【摘要】 [目的]了解包头市人群对甲3型、甲1型流感病毒和禽流感病毒H9、H5的抗体,探讨甲3型、甲1型流感流行的趋势和禽流感病毒H9抗体存在情况。从而了解包头市流行性感冒(流感)流行规律和毒株的变异动态,为及早发现和控制疫情提供科学依据。[方法]应用常规血凝抑制试验微量半加敏法对包头市不同年龄组人群进行甲型流感抗体血清学监测。[结果]A1/上海/7/1999(H1N1)毒株的抗体阳性率为38.2%;A3/江西/424/2004(H3N2)毒株的抗体阳性率为79.1%;禽源H9N2毒株的抗体阳性率为36%。[结论]A3/江西/424/2004(H3N2)毒株已不可能在包头地区再度引起流行;A1/上海/7/1999(H1N1)毒株今后在人群中,特别在0～15岁年龄组中可能存在散在性发生或局限性小暴发;本市人群曾受到禽流感H9病毒的感染,不能排除由本市禽类中的H9病毒感染及人的可能。禽流感病毒在本市禽类中的感染状况及对人的影响需进一步研究。更多还原

【Abstract】 [Objective] To understand the antibody of influenza A3 and A1 among people in Baotou and the avian influenza H9 and H5 viruses, and explore the trend of influenza A3 and A1 and status of avian influenza H9, so as to understand the epidemic trend and influenza viral variation of influenza.Ultimately, we could provide scientific basis for early detection and control influenza.[Methods] The titers of antibodies to influenza A(H1, H3, H9) viruses were detected by hemagglutina-tion-inhibition test.[Results] The positive rate of A1/ Shanghai / 7 / 1999(H1N1) was 38.2%, and the positive rate of A3/ Jiangxi / 424 / 2004(H3N2) was 79.1%.The positive rate of H9N2 antibody was 36%.[Conclusion] It’s impossible that A3/ Jiangxi / 424 / 2004(H3N2) virus could arise an epidemic in Baotou.It is possible that A1 / Shanghai / 7 / 1999(H1N1) virus could arise limited epidemic and scattered cases, especially for 0-15 age group in Baotou.People were infected by avian influenza H9 virus in Baotou, so the possibility of the influenza H9 virustransmisson from local aves to people could not be excluded.Therefore, the situation of local aves infected by avian influenza viruses and their influence to people should be further studied.更多还原
