Primary Outcome Measures:
  • To confirm the hypothesis that a dose of 2000 mg Azithromycin plus 600 mg chloroquine base each day for three days is highly efficacious for the treatment of symptomatic, uncomplicated P. falciparum. [ Time Frame: For the duration of the study ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Asexual P. falciparum parasite clearance time [ Time Frame: For the duration of the study ] [ Designated as safety issue: No ]
  • Fever clearance time [ Time Frame: For the duration of the study ] [ Designated as safety issue: No ]
  • An assessment of the safety and tolerability of the treatment regimen [ Time Frame: For the duration of the study ] [ Designated as safety issue: No ]
  • % Early Treatment Failures (ETF) [ Time Frame: For the duration of the study ] [ Designated as safety issue: No ]
  • % Late Treatment Failures (LTF) [ Time Frame: For the duration of the study ] [ Designated as safety issue: No ]
  • Resistance as measured by RI, RII, RIII [ Time Frame: For the duration of the study ] [ Designated as safety issue: No ]
  • Clinical cure rates at 3, 7, 28, and 42 days [ Time Frame: at 3, 7, 28, and 42 days ] [ Designated as safety issue: No ]
  • P. falciparum gametocyte absence rate at 7, 14, 21, 28, 35 and 42 days [ Time Frame: 7, 14, 21, 28, 35 and 42 days ] [ Designated as safety issue: No ]
  • Asexual P. falciparum parasite clearance rate at 7, 14, 21, 35 and 42 days [ Time Frame: 7, 14, 21, 35 and 42 days ] [ Designated as safety issue: No ]
