- Primary Outcome Measures
Name Time Method Percent of treatment failures (early treatment failure + late clinical failure +late parasitological failure). This is composite primary outcome.<br><br>Enrolled patients will be assessed for parasitological and clinical responses during the 28 days follow-up and treatment outcomes will be classified according to the latest WHO protocol.[At days 1, 2, 3, 7, 14, 21, 28 ]
- Secondary Outcome Measures
Name Time Method Percent of adverse event following treatment of each drugs will be documented. <br>The known adverse events of:<br>Artesunate+amodiaquine are abdominal pain, asthenia, cough, diarrhoea, dizziness, insomnia, loss of appetite, nausea, vomiting.<br>Atemether+lumefantrine are abdominal pain, asthenia, cough, diarrhoea, dizziness, fever, headache, joint and muscle pain, loss of appetite, rush, nausea, vomiting.<br><br>Parents or guardians of all enrolled children will be asked routinely about previous symptoms and about symptoms that have emerged since the previous follow-up visit. When clinically indicated, patients will be evaluated and treated appropriately. All adverse events will be recorded on the case report form.[At days 1, 2, 3, 7, 14, 21, 28];Prevalence of artemisinin resistance molecular markers (K13).<br>Parasite DNA extracted from the dried blood spots will be analyzed by PCR and sequencing for the presence of K13 (molecular marker for artemisinin resistance).[At day 0 (prior to treatment]
