| Abstract: |
| 对采自山西农村居民的521份血清，同时检测HBsAg（RPHA、SPRIA）、抗-HBs（PHA、SPRIA）及抗-HBc（IAHA）。测定结果具有一项以上乙肝感染标志的血清有201份，乙肝病毒的总感染率为38.58%。在521份血清中，HBsAg、抗-HBs及抗-HBc的阳性率分别为8.45%、23.22%及18.81%。SPRIA的检出率比血凝法高2.5%（HBsAg）和18.81%（抗-HBs）。有39份（7.48%）血清为单独抗-HBc一项阳性。乙肝的总感染率男女间未发现有显著差异，各年龄组间有一定差异，<5岁者最低，5岁后急剧升高，至40~50岁组达高峰，50岁以后又有所下降。 |

| A total number of 521 serum samples collected from the villagers in Shanxi province were tested for HBsAg (RPHA and SPRIA), anti-HBs (PHA and SPRIA) and anti-HBc (IAHA). The results of detection showed that 201 serum samples having one or more markers of HBV infection and an overall HBV prevalence rate of 38.58%. Of the 521 serum samples positive rates for HBsAg, anti-HBs and anti-HBc were found to be 8.45%, 23.22% and 18.81% respectively. The detection rates of SPRIA were 2.5% (HBsAg) and 18.81% (anti-HBs) higher than that using hemagglutination method. Among the samples tested, 39 (7.48%) were anti-HBc positive. Although there was no significant difference of HBV overall prevalence rates between males and females, but some differences were found in various age groups. The prevalence rate was the lowest under 5 years of age hut increased rapidly. It reached the peak in the age group of 40-50 and decreased at the age above 50. |
