Abstract

Human bocavirus (HBoV) has been identified as a viral agent with a global presence, especially in young patients with gastrointestinal infections. In this study, we aimed to evaluate the epidemiological patterns of the HBoVs associated with acute gastroenteritis (AGE) in Taiwan. A total of 2994 AGE fecal samples from several diarrhea outbreaks from 2018 to 2022 were analyzed. From the samples, 73 positive samples were detected in three different bocaviruses: 30 (41.1%) were from HBoV1; 37 (50.7%) were from HBoV2; and 6 (8.2%) were from HBoV3, revealing the respective prevalences in AGE of 1%, 1.2%, and 0.2%. HBoV1 and HBoV2 were the two major epidemic agents of HBoVs in Taiwan during this study period and have seasonal distinct patterns with an epidemic peak from October to the following March. Phylogeny reconstruction and evaluation were implemented in Mega X; the results revealed that most HBoV1 strains in Taiwan appeared to be closely related to those strains from other Asian countries. The HBoV2 exhibited substantial genetic diversity and the HBoV3 genes showed discordance of groups.

2018-2022年台湾急性肠胃炎患者中的人博卡病毒循环。

人类博卡病毒（HBoV）已被确定为一种全球性病毒病原体，尤其是在患有胃肠道感染的年轻患者中。本研究旨在评估台湾与急性肠胃炎（AGE）相关的 HBoV 的流行病学模式。我们分析了 2018 年至 2022 年期间数次腹泻暴发中的 2994 份 AGE 粪便样本。在这些样本中，73 份阳性样本检测到三种不同的波卡病毒：其中 30 例（41.1%）来自 HBoV1；37 例（50.7%）来自 HBoV2；6 例（8.2%）来自 HBoV3，显示其在 AGE 中的流行率分别为 1%、1.2% 和 0.2%。在本研究期间，HBoV1 和 HBoV2 是台湾地区 HBoVs 的两种主要流行媒介，且具有明显的季节性特征，流行高峰期为 10 月至次年 3 月。在 Mega X 中进行了系统发育重建和评估，结果显示台湾的大多数 HBoV1 株系似乎与亚洲其他国家的株系亲缘关系密切。HBoV2 表现出很大的遗传多样性，而 HBoV3 基因则表现出群体的不一致性。

期刊介绍： Viruses (ISSN 1999-4915) is an open access journal which provides an advanced forum for studies of viruses. It publishes reviews, regular research papers, communications, conference reports and short notes. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. We also encourage the publication of timely reviews and commentaries on topics of interest to the virology community and feature highlights from the virology literature in the ''News and Views'' section. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
