Description of ivermectin treatment in the areas where cost data were obtained in Ghana.

a<p>For the Wenchi and Kpandai districts, therapeutic coverage estimates were taken directly from national records pertaining to the last treatment round of 2010. For the Pru and Kintampo North districts, coverage estimates were derived from an average of two treatment rounds (the last round of 2010 and the first round of 2011).</p>b<p>A biannual strategy is used in 15 of 76 (20%) communities in the sampled sub-district, whereas the remainder 80% receive treatment annually. Therefore, the costs are likely to reflect more closely those of annual rather than biannual distribution.</p
