Coverage area was calculated using 15 km radius buffers around geographical coordinates of the community-based malaria posts, clipped using administrative boundaries around the Malaria Elimination Task Force area so that the buffer was not allowed to extend into areas not within the target area (ie, Thailand or the Thandaung township). IR=incidence rate.
