Randomized epidemiological studies conducted inside the Rift Valley fever epidemic area permitted an estimate of the different epidemiological rates. For the town of Rosso, the total number of infected persons was estimated at 9,320, the total number of symptomatic diseases at 1,013 and the number of deaths at 47. The minimal number of deaths for the area which had access to the hospital was 232. The immunity rate in the town was 34.89% after the epidemic. The ELISA test was used to test human and animal IgG and IgM antibodies. Human samples were collected using the "confetti" technique. After the epizootic the incidence was 36.9% and the immunity was 70.06% for animals sampled in the town.
在裂谷热疫区进行的随机流行病学研究使得对不同的流行病学发病率进行估算成为可能。对于罗索镇，估计的感染总人数为9320人，有症状疾病的总人数为1013人，死亡人数为47人。该地区可前往医院就诊的人群中死亡人数最少为232人。疫情过后，该镇的免疫率为34.89%。采用酶联免疫吸附测定（ELISA）试验检测人和动物的IgG和IgM抗体。使用“五彩纸屑”技术采集人类样本。动物疫情过后，在该镇采集样本的动物发病率为36.9%，免疫率为70.06%。
