Elements of Future Treatment Strategies

Type Strategy Code Explanation Remarks
Future MDA A65, A80 7 y of aMDA with ivermectin, starting in 2019 with the last treatment given in 2025, covering 50%, 65%, or 80% of the population, respectively. aMDA is provided in month 6, just before peak transmission season. aMDA is not considered in settings with a history of bMDA; for settings with a history of control, we do not consider strategies involving a reduction in coverage or treatment frequency.
B65, B80 As above, but with bMDA. Treatment is provided in months 6 and 12 (14 treatment rounds over 7 y).
Q65, Q80 As above, but with quarterly MDA. Treatment is provided in months 3, 6, 9, and 12 (28 treatment rounds).
Future VC VC5, VC15 VC through ground-based larviciding, continued for 5 or 15 y, respectively. VC starts 2 y later than future MDA (from January 2021 onward) to allow for necessary preparations; VC ends in the same year as MDA if continued for only 5 y, and 10 y later with the 15-y duration.
Evaluation E Elimination is predicted to have been achieved with the current strategy used to 2018; evaluation should be scheduled, and until then, the current strategy should be continued (with at least 65% treatment coverage). Only considered in settings with a history of annual or bMDA, to check whether additional interventions are needed at all.

Abbreviations: aMDA, annual mass drug administration; bMDA, biannual mass drug administration; MDA, mass drug administration; VC, vector control.
