Mvolo County, an Onchocerciasis Endemic Area in Western Equatoria State, South Sudan: An Entomological Study to Prepare for a "Slash and Clear" Community-Based Vector Control Intervention.

Background: Mvolo in Western Equatoria of South Sudan has been a hotspot for transmission since the 1940s. In Mvolo onchocerciasis is a disease of public health importance, associated with onchocerciasis-associated epilepsy including nodding syndrome.

Methods: We conducted an entomological study to map the breeding sites of blackflies (Simulium damnosum, sens lato) on the river Naam, to allow the removal of vegetation from vector breeding sites, the "slash and clear".

"Slash and Clear", a Community-Based Vector Control Method to Reduce Onchocerciasis Transmission by in Maridi, South Sudan: A Prospective Study.

Background: High ongoing transmission was recently documented in Maridi County, South Sudan. To complement community-directed treatment with ivermectin (CDTI) as the main onchocerciasis control strategy, we initiated a community-based vector control method "slash and clear" at the Maridi dam, a s.l.
