Notes: Shaded areas reflect the range determined by low and high values of the unit cost benchmarks; they do
not reflect uncertainty about future rates of scale-up and scale-down of interventions. The dots in 2012 are actual
numbers reported (when available) multiplied by the unit cost benchmarks; these are not actual expenditures, but
can be thought of as a benchmark for actual expenditures. All numbers expressed in US$ are constant (real) US$,
adjusted to reflect purchasing power in the United States of America in 2015.
As work continues on the third edition of the Disease Control Priorities Project, WHO is
working also on an analysis of the cost-effectiveness of integrated preventive chemotherapy for
helminth elimination and control.
