目的分析珠海地区出入境人员乙肝病毒感染情况,以便有针对性地开展传染病监测工作。方法从性别、年龄、职业分布等方面对2004年1月～2006年9月珠海出入境人员乙肝病毒血清学检测结果进行分析。结果从38 268名出入境人员中检出3 670例HBsAg携带者,感染率为9.59%。其中男性感染率为11.05%(2915/26378),女性6.35%(755/11890),男性感染率明显高于女性。不同年龄组间HBV感染率差异也统计学意义。31～40岁和41～50岁年龄组感染率较高。从职业分布情况来看,交通员工HBV感染率为10.66%(占总感染人数的73.02%),劳务人员感染率为8.16%(占总感染人数的24.66),两者共占总感染人数的97.68%。结论应重点对交通员工和劳务人员的HBV检测,积极推广乙肝疫苗的接种,加强HBV防护知识的宣传。
Objective To analyze the status of hepatitis B virus infection in entry and exit personnel in Zhuhai so as to carry out the surveillance of infectious diseases in a targeted manner. Methods The serological test results of hepatitis B virus in Zhuhai immigrants from January 2004 to September 2006 were analyzed from the aspects of sex, age and occupational distribution. Results A total of 3 670 HBsAg carriers were detected among 38 268 immigrants arriving and departing. The infection rate was 9.59%. Including male infection rate was 11.05% (2915/26378), female 6.35% (755/11890), the male infection rate was significantly higher than the female. HBV infection rates among different age groups also have statistical significance. The infection rates were higher in 31-40 years old and 41-50 years old group. In terms of occupational distribution, the rate of HBV infection among traffic workers was 10.66% (accounting for 73.02% of the total number of infected persons), the infection rate of laborers was 8.16% (accounting for 24.66 of the total number of infected persons), and both accounted for 97.68 of the total number of infected persons %. Conclusion It is necessary to focus on the detection of HBV by traffic staff and service personnel, actively promote the vaccination of hepatitis B vaccine and strengthen the publicity of HBV protection knowledge.
