本研究旨在调查公共场所中 SARS-CoV-2 的存在情况，并评估配备高效颗粒空气 (HEPA) 过滤器的廉价空气净化器用于病毒检测的效用。样本是从 2022 年 2 月至 2022 年 5 月从佛罗里达州迈阿密西北部服务不足的少数族裔社区的六个社区组织收集的。使用逆转录定量聚合酶链反应 (RT-qPCR) 检测空气净化器过滤器和表面拭子中的 SARS-CoV-2。在测试的 32 个过滤器中，有 3 个过滤器呈阳性，但没有发现表面拭子呈阳性。值得注意的是，阳性样本完全来自儿童日托中心。这些发现强调了 SARS-CoV-2 在室内空气中通过空气传播的可能性，特别是在儿童日托中心。此外，该研究还证明了现成的 HEPA 过滤器在检测病毒方面的有效性。改善室内通风和实施空气过滤系统对于减少人们聚集的地方的 COVID-19 传播至关重要。采用 HEPA 过滤器的空气过滤系统为病毒检测和降低传播风险提供了一种有价值的方法。未来的研究应该探索该技术在早期识别和缓解病毒爆发方面的适用性。
This study aims to investigate the presence of SARS-CoV-2 in public spaces and assess the utility of inexpensive air purifiers equipped with high-efficiency particulate air (HEPA) filters for viral detection. Samples were collected from six community-based organizations in underserved minority neighborhoods in Northwest Miami, Florida, from February to May 2022. Reverse transcription–quantitative polymerase chain reaction (RT-qPCR) was used to detect SARS-CoV-2 in air purifier filters and surface swabs. Among 32 filters tested, three yielded positive results, while no positive surface swabs were found. Notably, positive samples were obtained exclusively from child daycare centers. These findings highlight the potential for airborne transmission of SARS-CoV-2 in indoor air, particularly in child daycare centers. Moreover, the study demonstrates the effectiveness of readily available HEPA filters in detecting the virus. Improving indoor ventilation and implementing air filtration systems are crucial in reducing COVID-19 transmission where people gather. Air filtration systems incorporating HEPA filters offer a valuable approach to virus detection and reducing transmission risks. Future research should explore the applicability of this technology for early identification and mitigation of viral outbreaks.
