A community-based vector control intervention "Slash and Clear" implemented in two onchocerciasis-endemic foci in South Sudan.

ABSTRACT:

Background

Despite several rounds of ivermectin treatment, onchocerciasis transmission persists in Mvolo and Mundri West Counties (Western Equatoria State, South Sudan). A community-based "Slash and clear" (S&C) vector control method was recently introduced, but its effectiveness remains unclear.

Methods

Between October 2023 and November 2024, entomological studies were conducted to map blackfly breeding sites along River Naam (Mvolo County) and River Yei (Mundri West County). Following baseline assessment of daily biting rates at multiple catching sites, one round of S&C was implemented at selected intervention sites. Monthly biting rates (MBR) were monitored over a follow-up period of 8-14 months and compared between intervention and control sites.
