A 65-year-old Israeli working in Welkait, Ethiopia, not using malaria prophylaxis, developed fever. Malaria rapid detection test was consistent with non-falciparum malaria (plasmodium lactate dehydrogenase+/histidine-rich protein− [LDH+/HRP−]) but microscopy showed typical Plasmodium falciparum. HRP2/3 were negative by polymerase chain reaction. The patient suffered two recrudescence episodes following artemether–lumefantrine and atovaquone–proguanil treatments, and responded to mefloquine treatment.

Plasmodium falciparum and Plasmodium vivax are co-endemic in Ethiopia. This study investigated whether mixed infections were missed by microscopy from a 2017 therapeutic efficacy study at two health facilities in Ethiopia. All patients (N = 304) were initially classified as having single-species P. falciparum (n = 148 samples) or P. vivax infections (n = 156). Dried blood spots were tested for Plasmodium antigens by bead-based multiplex assay for pan-Plasmodium aldolase, pan-Plasmodium lactate dehydrogenase, P. vivax lactate dehydrogenase, and histidine-rich protein 2. Of 304 blood samples, 13 (4.3%) contained both P. falciparum and P. vivax antigens and were analyzed by polymerase chain reaction for species-specific DNA. Of these 13 samples, five were confirmed by polymerase chain reaction for P. falciparum/P. vivax co-infection. One sample, initially classified as P. vivax by microscopy, was found to only have Plasmodium ovale DNA. Plasmodium falciparum/P. vivax mixed infections can be missed by microscopy even in the context of a therapeutic efficacy study with multiple trained readers.
