Emerging artemisinin resistance is a major concern

Parasite resistance to artemisinin, the core compound in WHO-recommended combination treatments for uncomplicated malaria, has been detected in 5 countries of south east Asia: Cambodia, Laos, Myanmar, Thailand and Viet Nam. However, artemisinin-based combination therapies remain effective in almost all settings, as long as the partner drug in the combination is locally effective.
