Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential patients will be screened for inclusion/exclusion criteria. Once the patient meets all the enrolment criteria and he/she or a parent/guardian (in case of children) consented to participate in the study, the patient will be recruited in to the study. All antimalarial treatment will be given by a study team member under supervision. Thereafter, patients are required to undergo regular clinical reassessment. Blood films for parasite counts will be made on days 2, 3 and 7 and then weekly for the remainder of the follow-up period, i.e. on days 14, 21, 28 (for artemether-lumefantrine and chloroquine) and 35 and 42 (for artesunate-mefloquine).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
N/A. This is a one arm prospective study in which all eligible patients are given test drug.

Summary
Brief summary
Title: Efficacy and safety of artemether-lumefantrine and dihydroartemisinin-piperaquine for the treatment of uncomplicated falciparum malaria, and chloroquine for plasmodium vivax in Kyaing Tone (Eastern Shan State).
Background: Therapeutic efficacy studies will be done in Myanmar to assess the efficacy and safety of artemether-lumefantrine and dihydroartemisinin-piperaquine for the treatment of uncomplicated falciparum malaria, and chloroquine for the treatment of Plasmodium vivax.

The participants will be febrile people above 13 years with confirmed uncomplicated P. falciparum. Patients will be treated with artemether-lumefantrine twice a day over 3 days or dihydroartemisinin-piperaquine over 3 days or chloroquine over 3 days. Clinical and parasitological parameters will be monitored over a 28-day follow-up period to evaluate drug efficacy. The results of this study will be used to assist the Ministry of Health of Myanmar in assessing the current national treatment guidelines for uncomplicated P. falciparum and vivax malaria.
