Primary Outcome Measures:
  • Comparative efficacy. [ Time Frame: 4-5 months ] [ Designated as safety issue: No ]
    Comparative rates of malaria recurrence between the 2 and 3 day DP regimens at 42 days after treatment of malaria infection, diagnosed by positive PCR-corrected malaria microscopy.

Detailed Description:

This is an active observational Cohort Study of malaria epidemiology with a nested two arm, randomized, open label Treatment Study comparing the efficacy, safety, tolerability and pharmacokinetics of a two versus three day course of Dihydroartemisinin-Piperaquine (DP) for those developing uncomplicated malaria. At the conclusion of the Cohort Study, a subset of volunteers with documented exposure to Plasmodium vivax during the study will be treated with primaquine as presumptive anti-relapse therapy directed against the exoerythrocytic malaria stages of P. vivax, and followed passively for an additional 6 months.
