- Primary Outcome Measures
Name Time Method 1. To measure the clinical and parasitological efficacy of artesunate and sulfadoxine-pyrimethamine among patients aged above six months suffering from uncomplicated falciparum malaria and chloroquine for vivax malaria, by determining the proportion of patients with:<br>1.1. Early Treatment Failure (ETF)<br>1.2. Late Clinical Failure (LTF)<br>1.3. Late Parasitological Failure (LPF)<br>1.4. Adequate Clinical and Parasitological Response (ACPR) <br>As indicators of efficacy<br>2. To differentiate recrudescences from new infections by the Polymerase Chain Reaction (PCR) analysis<br>3. To evaluate the incidence of adverse events
