EPIFIL predictions of the impact of mass treatment, vector control and their combination on trends in microfilaraemia prevalence. Predictions were made with the EPIFIL simulation model as quantified for Pondicherry (but ignoring acquired immunity), assuming a precontrol microfilaraemia prevalence of 10%. The plot shows the impact of mass treatment alone (5 rounds of annual mass treatment with diethylcarbamazine + albendazole, with a coverage of 80%), vector control alone (assuming a 90% reduction in biting rate during 5 years), and the combination of the two.
