There are many insects (and other arthropods) that affect human health. These arthropods include Diptera, Hemiptera, Phthiraptera, and Siphonaptera. They can parasitize, bite, sting, cause allergic reactions, and/or vector disease to humans. It can be impossible to know the full impact that insects and other arthropods have on human health.
Sandfly species transmit the disease leishmaniasis, by acting as vectors for protozoan Leishmania species, and tsetse flies transmit protozoan trypansomes (Trypanosoma brucei gambiense and Trypansoma brucei rhodesiense) which cause African Trypanosomiasis (sleeping sickness). Ticks and lice form another large group of invertebrate vectors.
