目的评价监测效果评估全省急性乙型病毒性肝炎(乙肝)报告数据,为进一步开展全省急性乙型病毒性肝炎监测提供依据。方法在城乡疾病监测县开展急性乙型病毒性肝炎监测,对所有未能明确诊断为慢性乙肝的病例开展现场调查和实验室核查以明确最终分类,并采用描述流行病学方法结合乙肝疫苗常规免疫接种资料分析监测前后乙肝法定传染病报告数据。结果 2010-2015年开展监测前后,全省以及监测县乙肝疫苗全程接种率持续保持在较高水平,监测县报告乙肝病例中急性病例占比从9.80%降至4.14%,下降了57.86%,农村监测县降幅远远高于城市监测县,全省从4.80%增至6.43%,增加了33.96%;开展监测前,监测县急性乙肝报告发病率高于全省,开展监测后低于全省平均水平。结论通过加强病例监测工作,疾病监测县乙肝分类构成发生改变,急性乙肝报告发病率由高于全省平均水平降为低于全省平均水平,推测全省急性乙肝报告发病率可能高于实际水平,有必要进一步加强全省范围的乙肝病例监测。 Objective To evaluate the monitoring effect of the province’s acute hepatitis B (hepatitis B) data to provide evidence for further monitoring of acute hepatitis B in the province. Methods Acute hepatitis B surveillance was carried out in urban and rural disease surveillance counties. All the cases that failed to be diagnosed as chronic hepatitis B were investigated by field survey and laboratory verification to confirm the final classification. Epidemiological methods combined with conventional immunization of hepatitis B vaccine Inoculation data analysis before and after monitoring of statutory hepatitis B reported data. Results Before and after the monitoring was carried out from 2010 to 2015, the whole vaccination rate of hepatitis B vaccine in the whole province and monitoring counties maintained a relatively high level. The proportion of acute cases in hepatitis B cases in monitoring counties dropped from 9.80% to 4.14%, down by 57.86% The rate of decrease in monitoring counties was much higher than that in urban counties, the province increased from 4.80% to 6.43%, an increase of 33.96%; before the monitoring, the incidence of acute hepatitis B in monitoring counties was higher than that in the province, Level. Conclusion By strengthening case surveillance, the composition of hepatitis B in the disease monitoring counties has changed. The incidence of acute hepatitis B is reported to be lower than the provincial average, which suggests that the incidence of acute hepatitis B in the province may be higher than the actual level , There is a need to further strengthen the province-wide surveillance of hepatitis B cases.
