Calculation steps for estimating the cost of a single mass drug administration (MDA) round.

The table displays the source data and describes all steps that were taken to estimate the cost of a single MDA round per 100,000 eligibles.n.a. = not applicable.aThe term base year refers to the year in which cost were originally measured (1996 for India, 2002 for West Africa).bCalculated from 1), 3) and 4), assuming that drugs (50 mg DEC tablets) were purchased for all eligible persons.cFor India: cost of DEC (50-mg tablets; 5.2 tablets p.p. on average; 0.026 US$ p.p. on average) were subtracted.dCorrection for inflation, using the annual deflators as published by the World Bank [24], i.e. the rate of price change in the economy as a whole. The amount under 6) was first converted back to local currency using the base year conversion rate. Then we applied the correction for inflation between the base year and 2009. The new amount was reconverted into US dollars using the 2009 conversion rate. Average annual inflation in India was about 5% between 1996 and 2009. The average annual inflation between 2002 and 2009 in Burkina Faso was 9%.eWe assume that sensitization efforts in India are intensified to achieve higher coverage, as studied elsewhere [25], [26]. Associated extra costs (for personnel and supplies) would be 0.009 US $ per person in 2002, or 0.015 US$ per eligible if adjusted to 2009 values.fVolunteer remuneration has changed. In 2002, volunteers were paid for 2 days of training only, not distribution. By 2010 Burkina volunteers were remunerated for about 2.5 days training and 7 days distribution; the daily rate remained the same.
