Visualisation via heat map of the estimated time until transmission is interrupted (prevalence below 0.1%) for a range of coverages and transmission levels as a result of three years of mass interventions for a) MDA alone for three years or b) mass vaccination with MDA for each year, up to three years. Estimates of malaria interruption time for a range of yearly intervention coverage and initial R₀, with colour indicating time to interruption with the darker the colour indicating earlier interruption. No interruption occurred after 4 years as interventions ceased by year 3. No interruption of transmission was observed in the vaccination only strategies.
