Abstract
in English, Chinese

We analyzed the influenza surveillance data of Children's Hospital of Suzhou University from 2016 to 2018 and estimated the hospitalization burden of children under 5 years old due to influenza infection in Suzhou. The results showed that the influenza virus positive rate of 1 451 severe acute respiratory infection (SARI) cases in Children's Hospital of Suzhou University was 13.6% (95%CI: 11.8%-15.3%; 197 cases), among which the influenza pandemic intensity in 2017-2018 was relatively high, and A/H1N1 was the main pandemic virus. It was estimated that the hospitalization rate of influenza-related SARI in children under 5 years old in Suzhou was 6.9‰ (95%CI: 6.6‰-7.2‰), among which the hospitalization rate of children aged<6 months was higher, up to 11.4‰ (95%CI: 9.9‰-12.8‰).

分析2016—2018年苏州大学附属儿童医院的流感监测数据，估算苏州5岁以下儿童因流感而导致的住院负担。结果显示，苏州大学附属儿童医院1 451例严重急性呼吸道感染（SARI）病例的流感病毒阳性率为13.6%（95%CI：11.8%~15.3%；197例）；2017—2018年度流感流行强度较高，以A/H1N1为流行株。估算苏州5岁以下儿童流感相关的SARI住院率为6.9‰（95%CI：6.6‰~7.2‰），其中<6月龄儿童住院率较高，为11.4‰（95%CI：9.9‰~12.8‰）。.
