Rainfall and temporal trend of the percentage of water habitats in drains targeted with community-based environmental management that contained pupae and/or Anopheles larvae from 2005 to 2007. Data are from the Tanzania Meteorological Agency (Rainfall) and the UMCP routine larval inspection. The time trend was obtained by calculating a 3-month moving average of the percentage of water habitats in drains that contained pupae and/or Anopheles larvae from Jan/2005 to Dec/2007.
