Title: A Randomized Trial to Determine the Efficacy and Safety of Coartemether and Artekin for the Treatment of Acute Falciparum and Vivax Malaria in Timika, Papua
Brief Summary: This open randomized, parallel group, 6 week trial in two rural outpatient clinics will compare the safety and efficacy of a six dose coartemether regimen with 3 dose artekin regimen for the treatment of acute, uncomplicated falciparum and vivax malaria in adults and children (\>10kg).

C: Inclusion Criteria:

* Males and Females aged between 6 months and 59 months inclusive.

* Body weight of 5 Kg and above.
* Microscopically confirmed, monoinfection of Plasmodium falciparum (parasitaemia ≥ 2,000/μL to 200,000/μL).
* Fever (axillary temperature at ≥ 37.5°C) or history of fever in the previous 24 hours.
* Haemoglobin value ≥ 7.0 g/dl;
* Signed (or thumb-printed whenever parents/guardians are illiterate) informed consent by the parents or guardians. Note the informed consent will be asked only at recruitment and will cover the whole period of the study, including second active follow up and passive case detection.
