摘要
岷县是甘肃省流行性出血热（EHF）的高发病县。1992年始发病流行至1995年疫情涉及全县22个乡镇的181个村，累计病例1160人，病死19人，年最高发病率199．44／10万，病死率1．64％。1995年发病率降至19．02／10万，发病乡镇减少到14个，表明疫情已得到基本控制。经调查证实有六种鼠类携带EHF病毒，总带毒率2．95％，其中黑线姬鼠为4．95％，且广泛分布于2000～3000米之间的各种生境，最高密度为8．15％，是室内外的优势种群，也是该地EHF的主要宿主动物。缓慢细蚤和厩真厉螨为主要可疑媒介。直接接触染疫动物及污染物是感染发病的主要原因。
There was much more prevalence of epidemic hemorrhagic fever (EHF) in Minxian, Gansu.From the first of the disease onset in l992 to l995, l8l villags out of 22 countrysides/towns of the whole county were involved with 1160 cases totally and 19 patients died of the disease. The highest incidence and fatalityof the year was 199. 44/100 000 and l. 64 % respectively- ln l995, there had been a decrease in the incidence to 19. 02/100 000 and involved countrysides/towns to l4. It suggested that the epidemic were controlled basically. Six species of rodents were determined to be carriers of EHF virus with totlly virus-carrying rate of 2. 95%. Apodemus agrarius, that 4- 95% was virus carriers, distributed widely in various kinds of habitat at altitude from 2 000-3 000m. With 8. l5% the highest density, they occupied a position of dominant population both in house and field, and the main hosts of EHF in this area. Leptopsylla sagnis and Laelaps echidninus were mainly suspicious vectors- The infective attack of EHF should be due to contagion of infected animals directly and pollutant.
