  1. a The numbers in brackets indicate the distribution of blood meals among the different anopheline species (f: blood meals of An. funestus; g: blood meals of An. gambiae; h : blood meals of An. hancocki)
  2. b The human blood rate (HR) expressed as the ratio of blood meals from humans to the total blood samples examined with ELISA.
