 Study Intervention: Pilot period: After enrollment, households will participate in a one month pilot period to test the household pictorial diaries. At the end of the pilot period, households will be randomized to participation in the home-based management of fever HBMF arm or standard care arm for the remainder of the study 12 months. HBMF arm: Households randomized to the HBMF group will be provided with pre-packaged coartemether to keep at home. Primary caregivers will be instructed to treat children participating in the study empirically with coartemether at home when the child develops fever. Study personnel will distribute drugs and educate the caregivers about administration of drugs, recognition of danger signs of fevermalaria, and when to seek additional care. Standard care: Households randomized to the standard care arm will be asked to continue their current behaviour and to manage fever in their children as they would normally.
