目的了解安徽省流感病毒活动特征,为流感科学防控提供依据。方法对2010~2015年度安徽省流感监测哨点医院流感样病例标本病原学检测结果进行统计分析。结果 2010~2015年度安徽省流感样病例阳性率依次为9.44%、12.83%、8.40%、14.95%和13.28%;总体呈现季H3型、新甲H1型和B型交替或共同流行的态势;每年冬春季高峰必然出现,多出现在1~3月;而夏季高峰隔年出现,多出现在7~9月;A型流感病毒在夏季和冬春季高发,而B型流感则只在冬春季高发。结论每年1~3月和7~9月是安徽省流感防控的重点时期。应进一步加强监测,研究本地区流感活动特点。
Objective To understand the characteristics of influenza virus in Anhui Province and provide basis for scientific prevention and control of influenza. Methods The results of pathogenic tests of influenza-like specimens in the influenza surveillance sentinel hospitals in Anhui Province from 2010 to 2015 were statistically analyzed. Results The positive rates of influenza-like cases in Anhui province from 2010 to 2015 were 9.44%, 12.83%, 8.40%, 14.95% and 13.28%, respectively. Overall, there was a trend of alternating or common epidemic of H3, The winter and spring peak will inevitably occur, mostly in January to March; the summer peak next year, mostly in July to September; influenza A virus in the summer and winter and spring high, while the B-type influenza is only high in winter and spring.
