Nasty little buggers, which I did not know about... So I visited my good friend, Google. Here is what I found:
(Skin maggot fly,Tumbu fly, putsi fly)
A species of fly isolated from patients with travel history include the human bot fly (Dermatobia hominis), the Tumbu fly (Cordylobia anthropophaga), the Lund's fly (Cordylobia rodhaini) and the New World screw worm fly (Cochliomyia hominivorax).
Both species of Cordylobia are found only within the African continent. The Tumbu fly is a common blowfly of tropical Africa, south of the Sahara Desert. The Lund's Fly is a blowfly rarely involved in human myiasis (Zumpt, 1965); it is found in rainforest areas of tropical Africa, from Senegal to Central Africa and south to Angola and Rhodesia, usually associated with rodents. Females of these two Cordylobia species deposit their eggs below the surface of sandy soil and occasionally on clothing that has been tainted with traces of faeces or urine. Any disturbance of the soil surface is met with an immediate response from the young larvae that wriggle to the surface in order to penetrate the skin of the host. The life cycle of the two Cordylobia species takes 10-12 days to develop to the prepupal stage, when it leaves the host to pupate. Within this time the patient will endure pain and intense itching from the developing lesion.
The New World screw worm (C.hominivorax), is a species of maggot that can burrow into the flesh of humans, wild and domestic animals. Where it was once more widespread in its distribution it is now generally limited to Central and South America (Kettle, 1995). Females of this fly species deposit their eggs on the edges of wounds, sores and healthy mucous membranes. After burrowing into the hostâ€™s tissue, the young larvae feed on living tissue for 4-8 days. This causes extreme pain and disfunction to the host from the festering wounds before the maggot matures to the prepupal stage when it leaves the host.
Clinical Presentation & Treatment
Infections with myiatic flies start out as itchy sores that then develop into painful boil-like lesions, which often ooze. Most of these cases of human myiasis are uneventful, but patients should be monitored for additional and subsequent lesions as the development of the maggots is not synchronous or isolated, and their growth phase may be prolonged. Treatment of this condition can be undertaken by forcing the maggots to the skin's surface by cutting off their air supply. An application of Vaseline or similar material will encourage the maggot to move towards the surface exposing more of the maggot's body that can then be extracted. A local anaesthetic and incision to extract the maggot is another common method of treatment.
