Genetic relatedness of Cambodian <i>Plasmodium falciparum</i> isolates is driven by geography and occupation

High overall IBD sharing may reflect a combination of recent elimination efforts and expansion of drug-resistant lineages. Substantial differences in relatedness between provinces underscore the role of geography in shaping relatedness patterns. Lower relatedness among mixed-occupation pairs compared to farmer pairs suggests potential occupation-specific transmission sources and supports tailoring interventions to local micro-epidemiologic factors.
