  1. Values in table are given as the number (n) of Plasmodium-positive samples with the percentage of positive samples for each species according to season, site and location given in parentheses
  2. ELISA Enzyme-linked immunosorbent assay
  3. aPlasmodium was detected using an ELISA targeting P. falciparum circumsporozoite protein
  4. bThe PCR assay used primers that target a subunit of the cytochrome c oxidase I gene (COX1) located in the Plasmodium mitochondrial genome. (Parentheses indicate percentages of the plasmodium positivity)
