The age, gender, occupation and bed-net use distribution is shown for the surveyed population (representing 7.7%, 1.9% and 4.0% of the population covered by the public health system in Sampovloun, Koh Kong and Preah Vihear, respectively), and for the individuals testing positive for Plasmodium by microscopy. P values from a univariate analysis of malaria prevalence distribution in each area are also shown.
