Predicted relationship between MDA and changes in malaria R 0 . Relative malaria R0 values < 1.0 indicate reduction in transmission potential, values > 1.0 indicate increase in transmission potential, while 1.0 (green line in 6A) indicates no change. A) Ideal situation of 100% coverage with MDA, administered every 7 (black), 14 (blue) or 30 (red) days. B) Average relative R0 for a range of MDA coverage levels (10% to 100%) and treatment regimes (every 7 to 30 days).
