Population requiring PC 2006-2009: Estimates based on L.Chitsulo et al. / Acta Tropica 77(2000)41-51
From 2010 the estimates of population requiring PC for SCH has been revised. For details on methodology please access: Schistosomiasis: population requiring preventive chemotherapy and number of people treated in 2010 [pdf 873kb]. Weekly Epidemiological Record, N°4, 2012, 87:37–44.

Abbreviations:
SCH – schistosomiasis
PC – Preventive Chemotherapy
Pre-SAC – pre-school age children aged => 1 and < 5 years
SAC – school age children aged => 5 and < 15years
Adults – individuals aged => 15 years.

Definitions:
SAC population requiring PC for SCH annually - estimated number of SAC requiring PC for SCH annually according to the recommended strategy (see below).
Population requiring PC for SCH annually - estimated number of individuals requiring PC for SCH annually according to the recommended strategy (see below).
Programme coverage - proportion (%) of individuals treated as per programme target set.
National coverage - proportion (%) of the population requiring PC for SCH annually in the country that have been treated.

Recommended strategy:
To estimate the population requiring PC for SCH annually, the following model is used:
High risk area – all school-age children and adults required PC.
Moderate risk area – 50% of school-age children and 20% of adults to be treated.
Low risk area – 33% of school-age children to be treated. This is equivalent to treating school-age children twice during their schooling years.
