Notes: Shaded areas reflect the range determined by low and high values of the unit cost benchmarks; they do<br />

not reflect uncertainty about future rates of scale-up and scale-down of interventions. The dots in 2012 are actual<br />

numbers reported (when available) multiplied by the unit cost benchmarks; these are not actual expenditures, but<br />

can be thought of as a benchmark for actual expenditures. All numbers expressed in US$ are constant (real) US$,<br />

adjusted to reflect purchasing power in the United States of America in 2015.<br />

can be reduced. The investment target for preventive chemotherapy (delivery excluding<br />

medicines) during 2015–2020 is about US$ 59 million (US$ 51–67 million) per year. The<br />

investment target falls to US$ 55 million (US$ 47–64 million) per year during 2021–2030,<br />

or US$ 31 million (US$ 27–36 million) by 2030.<br />

As work continues on the third edition of the Disease Control Priorities Project, WHO is<br />

working also on an analysis of the cost-effectiveness of integrated preventive chemotherapy<br />

for helminth elimination and control.<br />
