Evidence of artemisinin partial resistance in northwestern Tanzania: clinical and molecular markers of resistance.

ABSTRACT:

Background

In 2021, nationwide malaria molecular surveillance revealed a high prevalence of a validated artemisinin resistance marker, the kelch13 (k13) Arg561His mutation, in the Kagera region of northwestern Tanzania. We aimed to investigate the efficacy of artemether-lumefantrine and artesunate-amodiaquine and to confirm the presence of artemisinin partial resistance (ART-R) in the Karagwe district of this region.

Methods

This single-arm, therapeutic efficacy study was carried out at the Bukangara dispensary in the Karagwe district of the Kagera region in northwestern Tanzania. Eligible participants were aged between 6 months and 120 months, had confirmed Plasmodium falciparum asexual parasitaemia, and met other inclusion criteria according to WHO's standard protocol. Par
