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.

COVID-19大流行对加蓬上奥古瓦尔省其他呼吸道病毒的影响

目的本研究旨在评估COVID-19大流行对SARS-CoV-2以外呼吸道病毒的循环、流行和多样性的影响。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收集640份鼻咽拭子，所有人的SARS-CoV-2检测均为阴性。使用实时逆转录-聚合酶链反应对样品进行其他呼吸道病毒分析。结果呼吸道病毒总阳性率为4.37%（95%可信区间为2.79 ~ 5.96）。鼻病毒是最常见的病毒（1.25%），其次是PIV4（0.78%）、人类冠状病毒229E (HCoV-229E)（0.62%）和乙型流感（0.46%）。甲型流感（H1N1pdm09）和人类冠状病毒OC43 （HCoV-OC43）的患病率均为1%。其他病毒包括H3N2、人类冠状病毒NL63 （HCoV-NL63）和人类冠状病毒HKU1 （HCoV-HKU1）的发生率较低（0.15%）。结论2020年5月至2021年12月期间，除SARS-CoV-2外，其他呼吸道病毒的传播较少。这一观察结果与SARS-CoV-2的主要传播以及为限制其传播而采取的严格措施直接相关。
