家鼠型流行性出血热疫源地有效控制指标和方法的研究

Studies on Indices ahd Methods for Effective Control of the Focus of Infection of House-rat Type of Epidemic Hemorrhagic Fever.

本文通过四年调查,认为以锦西市为中心的锦州地区EHF疫源地,确已得到有效控制。家鼠型EHF疫源地五项指标中,褐家鼠密度和EHF抗原阳性率可代表鼠传播EHF的能力,是主要的监测指标;发病率表示鼠间EHF对人群作用的后果,反应了流行强度,是监测的直接指标;其余两项仅为间接指标。本文对控制家鼠型EHF疫源地五项具体指标提出了建议。全民连续性以药物为主的灭鼠和疫区强制灭鼠,是控制EHF疫源地有效、可靠的方法。

Through 4-year investigations, it is believed that, the focus of infection of epidemic hemorrhagic,fever (EHF) in Jinxi Municipality which is located in the, center of Jinzhou Area has been effectively controlled. Among the five indices for house-rat type of EHF, the density of Rattus norvegicus and- he EHF antigen positive rate which represented the ability of rat to transmit EHF played important roles serving as the main monitoring indices. The morbidity, which represcnted the consequence of the effect of EHF among rats on humans reflected the ihtensity of epidemic serving as the direct indent for surveillance. While the rest two indices served only as indirect indices. Frequent extermination of rats with poison by the whole people and forced extermination of rats in eptdemic areas were the effective and reliable methods for control of the focus of infection of EHF.
