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.
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.
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]
Here are some of the mot common bug, insect and spider bites you might be dealing with — and insect bite pictures to help you figure out which bug is responsible. Tick bites Bull's eye rash (TODAY)
How myiasis affects the human body depends on where the larvae are located. Larvae may infect dead, necrotic (prematurely dying) or living tissue in various sites: the skin, eyes, ears, stomach, and intestinal tract, or in genitourinary sites. [5] They may invade open wounds and lesions or unbroken skin. Some enter the body through the nose or ...
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 ...
Protozoan infections are responsible for diseases that affect many different types of organisms, including plants, animals, and some marine life. Many of the most prevalent and deadly human diseases are caused by a protozoan infection, including African sleeping sickness , amoebic dysentery , and malaria .
