries include itching, dermal necrosis, anaphylaxis, and systemic toxicosis. The ubiquity of arthropods implies that they may be a frequent cause for clinical attention; reducing exposure is often sufficient to prevent or treat disease.
