Description

Myiasis is the parasitic infestation of the skin of a live animal by fly larvae which grow inside the host while feeding on its tissue. Although flies are most commonly curious about open wounds and urine- or feces-soaked fur, some species can create an infestation even on unbroken skin and are known to use moist soil and non-myiatic flies as vector agents for his or her parasitic larvae.

Because some animals cannot react as effectively as humans to the causes and effects of myiasis, such infestations present a severe and continuing problem for livestock industries worldwide, causing severe economic losses where they're not mitigated by act. Although typically a far greater issue for animals, myiasis is additionally a comparatively frequent affliction of humans in rural tropical regions where myiatic flies thrive, and sometimes may require medical attention to surgically remove the parasites.

Treatment of superficial infestation involves removing the larvae by irrigation and by mechanical extraction. Because larvae prey on dead tissue and foreign matter in open wounds, they were sometimes deliberately introduced to supplement surgical removal of dead or diseased tissue and to stop infection.

Epidemology

Some flies attach their eggs to mosquitoes and await mosquitoes to bite people. Their larvae then enter these bites. Other flies’ larvae burrow into skin. These fly larvae are known as screwworms. They can enter skin through people’s bare feet once they rehearse soil containing fly eggs or attach themselves to people’s clothes then burrow into their skin. Some flies deposit their larvae on or near a wound or sore, depositing eggs in sloughingoff dead tissue.

Myiasis are often categorized clinically supported the planet of the body infested, as an example cutaneous, ophthalmic, auricular, and urogenital. Cutaneous myiasis is myiasis affecting the skin. Cutaneous myiasis presentations include furuncular, migratory, and wound myiasis, counting on the sort of infesting larvae.

Myiasis is never acquired within the United States; people typically get the fly larva (maggot) infection once they visit tropical areas in Africa and South America. People traveling with untreated and open wounds are more in danger for getting myiasis.

Causes of Myiasis

Myiasis is infection with the larval stage (maggots) of varied flies. Flies in several genera may cause myiasis in humans. Dermatobia hominis is the primary human bot fly. Cochliomyia hominovorax is that the primary screwwormfly within the New World and Chrysomya bezziana is that the Old World screwworm. Cordylobia anthropophaga is known as the tumbu fly. Flies within the genera Cuterebra, Oestrus and Wohlfahrtia are animal parasites that also occasionally infect humans.

You may have gotten an infection from accidentally ingesting larvae, from having an open wound or sore, or through your nose or ears. People also can be bitten by mosquitoes, ticks, or other flies that harbor fly larvae. In tropical areas, where the fly larva (maggot) infection is presumably to occur, some flies lay their eggs on drying clothes that are hung outside. A lump will develop in tissue because the larva grows. Larvae under the skin may move on occasion. Usually larvae will remain under the skin and not travel throughout the body.
