This report documents the effects of malaria epidemic and how it was controlled in one highland district of Kenya. The effects of the epidemic are presented in terms of mortality, morbidity and school absenteeism; information is from routine and verbal reports. Treatment with chloroquine, amodiaquine and sulphonamide pyrimethamine combinations, limited vector control, and health education were used to control the epidemic. Hospital mortality per month increased by 8.6 times during the epidemic while morbidity went up by 3.7 times. Of the 103 deaths attributed to malaria, 64 (62.1%) occurred in hospital and 39 (37.9%) at home. Most of the home deaths (92.3%), occurred in areas that border the malaria endemic Lake Victoria Basin. The rate of pupil absenteeism ranged from 17.6% to 54.4% in primary schools. The policy implications of the report are discussed.
