Abstract

OBJECTIVES

This study aimed to assess the impact of the COVID-19 pandemic on the circulation, prevalence, and diversity of respiratory viruses other than SARS-CoV-2.

METHODS

Between May 2020 and December 2021, 640 nasopharyngeal swabs were collected from individuals with or without respiratory symptoms, all of whom tested negative for SARS-CoV-2. Samples were analyzed for other respiratory viruses using real-time reverse transcription-polymerase chain reaction.

RESULTS

The overall positivity rate for respiratory viruses was 4.37% (95% confidence interval: 2.79-5.96). Rhinovirus was the most common virus detected (1.25%), followed by PIV4 (0.78%), Human Coronavirus 229E (HCoV-229E) (0.62%), and influenza B (0.46%). Influenza A (H1N1pdm09) and Human Coronavirus OC43 (HCoV-OC43) each had a prevalence of 1%. Other viruses, including H3N2, Human Coronavirus NL63 (HCoV-NL63), and Human Coronavirus HKU1 (HCoV-HKU1), were less frequent (0.15%).

CONCLUSIONS

The study reveals a low circulation of respiratory viruses other than SARS-CoV-2 during the period from May 2020 to December 2021. This observation is directly linked to the preponderant circulation of SARS-CoV-2 and the strict measures put in place to limit its transmission.

摘要

目的

本研究旨在评估2019冠状病毒病(COVID-19)大流行对严重急性呼吸综合征冠状病毒2(SARS-CoV-2)以外的呼吸道病毒的传播、流行率和多样性的影响。

方法

在2020年5月至2021年12月期间,从有或无呼吸道症状的个体中采集了640份鼻咽拭子,所有个体的SARS-CoV-2检测均为阴性。使用实时逆转录-聚合酶链反应对样本进行其他呼吸道病毒分析。

结果

呼吸道病毒的总体阳性率为4.37%(95%置信区间:2.79-5.96)。检测到的最常见病毒是鼻病毒(1.25%),其次是副流感病毒4型(PIV4,0.78%)、人冠状病毒229E(HCoV-229E,0.62%)和乙型流感(0.46%)。甲型流感(H1N1pdm09)和人冠状病毒OC43(HCoV-OC43)的流行率均为1%。其他病毒,包括H3N2、人冠状病毒NL63(HCoV-NL63)和人冠状病毒HKU1(HCoV-HKU1),出现频率较低(0.15%)。

结论

该研究揭示了2020年5月至2021年12月期间,SARS-CoV-2以外的呼吸道病毒传播率较低。这一观察结果与SARS-CoV-2的优势传播以及为限制其传播而采取的严格措施直接相关。
