目的为了解宿主动物密度、构成和感染情况,为防治出血热工作提供科学依据。方法夹夜法。结果 2008-2010年共捕鼠700只,共4科7属9种,分布于居民庭院、库房及野外农田、草地、灌木丛等。优势种为黑线姬鼠、褐家鼠,平均鼠密度为3.83%,带毒率为9%。结论凤城地区的流行性出血热疫情流行高峰和春秋季节鼠密度较高密切相关,为此控制出血热的发生和流行关键在于春秋季前开展村内外较大规模的灭鼠防鼠工作和出血热疫苗接种工作。减少劳作和家庭环境中与鼠的接触及提高免疫力,是控制和降低出血热发病的有效措施。
Objective To understand the density, composition and infection of host animals and provide a scientific basis for the prevention and treatment of haemorrhagic fever. Method of nocturnal method. Results A total of 700 trapping mice were found in 2008-2010, belonging to 9 families, 7 genera and 9 species, distributed in residential courtyards, warehouse and field farmland, grassland and shrubs. The dominant species were Apodemus agrarius and Rattus norvegicus, the average rat density was 3.83% and the infection rate was 9%. Conclusions The peak epidemic peak of epidemic hemorrhagic fever in Fengcheng area is closely related to the high density of rats in spring and autumn. Therefore, the key to control the occurrence and prevalence of hemorrhagic fever is to conduct large-scale anti-rat and rodent prevention work and bleeding within and outside the village before and after the Spring and Autumn Period Hot vaccination work. Reducing exposure to rats and enhancing immunity in labor and home settings is an effective measure to control and reduce the incidence of haemorrhagic fever.
