  1. HVUSqPCR, high volume ultra-sensitive real time polymerase chain reaction; Hb, haemoglobin; g/dL, grams per decilitre; Pf, P. falciparum, mixed more than one Plasmodium species identified; Plasmodium spp., Plasmodium species was not identified; Pv, P. vivax
  2. aNegative = participants without evidence of parasitaemia by HVUSqPCR
  3. bHVUSqPCR assay could not be performed because sample size was not sufficient or other technical reasons
