Hospital records (1990-1997) of a tea company in the Kericho district, western Kenya, showed malaria epidemics almost annually from May to July, with an annual attack rate of 50%, 857 hospitalizations per 100,000 per year, and 42 deaths per 100,000 per year; 32% of deaths in hospitalized patients were caused by malaria. A questionnaire survey (June 1997) of 244 patients hospitalized for malaria showed that only 8% had traveled to an area with known malaria transmission 30 days before diagnosis. The increasing malaria incidence may be due to drug resistance.
肯尼亚西部凯里乔区一家茶叶公司的医院记录（1990 - 1997年）显示，几乎每年5月至7月都会发生疟疾流行，年发病率为50%，每年每10万人中有857人住院，每年每10万人中有42人死亡；住院患者中32%的死亡由疟疾所致。1997年6月对244名因疟疾住院的患者进行的问卷调查显示，只有8%的患者在诊断前30天前往过已知有疟疾传播的地区。疟疾发病率上升可能是由于耐药性。
