英文摘要:

Background: After the 2009 influenza A(H1N1) pdm09 pandemic, China established its first severe acute respiratory infections (SARI) sentinel surveillance system.

Methods: We analyzed data from SARI cases in 10 hospitals in 10 provinces in China from February 2011 to October 2013.

Results: Among 5,644 SARI cases, 330 (6%) were influenza-positive. Among these, 62% were influenza A and 38% were influenza B. Compared with influenza-negative cases, influenza-positive SARI cases had a higher median age (20.0 years vs. 11.0, p = 0.003) and were more likely to have at least one underlying chronic medical condition (age adjusted percent: 28% vs. 25%, p < 0.001). The types/subtypes of dominant strains identified by SARI surveillance was almost always among dominant strains identified by the influenza like illness (ILI) surveillance system and influenza activity in both systems peaked at the same time.

Conclusions: Data from China′s first SARI sentinel surveillance system suggest that types/subtypes of circulating influenza strains and epidemic trends among SARI cases were similar to those among ILI cases.
