Our research team will register the children as "cured" after receiving the short text message or the diary. If needed, reminders to complete the study documents will be sent by post after 14 days. If there is no response, the research team will contact the parents by telephone (at least 3 attempts). In the last case, the clinician, who initially recorded the case, will be contacted to verify if the child completely healed or was referred to the hospital. In case of referral and/or hospitalisation, the primary care and hospital clinicians will be contacted to reconstruct the illness episode (reason for referral/hospitalisation, diagnosis, time to cure).
