This article contains a list of insect-borne diseases. They can take the form of parasitic worms , bacteria , protozoa , viruses , or the insects directly acting as a parasite. Insect-borne diseases
Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms. Either via their bite, as in the case of malaria spread by mosquitoes, or via their faeces, as in the case of Chagas' Disease spread by Triatoma bugs or epidemic typhus spread by human body lice. Many invertebrates are responsible for transmitting diseases.
Gongylonema pulchrum is the only parasite of the genus Gongylonema capable of infecting humans. Gongylonema pulchrum infections are due to humans acting as accidental hosts for the parasite. There are seven genera of spirudia nematodes that infect human hosts accidentally: Gnathostoma, Thelazia, Gongylonema, Physaloptera, Spirocerca, Rictularia.
What they look like: Mosquitoes leave itchy bumps on the skin that may swell and become red. These reactions typically appear within minutes after a bite, the Mayo Clinic says.In some people, the ...
Some people suffer from “skeeter syndrome,” which causes the bites to grow into painful, swollen welts. Mosquitoes do carry a risk of certain diseases like West Nile and Zika, so monitor for ...
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 ]
Scarabiasis, or "beetle-disease", is a condition where beetles temporarily infest the digestive tract of other animals. It can also affect humans, and despite being a rare phenomenon, [1] it is the second most important insectal disease in humans after myiasis, which is caused by the larva of flies. The term is commonly used as a synonym of ...
Leishmaniasis is a wide array of clinical manifestations caused by protozoal parasites of the Trypanosomatida genus Leishmania. [7] It is generally spread through the bite of phlebotomine sandflies, Phlebotomus and Lutzomyia, and occurs most frequently in the tropics and sub-tropics of Africa, Asia, the Americas, and southern Europe.
