2016-2020年福建省布鲁氏菌病流行特征及防控策略探讨

Epidemiological characteristics and control strategy of human brucellosis in Fujian, 2016−2020

  • 摘要:
      目的  探讨福建省人感染布鲁氏菌病流行特征,为制定预防控制策略提供科学依据。
      方法  收集中国疾病预防控制信息系统中2016—2020年福建省人感染布鲁氏菌病报告数据和血清学及病原学监测数据,运用描述性流行病学方法对其进行流行特征和疫情趋势分析。
      结果  2016—2020年福建省共报告布鲁氏菌病515例,年均发病率0.26/10万,发病呈逐年增长趋势(趋势χ2=12.88,P<0.05);疫情波及福建省87.50%的县(区),呈高度散发态势,南平市和龙岩市发病率居前,分别为0.64/10万和0.52/10万,发病区(县)数呈增加趋势(趋势χ2=9.29,P<0.05),由2016年的28个增加到2020年的49个;发病高峰为4—8月;40~64岁发病数占62.33%,60~64岁组发病率最高(0.69/10万);男女性发病率比为1.89∶1(χ2=44.77,P<0.05),农牧民占42.33%。 重点职业人群监测工作中,血清学检测4 934人,阳性84例,阳性率为1.70%。 38株布鲁氏菌分离株经鉴定为2个种(羊种和猪种)和2个生物型(羊3型和猪3型),其中羊种布鲁氏菌占97.37%。
      结论  福建省布鲁氏菌病流行强度逐年增高,建议相关部门加强传染源的管控、对疫情高发地区的重点人群采取必要防控措施,提高布鲁氏菌病监测能力,控制其发生与流行。

     

    Abstract:
      Objective  To explore the epidemiological characteristics of human brucellosis in Fujian province during 2016−2020, and provide scientific evidence for the development of effective brucellosis control and prevention strategy.
      Methods  The incidence data and serological and etiological surveillance results of human brucellosis in Fujian from 2016 to 2020 were collected from China Information System for Disease Control and Prevention for a descriptive epidemiological analysis.
      Results  A total of 515 human brucellosis cases were reported in Fujian during this period. The annual incidence was 0.26/100 000 and the incidence of human brucellosis increased year by year (χ2=12.88, P<0.05). The cases were distributed sporadically in 77 counties (87.50%) in the province. The incidence was 0.64/100 000 in Nanping and 0.52/100 000 in Longyan, which were higher than in other areas. The number of affected counties (district) increased from 28 in 2016 to 49 in 2020, showing a significant increase (χ2=9.29, P<0.05). The incidence peak of human brucellosis occurred during April-August. In the reported cases, 321 (62.33%) were aged 40–64 years; the highest incidence rate was at age group 60–64 years old (0.69/100 000). The male to female ratio of the cases was 1.89∶1 (χ2=44.77, P<0.05). The cases in farmers and herdsmen accounted for 42.33% (218 cases). In the surveillance in key populations with occupational exposure, 84 persons were serological positive (1.70%, 84/4 934). With classical biotyping and molecular biological methods,two species (B. melitensis and B.suis) and two biovars (B. melitensis biovar 3, n=37; and B.suis biovar 3, n=1) were identified in the 38 Brucella isolates, and B.melitensis was the major pathogen causing human brucellosis in Fujian (97.37%).
      Conclusion  Our study indicated that the incidence intensity of human brucellosis in Fujian increased yearly. It is necessary to strengthen brucellosis surveillance and infection source management and control, and take corresponding measures in high-risk population for the better prevention and control of human brucellosis.
