Malaria case-incidence rates by transmission risk category (cases per 1,000 per year) used in estimating the number of cases by Method 2.

aNo observations available so assumed to be the same as that measured in children under 5 by Snow et al [3].bNo observations available so assumed to be half the rate of children 5–14 y by Snow et al [3].cEstimated to be approximately half the rate of rural areas by Korenromp [11] and Carneiro et al [21].dConsidered to be the same as in rural areas by Korenromp [11].IQR, interquartile range.
