| Abstract: |
| 1988~1990年,对野鼠型和家鼠型肾综合征出血热疫区7145人进行了隐性感染定群研究。1989年和1990年抗体阳转率,野鼠型疫区以20~49岁、农民最高,男女之比为2.1~2.2:1;家鼠型疫区各年龄组无显著性差别,家庭妇女最高,男女之比为0.9:1。显性感染与隐性感染之比,野鼠型疫区为1:22.6,家鼠型疫区为1:42,表明HFRS是一种以隐性感染为主的疾病,在人群中主要呈潜在流行。 |

| Between 1988 and 1990, the positive seroconversion rates of HFRS were tested with a random sample of 7145 persons in Apodemus-type endemic area and Rattus-type endemic area (type A; type R) in Shandong Province. The results showed that:(1) the highest positive seroconversion rate was in the group of peasants of 20 to 49 years of age in the area of type A; (2) in the area of type R, there was no statistically significant difference in positive seroconversion rates of age, and housewives had the highest rate. The male/female ratio was 2.1-2.2:1 and 0.9:1, respectively in the two types of endemic area. The ratio of apparent infection to inapparent infection was 1:22.6 and 1:42, respectively in the two types of area. It is concluded that inapparent infection is dominant in HFRS infection and there are probably many potential inapparent infections among the population. |
