目的为预测流感的大流行,及时制定防制措施,2001年黑龙江省全面开展了流感监测工作。方法全省共7家医院为国家流感监测哨点医院,监测医院每周采集内科、儿科门诊就诊的流感样病人咽拭子样本,并在4~8℃下24 h内送黑龙江省国家流感网络实验室做病毒分离。结果2006年10月~2007年3月从642份流感样病人咽拭子中分离出流感病毒107株,对87株毒株进行分型鉴定其中H1N1亚型67株(77%),H3N2亚型20株(23%),未发现B型毒株。结论黑龙江省流感疫情较平静,多以散发病例存在,人群中同时有H1亚型和H3亚型流感病毒流行,优势毒株为H1亚型。建议接种疫苗以减少流感感染。
The purpose is to predict the pandemic of influenza and make prevention measures in a timely manner. In 2001, Heilongjiang Province conducted a comprehensive influenza surveillance work. Methods A total of 7 hospitals in the province were selected as national influenza surveillance sentinel hospitals. Surveillance hospitals collected weekly samples of throat swabs from internal medicine and pediatric outpatients for flu-like illness and sent them to Heilongjiang National Influenza Network within 24 h at 4 ~ 8 ℃. Laboratory virus isolation. Results From October 2006 to March 2007, 107 influenza viruses were isolated from 642 throat swabs of influenza-like patients, and 87 strains were identified, including 67 H1N1 subtypes (77%), H3N2 subtype 20 strains (23%), no type B strains were found. Conclusion The influenza outbreaks in Heilongjiang Province were relatively calm and sporadic cases were more common. In the population, H1 and H3 subtype influenza viruses were endemic, and the predominant strains were H1 subtype. Vaccination is recommended to reduce flu infections.
