目的了解衡阳县不同人群乙型病毒性肝炎(简称乙肝)抗体免疫水平。方法 2009年6-8月,采用系统随机抽样的方法,在全县各预防接种门诊辖区人群中对1周岁及以上人群进行乙肝血清流行病学调查。用荧光免疫技术(TRFIA)检测乙肝免疫抗体(抗-HBs)。结果共完成血清学调查284人,均为县籍户口(汉族),抗-HBs阳性人数214人,阳性率为75.35%。结论衡阳县人群乙肝免疫水平较高,充分体现了该县从1986年开始接种血源乙肝疫苗以来所取得的效果。为降低乙肝的发病率,今后还应进一步加强乙肝防控工作,继续提高人群乙肝疫苗接种率和人群抗-HBs阳性率。
Objective To understand the immune status of hepatitis B virus (HBV) in different population of Hengyang County. Methods From June to August in 2009, a systematic random sampling method was used to survey the seroprevalence of hepatitis B in people over 1 year of age and above among the population of all vaccination clinics in the county. Hepatitis B immune antibodies (anti-HBs) were detected by fluorescent immunofluorescence (TRFIA). Results A total of 284 serological surveys were completed, all of which were county-owned (Han nationality), 214 were positive for anti-HBs, and the positive rate was 75.35%. Conclusion The level of hepatitis B immunization in Hengyang County is high, which fully shows the effect of Hepatitis B vaccine since it was inoculated in Hexi County in 1986. In order to reduce the incidence of hepatitis B, we should further strengthen the prevention and control of hepatitis B in the future and continue to raise the population hepatitis B vaccination rate and population anti-HBs positive rate.
