INTRODUCTION
We report the results of the active surveillance of influenza infections in hospitalized patients and the evaluation of the seasonality and correlation with temperature and rainfall data.
METHODS
During the 2-year study period, 775 patients were tested for 15 respiratory viruses (RVs).
RESULTS
Most of the 57% of (n=444) virus-positive samples were human rhinovirus and respiratory syncytial virus. However, 10.4% (n=46) were influenza virus (80% FluA; 20% FluB). Age and SARI were significantly associated with influenza. FluB circulation was higher is 2013.
CONCLUSIONS
In the post-epidemic period, influenza remains an important cause of hospitalization in SARI patients.
简介
我们报告了对住院患者流感感染的主动监测结果，并评估了其季节性以及与温度和降雨量数据的相关性。
方法
在为期两年的研究期间，对 775 名患者进行了 15 种呼吸道病毒（RV）的检测。
结果
57%（n=444）的病毒阳性样本中，人鼻病毒和呼吸道合胞病毒占多数。然而，有 10.4%（n=46）为流感病毒（80%为 FluA；20%为 FluB）。年龄和严重急性呼吸道感染（SARI）与流感显著相关。2013 年，B 型流感的流行率更高。
结论
在大流行后期，流感仍然是导致 SARI 患者住院的一个重要原因。
