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 .
The World Health Organization (WHO) estimates that 17% of all infectious diseases worldwide were transmitted by arthropod vectors, resulting in over 700,000 deaths annually. [9] The table below lists common arthropod vectors and their associated diseases. The figure below represents endemic areas of common vector-borne diseases.
Protozoan infections are parasitic diseases caused by organisms formerly classified in the kingdom Protozoa. These organisms are now classified in the supergroups Excavata, Amoebozoa, Harosa (SAR supergroup), and Archaeplastida. They are usually contracted by either an insect vector or by contact with an infected substance or surface. [1]
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.
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]
