Abstract
OBJECTIVE:
To study the epidemical characteristics of influenza/novel influenza A (H1N1) in Shanxi province from 2009 to 2010, and to provide scientific foundations for predicting and controlling the pandemic outbreak of influenza/novel influenza A (H1N1) effectively.
METHODS:
All samples were collected from cases that resemble influenza cases in sentinel hospital and influenza outbreak. The influenza were detected by PCR and isolated by MDCK cell culture method. Finally, Shanxi province surveillance data from May, 2009 to April, 2010 of influenza like illness (ILI) cases and pathogen detections were analyzed.
RESULTS:
In Shanxi province, influenza viruses kept activation in whole year. The predominant pandemic strain in 2009 was novel influenza A (H1N1) virus. The strong peak was around November, 2009 [positive rate: 58.1%, novel influenza A ( H1N1) of the total: 88.1%]. As well, the people infected influenza caused by novel influenza A (H1N1) were mainly under 59-year-old, and the higher positive rates were concentrated in the people from 5-year-old to 24-year-old. In 2010, influenza B (Victoria) viruses were mainly detected from clinical specimens and became the dominant strain.
CONCLUSION:
Surveillance of Influenza liue illnes, (ILI) and etiology, which can promptly reflect the influenza epidemic situation, play a significant role for understanding epidemic rule of influenza/novel influenza A (H1N1).
