2015-2016監(jiān)測年度貴州省流感病原學特征分析
[Abstract]:Objective to understand the epidemic trend and pathogen characteristics of influenza in Guizhou Province in 2015 / 2016, and to provide evidence for influenza prevention and control in Guizhou Province. Methods the results of influenza virus RT-PCR nucleic acid in nasopharyngeal swabs collected from 13 sentinel hospitals in Guizhou Province from April 1, 2015 to March 31, 2016 were statistically analyzed by descriptive method. Results from April 2015 to March 2016, there were 111175 ILI cases (6.82%) in Guizhou Province, 13 867 samples were positive, the positive rate was 15.89%, the influenza epidemic occurred in Guizhou Province in the whole year, there was a small peak in summer, and reached the epidemic peak in winter and spring. Among the five age groups, the positive rate of 0-year-old group was the highest (40.20%), followed by 5-year-old and 25-year-old age group (25.41% and 19.28%, respectively), and the positive rate of 0-year-old group was the highest (40.20%), followed by 5-year-old and 25-year-old group (25.41% and 19.28%, respectively), and the positive rate of 0-year-old group was the highest (40.20%), followed by 5-year-old and 25-year-old group (25.41% and 19.28%, respectively). The proportion of male was 54.63%, which was 9.26% higher than that of female. Conclusion the epidemic form of influenza in Guizhou Province is severe in 2015 / 2016, and the proportion and positive rate of ILI% are high. Influenza epidemic is mainly in winter and spring, with a small peak in summer, with a variety of epidemic types, mainly seasonal H _ 3B and BV. The main susceptible population is under 15 years old. Men may be more likely to be infected with influenza virus than women.
