programs for control of onchocerciasis and lymphatic filariasis have paid little attention to mansonelliasis. Despite the high prevalence of M. perstans in areas of tropical Africa, such as Uganda, the Congo, the Republic of Cameroon, and Gabon, no vector programs have been instituted for any of the mansonelliasis-causing parasites. Major reasons for this lack of attention are that M. perstans infections prevail in poor, rural populations and that infection with the parasite has not been linked with a clear and distinct medical picture. Much of the information regarding M. perstans has been obtained as a byproduct from studies of other filarial parasites. Mansonelliasis can thus be classified as one of the most neglected among the neglected tropical diseases. Culicoides midges are small enough to pass through screening or mosquito nets, so these would not be helpful. Protection of visitors to endemic areas can be achieved through the use of insect repellents.
