Table 5 Model-predicted required mean number of years of mass treatments for different intervention scenarios for achieving the successful interruption of LF transmission in each of the study sites investigated. The required years of mass treatments were determined by evaluating whether as a result of intervention, the model-predicted community-level mf prevalence had reduced below the mf elimination threshold signifying 95 % probability of elimination for the four scenarios: 1) intervention by annual mass drug administration (MDA) alone; 2) annual MDA with supplemental vector control (VC); 3) biennial MDA alone; and 4) biennial MDA with supplemental VC. VC, where applicable, was implemented at the community coverage of 80 %. The results in this table are shown for three MDA coverages: 60, 80 and 100 %

  1. aThe required years of mass treatments at the MDA coverage of 80 %, without and with vector control, significantly differed within Anopheline and Culicine settings (Kruskal-Wallis test p-values <0.0001)
  2. bTotal variance denotes the overall variance in the required years of mass treatments estimated from all sites within each of the Anopheline and Culicine settings. Data are provided for 80 % coverage for annual and biennial MDAs without and with vector control at 80 % coverage
