How<unk>  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. They may invade open wounds and lesions or unbroken skin. Some enter the body through the nose or ears. Larvae or eggs can reach the stomach or intestines if they are swallowed with food and cause gastric or intestinal<unk> . Several different presentations of<unk>  and their symptoms: Syndrome Symptoms Cutaneous<unk>  Painful, slow-developing ulcers or furuncle- (boil-) like sores that can last for a prolonged period Nasal<unk>  Obstruction of nasal passages and severe irritation. In some cases facial edema and fever can develop. Death is not uncommon. Aural<unk>  Crawling sensations and buzzing noises. Smelly discharge is sometimes present. If located in the middle ear, larvae may get to the brain. Ophthalmomyiasis Severe irritation, edema, and pain. Fairly common. Wound Wound<unk>  occurs when fly larvae infest open wounds. It has been a serious complication of war wounds in tropical areas, and is sometimes seen in neglected wounds in most parts of the world. Predisposing factors include poor socioeconomic conditions, extremes of age, neglect, mental disability, psychiatric illness, alcoholism, diabetes, and vascular occlusive disease. Eye<unk>  of the human eye or ophthalmomyiasis can be caused by Hypoderma tarandi, a parasitic botfly of caribou. It is known to lead to uveitis, glaucoma, and retinal detachment. Human ophthalmomyiasis, both external and internal, has been caused by the larvae of the botfly.
