Epidemiological investigation on antibody level of HFRS in Gansu Provence.

于1994年10月～1995年10月对不同流行强度疫区的健康人群进行HFRS抗体检测(共3901份),平均阳性率为3.41％。不同流行强度疫区的隐性感染率差异有显著性(P<0.01)。隐性感染主要发生在成年组,10岁以下组最低(1.07％),50～59岁组最高(5.62％)。职业隐性感染率农民最高(4.51％),依次为医务工作者(3.28％)、工人(2.88％)、散居儿童(2.35％)、干部(2.04％)和学生(1.96％)。共检测注射过HFRS疫苗的血清240份,总阳性率为77.92％。对HFRS的流行情况及其预防进行了讨论。

Antibody level of HFRS in health crowed from different epidemic intensity's focus is investigated average positive rate is 3. 41%. The result shows there esists obvious difference in latent infection rate among different epidemic intensity's focus (P < 0.01). Latent infection is mainly in adult group. Under 10 - year group is the lowest (1. 07%) ,50- 59 - year group is the highest (5. 62%). In occupation, the farmer is the highest (4. 51%), and medical worker (3. 28%), worker (2. 88%), children (2.35%), cadre (2. 04%) and student (1. 96%) in turn. 240 serum specimins from crowed injected HFRS vaccine were detected total positive rate is 77. 92%. The epidemic trend and prevention of HFRS were discussed.
