Elderly and debilitated individuals of both sexes with exposed chronic wounds or ulcers are at a higher risk of suffering from this infestation. Furunculoid and subcutaneous forms may affect any part of the body, but in children the scalp is a commonly affected site. Chronic ulcers of the lower legs and feet represent a predisposing factor and myasis often complicates severe infections by bacteria or fungi. Larvae feed on tissue debris and may not cause discomfort or symptoms at all. Cases are observed throughout the year in tropical regions where the standards of hygiene, nutrition, and general health are poor. The diagnosis is based on clinical suspicion and physical findings. This problem is rarely seen in the returning traveller.
