  1. *It is recognized that the number of responses for “Number of times diagnosed with malaria = Never” (12) and “Last time diagnosed with malaria = Never” (11) are not equal for Rangers. There was one ranger who reported never having been diagnosed with malaria, but also reported having been diagnosed with malaria in the past year. At the time of data collection, this inconsistency was not identified, and therefore the data is reported here as it was collected
