This is a bi-centric phase IIIb, randomized, open label, 3-arm clinical trial performed to investigate the impact of retreatment with an Artemisinin-Based Combination (ACT), for example Arthemeter-Lumefantrine (AL) in Uganda (Ug) and artesunate-amodiaquine (ASAQ) in RDCongo, on malaria incidence and its potential selection of resistant strains.

Patients will be followed-up for efficacy and safety during 42 days after treatment with the first line therapy recommended by the national authorities(arthemeter-lumefantrine in Uganda and artesunate-amodiaquine in RDCongo) and retreated the patients either with the same ACT or an other ACT or oral Quinine + clyndamicin.

The investigators hypothesize that (re)treatment with the first line ACT treatment beyond 14 days is as efficacious as any other rescue treatment, without the risk of selecting drug resistant strains.

Primary Outcome Measures:
  • Late Parasitological Failure [ Time Frame: Day4-Day28 ]
    Parasitaemia after day 3 in the absence of fever (axillary temperature <37.5°C)

Secondary Outcome Measures:
  • PCR unadjusted efficacy [ Time Frame: Day 28 days ]
    Proportion of children without (PCR not adjusted) treatment failure (TF28U): all treatment failures detected during the active follow up, regardless of genotyping.

  • Day 42 clinical efficacy [ Time Frame: Day 42 ]
    All clinical treatment failures detected during the 42 days follow up for the first line treatment, with and without PCR adjustment. As no active monitoring of parasitaemia after day 3 is planned this includes ETF and LCF following WHO criteria.

  • Change in Fever clearance time (FCT) [ Time Frame: Day 0, Day 1, Day 2 ]
    The time (in days) from the time of randomization to the first two consecutive measurements on 2 different days of axillary temperature below 37.5°C.

  • Change in Asexual parasite clearance time [ Time Frame: Day 0, Day 1, Day 2 ]

    Asexual parasite clearance time is defined as the time (in days) from time of randomization to 2 consecutive negative blood slides (collected at different days). The time to the event will be taken as the time to the first negative slide.

    5. Gametocytaemia (prevalence and density) at day 7, 14, 21 and 28 after treatment.

  • Hb changes [ Time Frame: Day 0, Days 14 and Day 28 ]
    Variation in Hb level between two measurements.

  • Early Treatment Failure [ Time Frame: Day0-Day3 ]
    Development of danger signs or severe malaria on Day 0, Day 1 Day 2 or Day 3, in the presence of parasitaemia Parasite density on Day 2 > Day 0 count, irrespective of axillary temperature Presence of parasitaemia on Day 3 with fever (axillary temperature ≥ 37.5°C) Parasitaemia on Day 3 ≥ 25 % of count on Day 0.

  • Late Clincial Failure [ Time Frame: Day0-Day28 ]
    Development of danger signs or severe malaria after Day 3 in the presence of parasitaemia Presence of parasitaemia and fever on any day from Day 4 to Day 28

  4. Signed (or thumb-printed whenever parents/guardians are illiterate) (second) informed consent by the parents or guardians. Note: the informed consent will cover the whole period of the study, including additional active follow ups

Exclusion Criteria:
