Results Of the 644 throat swab specimens, 80 (12.4%) were positive for influenza virus nucleic acid, mainly seasonal influenza virus 47 (58.8%) and influenza B virus (37.5%). In the age group of 5-14 years, the positive rate of influenza virus nucleic acid was the highest (22.2%). Similar to both men and women, the positive numbers in the first half of the year accounted for 98.8% (79/80) of the whole year. Conclusions In 2012, the epidemic of seasonal influenza H3 virus in Sanming mainly focused on the first half of the year and the high-risk population aged 5 to 14 years.
