Primary | treatment failure | The efficacy of the treatment will be based on clinical and parasitological evaluation of the participants, conducted in all follow-up visits during the 48 days. All individuals will be classified in: a) Early treatment failure b) Late Clinical Failure, Late Parasitological Failure and adequate clinical and parasitological response. As the parasitological cure is the endpoint of treatment of malaria, all individuals classified as treatment failure should be treated with the alternative scheme (quinine + doxycycline). | 42 days | No |
Secondary | Description of adverse events | Any sign or symptom that is not present in the clinical evaluation of D0 and focusing on subsequent evaluations, will be defined as adverse effects of the treatment. For this, a list of signs and symptoms should be questioned participants at all follow-up visits and adverse effects identified will be properly recorded. Depending on the intensity, these adverse effects should be treated according to medical advice. The subject of the study with more severe adverse effects will be referenced to a secondary or tertiary health care for the Juruá Hospital. | 42 days | Yes |
