Figure 4From: Impact of ivermectin on onchocerciasis transmission: assessing the empirical evidence that repeated ivermectin mass treatments may lead to elimination/eradication in West-AfricaPrevalence of microfilariae (mf), community microfilarial load (CMFL), annual biting rate (ABR), and crude annual transmission potential (ATP) against time in the Rio Gêba (C) study area. The thick grey lines at the top indicate the period over which ivermectin mass treatment was given. Note that the top two panels refer to survey villages, and the bottom two panels to capture points.Back to article page
