However, these helminths still exist and raise concerns regarding public health. Stool samples, blood samples, and demographic data were obtained from 307 participants. Stool examination via the formalin-ethyl acetate concentration technique (FECT) and agar plate culture (APC) was performed, and parasite eggs and larvae were identified microscopically by experienced technicians. Of 307 individuals, 91 (29.6%) were positive for intestinal helminths and protozoans according to FECT and APC testing.

Namibia has experienced a greater than 90% reduction in malaria cases since the introduction of these therapies in 2005. However, their efficacy has not been routinely monitored, with malaria outbreaks regularly reported since 2016. The recent emergence of artemisinin partial resistance in Africa has highlighted the role of malaria molecular surveillance in complementing efficacy studies. This cross-sectional genomic surveillance study was nested within Namibia's routine surveillance system and aimed to determine the prevalence of antimalarial drug resistance markers in northern Namibia. Dried blood spots (DBS) and epidemiological data were collected from patients with confirmed Plasmodium falciparum cases who presented at health facilities in the highest malaria-burden regions (Zambezi, Kavango East, Kavango West, Ohangwena, and Omusati) from April to September 2023. Twelve genes associated with resistance to seven antimalarial drugs were genotyped from 264 DBS using multiplexed targeted amplicon sequencing. Multiple kelch 13 mutations associated with artemisinin partial resistance were identified: the P441L candidate marker was the most abundant, at 33.2%, and the P574L and A675V validated markers were observed in 1.2% of samples. The chloroquine resistance transporter C72/V73/M74I/N75E/K76T haplotype was observed in 1% of samples, whereas the multidrug resistance protein 1 N86 genotype, which is associated with reduced susceptibility to lumefantrine, was found in all samples.
