Abstract

Objectives

We conducted surveillance for novel respiratory viruses among patients hospitalized with pneumonia in Sri Lanka and Vietnam.

Methods

We enrolled patients from January 2020 to July 2022 at one major hospital each in Sri Lanka and Vietnam. The participants’ nasopharyngeal swabs were studied with assays for previously recognized viruses as well as for assays for novel viruses.

Results

A total of 401 hospitalized patients were enrolled, 204 from Sri Lanka and 197 from Vietnam. Laboratory analyses detected a number of previously recognized viruses, including influenza A/(H1N1)pdm09, human respiratory syncytial virus B, human respirovirus 3, rhinovirus A59, enteroviruses, and a human mastadenovirus C. Although an assortment of common human coronaviruses was characterized, 18 (43.9%) of 41 coronavirus-positive samples from Vietnam had evidence of the newly described canine-like coronavirus, CCoV-HuPn-2018 (previously only detected in Malaysia and Haiti).

Conclusions

The detection of a novel, possibly emerging virus, CCoV-HuPn-2018, in multiple patients in Vietnam, demonstrates the value of such periodic novel virus surveillance, especially in regions at risk for viral emergence.

在斯里兰卡和越南肺炎住院患者中检测到多种呼吸道病毒

目的对斯里兰卡和越南住院的肺炎患者进行新型呼吸道病毒监测。方法于2020年1月至2022年7月在斯里兰卡和越南各一家大医院招募患者。研究人员对参与者的鼻咽拭子进行了先前识别的病毒和新病毒的检测。结果共纳入住院患者401例，其中斯里兰卡204例，越南197例。实验室分析检测到许多以前识别的病毒，包括甲型H1N1流感病毒pdm09、人呼吸道合胞病毒B、人呼吸道病毒3、鼻病毒A59、肠道病毒和人乳腺病毒c。尽管鉴定出了一系列常见的人类冠状病毒，但来自越南的41个冠状病毒阳性样本中有18个（43.9%）发现了新描述的犬类冠状病毒CCoV-HuPn-2018（以前仅在马来西亚和海地检测到）。结论在越南多名患者中检测到一种可能正在出现的新型病毒CCoV-HuPn-2018，证明了这种定期监测新型病毒的价值，特别是在存在病毒出现风险的地区。
