【摘要】 本文分析了1980年来肾综合征出血热流行趋势。90年代与80年代相比该病发病率经趋势性检验，趋势性系数r＝－0．59，下降趋势非常显著。发病季节冬峰构成下降14．6％，春峰上升7．8％；年龄构成40岁以上上升9．2％；性别构成女性上升4．2％。鼠密度、鼠带毒率及带毒指数均呈下降趋势。家鼠型主要传播媒介黑线姬鼠构成比下降19．4％。全县数次大规模灭鼠，灭鼠率达80％以上，对一个高发乡镇约5000人接种HFRS疫苗，3年保护率100％。今后HFRS防制在抓好灭鼠防鼠这一主要措施的同时，应把普及HFRS疫苗接种作为主导措施来抓。更多还原

【Abstract】 The prevalent tendency of hemorrhagic fever with renal syndrome since 1980 was anslysed. The incidence rates in 1990’s and 1980’s were compared. Tendency test showed that the coefficient of tendency (r) was—0. 59, the tendency of decline was significant. The incidence ratio in winter in 1990’s declined by 14. 6% in comparison with that in 1980’s, and that in sping rose by 7. 8%. The incidence ratio in popular whose age was more than 40 rose by 9. 2%, and that in women rose by 4. 2%. The rats density, rate of carrying virus in rats and index of carrying virus in rats showed the tendency of decline. The ratio of the main host of HFRS type Ⅱ, R. norvegicus rose by 56. 4%, and that of the main host of HFRS type I, A. agrarius declined by 19. 4%.Several times of killing rats were carried out in large area, the rate of killing rats was more than 80%. In a town of high incidence rate, about 5000 persons were immuned with HFRS vaccine, the protective rate was 100% during three years. It suggested that,in order to prevent HFRS, killing and guarding against rats should be carried on, meanwhile vaccine inoculating must be of importance.更多还原
