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在苏丹东部新哈勒法疟疾传播季节性中的作用。利用1986 - 2002年期间的月度气候变量、作物灌溉可用月水量以及疟疾月血片阳性率进行了时间序列分析。全年每月均有疟疾病例报告，平均为13.0/100人/月（95%可信区间：11.9 - 14.2），且在秋季和冬季呈现双峰年模式。降雨是该疾病传播中的重要气候变量，而强降雨被发现会引发疫情。温度、相对湿度和灌溉用水不是显著因素。
