Table 3 Optimal (and minimum) intervention characteristics required to achieve target results

From: Modelling the impact of larviciding on the population dynamics and biting rates of Simulium damnosum (s.l.): implications for vector control as a complementary strategy for onchocerciasis elimination in Africa

Intervention characteristics Optimal Minimum to reduce DBR by 95% Minimum to delay repopulation or bounce back (to baseline levels) to 200 days after last treatment
