目的:观察某舰艇部队流感暴发特征及控制效果。方法:对A、B两舰病人采用鸡胚双腔法行咽拭子病毒分离,用血细胞凝集抑制试验行病毒鉴定。对先发生流感的A舰病人行隔离治疗,对密切接触者行医学观察;对后发生流感的B舰采取相应干预措施。结果:A舰发病率21.0%,与之相邻的B舰2.7%。两组比较,差异非常显著(P<0.01)。A舰≤1年兵龄组的发病率与≤2年、≤3年及>3年兵龄组相比,差异非常显著(P<0.01)。结论:及时发现和报告疫情、严格隔离、加强健康教育和接种流感疫苗是控制流感暴发的重要措施。
Objective: To observe the characteristics and control effects of influenza in a naval force. Methods: A, B two-vessel chickens were enrolled in this study. The throat swab virus was isolated by double chamber method and identified by hemagglutination inhibition test. On the first occurrence of influenza A-line patients isolated treatment, close contact with the medical observation; after the influenza B ship take appropriate interventions. Results: A ship incidence of 21.0%, with the adjacent B ship 2.7%. The differences between the two groups were significant (P <0.01). The incidence of A-wars ≤1-year age group was significantly higher than that of younger than 2-year, ≤3-year and> 3-year age groups (P <0.01). Conclusion: Timely detection and reporting of outbreaks, strict isolation, strengthening of health education and vaccination against influenza are important measures to control the outbreak of influenza.
