1989年7月于我县选取流行性出血热(EHF)发病率及鼠密度等条件基本相同的60个自然村,设其中的30个村为观察组,其余30个村为对照组,在观察组用鼠钠盐进行疫点灭鼠,并于1年后观察两组EHF 的发病情况.灭鼠方法统一用5～7/万敌鼠钠盐,以小麦、玉米为诱饵,每间房3～5堆,每堆50g,连放3天,于1989年7、8月分两批进行疫点灭鼠,两次共用毒饵5861kg。EHF 诊断标准参照全国流行性出血热诊断标准和全国出血热防治《试行》方案中规定的早期诊断标准.结果灭鼠前后鼠密度及EHF 发病情况(附表)
In July 1989, 60 natural villages with similar incidences of epidemic hemorrhagic fever (EHF) and mouse densities were selected in our county. 30 villages were selected as the observation group and the remaining 30 villages as the control group. In the observation group Rat sodium salt was used for rodent control, and the incidence of EHF in both groups was observed after 1 year. The rodent control method consisted of using 5 to 7/50000 natrium sodium salt, using wheat and corn as bait, 3 to 5 piles in each house, Each pile of 50g, and even put three days, in July and August 1989 two batches of epidemic rodent control, 5861kg common use of bait twice. EHF diagnostic criteria with reference to the national diagnostic criteria for epidemic hemorrhagic fever and national hemorrhagic fever prevention and treatment of “pilot” program in the early diagnosis criteria.Results rodent rat rat density and EHF incidence (Schedule)
