Genomic surveillance reveals co-occurrence of Plasmodium falciparum drug resistance variants across diverse transmission settings in Ethiopia.

Co-occurrence of drug resistance variants in Plasmodium falciparum across Ethiopia's diverse transmission settings highlights emerging threats to malaria control.

• Why it matters: Understanding the distribution and co-occurrence of resistance markers is crucial for guiding effective antimalarial policies, especially as resistance threatens elimination efforts in Africa.
• What they did: Genomic analysis of 605 isolates from 15 districts examined key resistance genes and mitochondrial genomes, revealing prevalent haplotypes and expanding PfK13 variants associated with partial artemisinin resistance.
• The result: Findings show co-occurrence of Pfcrt and Pfk13 mutations, with resistant haplotypes near fixation and expanding resistance variants, informing the need for adaptive treatment strategies in Ethiopia.
