Onchocerciasis control in the WHO African Region
AbstractAfrica accounts for 99% of the river blindness cases in Africa and South America. The WHO African Region has recorded unprecedented success in the control of onchocerciasis (river blindness). However, the Region risks the loss of over US$ 2.5 billion investments from endemic countries and their development partners. Countries which have maintained active control and surveillance of disease also risk the loss of significant economic development and alleviation of poverty. 2. Due to conflict, irregular budgetary allocation from national financing mechanisms, the coendemicity of onchocerciasis and loiasis, and poor surveillance, 13 countries still have high disease prevalence and reservoirs of Onchocerca volvulus infection. There is danger of resurgence of disease because of the long flight range of the vector blackfly known to transmit cross-border infection.
