The study investigated the role of climatic variables and irrigated agricultural on the seasonality of malaria transmission in New Halfa, eastern Sudan. A time-series analysis was performed using monthly climatic variables, monthly water available for irrigation of crops and monthly slide positive rate of malaria during the period 1986-2002. Cases of malaria were reported every month of the year with a mean of 13.0/100 persons/month (95% CI: 11.9-14.2), and bimodal annual pattern in autumn and winter seasons. Rainfall was the significant climatic variable in the transmission of the disease, whereas heavy rainfall was found to initiate epidemics. Temperature, relative humidity and irrigation water were not significant factors.

该研究调查了气候变量和灌溉农业对苏丹东部新哈尔法疟疾传播季节性的作用。在1986-2002年期间,使用每月气候变量,可用于灌溉农作物的每月水和疟疾的每月滑动阳性率进行了时间序列分析。每年每月报告疟疾病例,平均13.0/100人/月 (95% CI: 11.9-14.2),秋季和冬季的双峰年度模式。降雨是疾病传播的重要气候变量,而发现大雨引发了流行病。温度,相对湿度和灌溉水不是显着因素。
