Table 1. Description of ivermectin treatment in the areas where cost data were obtained in Ghana.

Region	District	Treatment Frequency	Number of Persons Treated Per Year	Overall Therapeutic Coverage (%)^a	Size (km²)
Brong-Ahafo	Wenchi	Annual in all communities	27,881	90.43	3,494
Brong-Ahafo	Kintampo North	Biannual in all communities	57,802	82.10	5,108
Brong-Ahafo	Pru	Biannual in all communities	68,506	88.08	2,195
Northern	Kpandai	Annual in 122 (55%) and biannual in 100 (45%) of 222 communities^b	90,183	79.10	1,772

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).

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.
