High ongoing Onchocerca volvulus transmission (the parasite causing onchocerciasis) was recently documented in Maridi County, South Sudan. To complement community-directed treatment with ivermectin (CDTI) as the main onchocerciasis control strategy, this study team also initiated a community-based vector control method “slash and clear” at the Maridi dam, a breeding site for blackflies that transmit the disease.
The “slash and clear” method was found to be an effective and cheap community-based method to reduce blackfly biting rates. When repeated at least annually together with a high CDTI coverage, this intervention has the potential to considerably accelerate onchocerciasis elimination.
