1.九江市城乡24年以来,共发生流行性出血热1,163例,死亡81例,平均病死率为6.96％。24年内曾有两次较大的流行,第一次在1973年(4.1/10万),第二次在1982～1984年(3.6～4.93/10万)。 2.全市13个县(区)中,有1个高发县(37.1/10呖),4个中发县(5.63～21.3/10万),7个低发县(0.15～4.28/10万),只有1个县未出现过病例。 3.黑线姬鼠为九江市出血热主要传染源。其HFRS抗原阳性率高发区>中发区>低发区>未发病区。未发现过病例的地区无阳性鼠检出。 4.在血清抗体检测中,以病后1～5年阳性率为高,6～10年次之,11年以上较低。并且病后持续13年的血清抗体仍保持一定的水平。
1. In urban and rural areas of Jiujiang City, there were 1,163 cases of epidemic hemorrhagic fever and 81 deaths in a 24-year period with an average case-fatality rate of 6.96%. There were two major epidemics in 24 years, the first in 1973 (4.1 / 100,000) and the second in 1982-1984 (3.6 to 4.93 / 100,000). 2. Among the 13 counties (districts) in the city, there are 1 high-incidence county (37.1 / 10 呖), 4 Zhongfa County (5.63-21.3 / 100,000) and 7 low-counties (0.15-4.80 / 100,000) Only one county did not have any cases. 3 black line Apodemus Jiujiang hemorrhagic fever as the main source of infection. The positive rate of HFRS antigen was> incidence area> low incidence area> non-incidence area. No cases were found in the absence of positive mice detected. 4. Serum antibody test to 1 to 5 years after the disease positive rate was high, 6 to 10 years followed by 11 years or less. And after the disease for 13 years of serum antibodies still maintain a certain level.
