Kolkata, June 24 (IANS) A 13-year-old boy whose bizarre ailment has a fly-like insect emerging out of him is far from being cured as doctors struggle to detect the source of the parasite. The fully-grown flies, as doctors described the parasites, have been emerging out of Chandan Goswami's genitals and flying off for more than two weeks now. Chandan, now receiving treatment at a state-run hospital in West Bengal's Burdwan district, is said to be suffering from a condition called myiasis, a disease seen mostly in Central and Latin America.
