【摘要】：目的了解贵州省B型流感病毒的流行特征和规律,为其预防与控制提供依据。方法采用描述性方法对贵州省2013年4月1日—2016年3月31日B型流感病毒RT-PCR检测结果进行统计。结果贵州省2013—2016年3个监测年度B型流感病毒RT-PCR检测阳性1 904份,其中By系1 215份、Bv系642份,2013年4月—2014年3月、2014年4月—2015年3月2个监测年度B型流感的优势流行株都是By系,而2015年4月—2016年3月是Bv和By系共同流行,流行季节主要在冬春季;B型流感病毒男性检出所占比率较高,占56.83%;15岁以下低年龄组人群B型流感病毒检出数最高(70.80%),而Bv系在0~岁年龄组最高(42.37%),By系在5~岁年龄组最高(35.56%);混合感染病原组合构成主要以By+Bv为主,占67.65%,与B型有关的混合感染数占95.59%。结论贵州省B型流感病毒存在By和Bv两种系别的流行,流行季节为冬春季,男性感染病例多于女性,发病以15岁以下人群为主,加强低年龄群体流感疫苗的接种和监测具有重要意义。
[Abstract]:Objective to investigate the epidemic characteristics and regularity of influenza B virus in Guizhou province and to provide evidence for its prevention and control. Methods the RT-PCR detection results of influenza B virus from April 1, 2013 to March 31, 2016 in Guizhou Province were analyzed by descriptive method. Results there were 1 904 RT-PCR positive samples of influenza B virus in three surveillance years in Guizhou Province from 2013 to 2016. Of these, 1 215 strains of By were identified, 642 were from April 2013 to March 2014, 2 dominant strains of influenza B from April 2014 to March 2015 were By strains, and from April 2015 to March 2016, Bv and by strains were both prevalent. The prevalence of influenza B virus in winter and spring was relatively high in males. The highest detectable number of influenza B virus was 70.80 in the low age group of 56.83 years old, while the highest in the 0 ~ year old group was 42.37%, and the highest in the age group of 5 ~ years old was 35.56%, and the composition of the mixed infection pathogen was mainly By Bv. The number of mixed infection related to type B was 95.59. Conclusion there are two strains of influenza B virus in Guizhou Province, namely, by and B v. The epidemic season is winter and spring. The number of male cases of influenza B infection is more than that of female, and the incidence of influenza B virus is mainly in the population under 15 years of age. It is of great significance to strengthen the vaccination and surveillance of influenza vaccine in low age groups.
