OBJECTIVES: This study was performed to identify and characterize circulating Plasmodium species in three provinces of Mindanao approaching malaria elimination. METHODS: Rapid diagnostic tests (RDT), microscopic examination, and PCR were used to detect malaria parasites. PCR-positive isolates were genotyped for polymorphisms in loci of interest. RESULTS: A total of 2639 participants were surveyed in Mindanao between 2010 and 2013. Malaria prevalence by PCR was 3.8% (95% confidence interval (CI): 2.7-5.2%) in Sarangani, 10% (95% CI: 7.7-12.7%) in South Cotabato, and 4.2% (95% CI: 3.2-5.6%) in Tawi-Tawi. P. falciparum and P. vivax were identified in all three provinces, and there was one case of P. malariae in South Cotabato. RDT was inferior to PCR for detecting asymptomatic P. falciparum and P. vivax. In Tawi-Tawi, microscopy failed to identify 46 PCR-positive malaria infections. The presence of pfcrt haplotypes CVMNK, CVIET, and SMNT (codons 72-76), pfmdr1 haplotype NFSND (codons 86, 184, 1034, 1042, 1246), and pvmdr1 haplotype NFL (codons 91, 976, 1076) was confirmed in Mindanao. CONCLUSIONS: Asymptomatic Plasmodium infections persisted in local communities between 2010 and 2013. PCR successfully identified subpatent malaria infections, and can better characterize malaria epidemiology in communities seeking malaria control and elimination at the local level.
