Another large group of vectors are flies. 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 ...
In epidemiology, a disease vector is any living [1] agent that carries and transmits an infectious pathogen such as a parasite or microbe, to another living organism. [ 2 ] [ 3 ] Agents regarded as vectors are mostly blood-sucking insects such as mosquitoes.
Mosquitoes are vectors for a large number of diseases, the large majority being viral in nature. Mosquito-borne viruses fall into four major groups: Bunyavirales , Flaviviridae , Togaviridae , and Reoviridae .
Chagas disease is caused by infection with the protozoan parasite T. cruzi, which is typically introduced into humans through the bite of triatomine bugs, also called "kissing bugs". [4] When the insect defecates at the bite site, motile T. cruzi forms called trypomastigotes enter the bloodstream and invade various host cells. [5]
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. Medical entomologists worldwide are working to combat the known effects in order to improve public health.
The Centers for Disease Control and Prevention issued an advisory on Aug. 16 warning people traveling to areas known to have the Oropouche virus to avoid getting bit by midges and mosquitoes.

This behaviour causes disease or the likelihood of disease that varies with the organism: Chagas disease in humans, dourine and surra in horses, and a brucellosis-like disease in cattle. Parasites need a host body and the haematophagous insect triatomine (descriptions "assassin bug", "cone-nose bug", and "kissing bug") is the major vector in ...
