aPopulation estimates taken at midpoint of the time interval.
bEstimates for the proportion of patients with malaria attending the public provider and thus who will have been detected by the surveillance network were derived from household surveys conducted in 2005 and 2013, reported previously [28].
cIncludes patients attending the new RSUD hospital but excludes community cases due to surveillance finishing in December 2009.
dIncludes 120 cases of P. ovale.
