Distribution of the population according to the number of prior infections experienced. The susceptible population distribution is plotted for each endemic setting prior to (shaded distribution) and immediately following (black line) 10 MDA rounds. The effect of the MDA programme is to shift the population distribution to the left (i.e. to lower numbers of prior infections experienced), and this effect is more pronounced as the endemicity declines from hyper–to hypoendemic. Note the axis difference in a compared to b and c
