Myiasis is a medical condition caused by the infestation of living tissues by the larvae of certain species of flies. These larvae can invade various parts of the body, including the skin, wounds, and even internal organs. Myiasis is most commonly associated with blowflies and flesh flies, which lay their eggs on decaying organic matter or open wounds. The condition can lead to symptoms such as pain, swelling, and infection. Treatment typically involves the removal of the larvae and proper wound care. In severe cases, antibiotics may be necessary to address any secondary infections caused by the infestation.
