Patients detected with Plasmodium vivax (Chloroquine)
Patients with mono-infection of Plasmodium falciparum with ≥ 250 per µl
|
Drug: Chloroquine
Chloroquine will be administered according to body weight at a total dose of 25 mg base/kg over 3 days (10 mg base/kg on Day 0; 10 mg base/kg on Day 1 and 5 mg base/kg on Day 2). Correct drug dosage will be determined using the dosing chart (in accordance Drug: Primaquine For Pf patients, primaquine at 0.75 mg base/kg body weight single dose will be given on Day 3 for Pf patients; For Pv patients primaquine will be withheld for 28 days and will be given after Day 28 follow-up, at 0.25 mg base/kg per day for 14 days. |
- Number of Patients with Early Treatment Failure (ETF) [ Time Frame: Day 1-3 ]
The number of patients with the following criteria based on microscopy results without PCR:
- Development of danger signs or severe malaria on day 1, day 2, or day 3 in the presence of parasitemia;
- Parasitaemia on day 2 higher than day 0 count irrespective of axillary temperature;
- Parasitaemia on day 3 with axillary temperature ≥37.5 ºC;
- Parasitaemia on day 3 ≥25% of count on day 0.
- Number of Patients with Late Clinical Failure (LCF) [ Time Frame: Day 4-28 ]
The number of patients with the following criteria based on microscopy results without PCR:
- Development of danger signs or severe malaria on day 1, day 2, or day 3 in the presence of parasitemia;
- Parasitaemia on day 2 higher than day 0 count irrespective of axillary temperature;
- Parasitaemia on day 3 with axillary temperature ≥37.5 ºC;
- Parasitaemia on day 3 ≥25% of count on day 0.
- Number of Patients with Late Parasitological Failure (LPF) [ Time Frame: Day 7-28 ]The number of patients with the presence of parasitemia on any day from day 7 to day 28 and axillary temperature <37.5 ºC, without previously meeting any of the criteria of Early Treatment Failure or Late Clinical Failure.
- Number of Patients with Adequate Clinical and Parasitological Response (ACPR) [ Time Frame: Day 0-28 ]The number of patients with absence of parasitemia on day 28 irrespective of axillary temperature without previously meeting any of the criteria of Early Treatment Failure or Late Clinical Failure or Late Parasitological Failure.
