|Plasmodium spp.||Microscopic examination||PCR|
|P. vivax||140 (90.9)||120 (74.1)|
|P. falciparum||4 (2.6)||4 (2.5)|
|P. falciparum–P. vivax||0||38 (23.4)|
|P. ovale||10 (6.5)||0|
|Proportions of positive results||154/453 (34.0)||162/453 (35.8)|
*Results are expressed as the number of malaria-positive samples and the proportions of malaria species among 154 samples positive by microscopic examination and 162 samples positive by PCR. Proportions of positive results denote the number of malaria-positive samples among all tested samples (n = 453). Rapid diagnostic tests were positive in a total of 108/453 (23.8%) patients and detected 92/108 (85.2%) non–P. falciparum only (i.e., P. vivax, P. ovale, and/or P. malariae) and 16/108 (14.8%) P. falciparum present (P. falciparum with or without P. vivax). PCR did not detect any P. ovale or P. malariae.
1Preliminary results of this study were presented at the 7th Multilateral Initiative for Malaria (MIM) Pan African Malaria Conference, April 15–20, 2018, Dakar, Senegal.
