湖北省1991～1995年肾综合征出血热监测分析

Analysis on Hemorrhagic Fever with Renal Syndrome (HFRS) Surveillance in Hubei Province 1991-1995

通过对本省肾综合征出血热（ＨＦＲＳ）１９９１～１９９５年监测和疫情资料的总结，发现该病在本省的宿主动物，野外以黑线姬鼠为优势鼠种，且带病毒率最高，室内以褐家鼠为优势鼠种，黄胸鼠带病毒率最高；近几年各小区秋冬季发病高峰前的平均鼠密度、鼠带毒率、鼠感染率都低于春季；全省健康人群ＨＦＲＳ隐性感染率与全国混合型疫区相近，但各地理小区的隐性感染率有显著差别；鄂西南山地小区（Ⅱ）健康人群隐性感染率明显高于其它小区；全省ＨＦＲＳ的季节分布仍为双峰型，疫区类型仍为姬鼠型为主的混合型疫区，各小区的疫区类型有所不同，且在不断演变；与以往相比，秋冬峰病例在全年病例中所占的比例有所下降，这是本省疫情相对稳定的一个因素。

The data indicated that the major sources of infection of HFRS were Apodemus agrarius in field;Rattus norvegicus and R.flavipectus in door in Hubei Province.The average densities,virus carrier rate and infectious rate of rodents in fall and winter were less than that in spring.There was significant difference of human latent infectious rates among various geographical areas.The human latent infectious rate in south west mountain area was more higher than that in the others.The season contribution of HFRS was double peak pattern in whole province.The infectious focux was mixed type with the main type of Apodemus agrarius.The case number of fall witer peak was decreased when compared with the past years.This was one of the factors which made the epidemic status more stable.
