Example of a mosquito larval surveillance component in a municipal monthly report template. A. The overall data entry table in which each row corresponds to one, or occasionally two (see bottom row for example of a very large neighbourhood) folders, each containing 4 or 5 sequential weekly ward summary forms and respective sets of CORPs larval surveillance forms. Note that weeks overlapping two months are assigned to specific calendar months in advance so that each operational month has a predefined start and end date, spanning exactly 4 or 5 weeks. B. A typical automatically generated chart summarizing the observed distribution of larval habitat abundance and mosquito occupancy in one ward.
