Influenza burden estimates are essential to informing prevention and control policies. To complement recent influenza vaccine production capacity in Vietnam, we used acute respiratory infection (ARI) hospitalization data, severe acute respiratory infection (SARI) surveillance data, and provincial population data from 4 provinces representing Vietnam’s major regions during 2014–2016 to calculate provincial and national influenza-associated ARI and SARI hospitalization rates. We determined the proportion of ARI admissions meeting the World Health Organization SARI case definition through medical record review. The mean influenza-associated hospitalization rates per 100,000 population were 218 (95% uncertainty interval [UI] 197–238) for ARI and 134 (95% UI 119–149) for SARI. Influenza-associated SARI hospitalization rates per 100,000 population were highest among children <5 years of age (1,123; 95% UI 946–1,301) and adults >65 years of age (207; 95% UI 186–227), underscoring the need for prevention and control measures, such as vaccination, in these at-risk populations.

流感负担估计对于告知预防和控制政策至关重要。为了补充越南近期的流感疫苗生产能力，我们使用了 2014-2016 年代表越南主要地区的 4 个省的急性呼吸道感染（ARI）住院数据、严重急性呼吸道感染（SARI）监测数据和省级人口数据来计算省和全国流感相关 ARI 和 SARI 住院率。我们通过病历审查确定了符合世界卫生组织 SARI 病例定义的 ARI 入院比例。ARI 的平均流感相关住院率为每 100,000 人 218（95% 不确定性区间 [UI] 197-238），SARI 为 134（95% UI 119-149）。每 100 人中流感相关的 SARI 住院率，> 65 岁（207；95% UI 186-227），强调需要在这些高危人群中采取预防和控制措施，例如疫苗接种。
