(a) type of malaria: "Falciparum" (Falciparum, F+FG, FG, F+M), "Vivax" (Vivax, Non-F), "Mixed" (F+V, V+FG), or "Other" (Malariae, Ovale); (b) parasite density (graded as number of + sign): "+/2" (< 5 parasites/pl), "+" (5-9 parasites/ pl), "++" (10-100/pl), "+++ or more" (> 100 parasites/pl) or "not informed." According to the plus system, the more plus signs (+), the higher the parasite density; (c) type of detection: "passive detection" or "active detection." Passive detection occurs when a patient comes to the facility for malaria testing; active detection occurs when health professionals search for people with malaria symptoms.
