防止传染病传播的最好方法是降低病原体的传播能力。为了实现这一目标，必须进行流行病学监测，以检索关于其传播和扩散途径的数据。本研究探讨了通过0.22 μm微孔过滤检测SARS-CoV-2的可能性。采用带真空泵的过滤系统进行采样，并通过RT-PCR进行分子分析以检测COVID-19病毒。结果发现，SARS-CoV-2可以在空气采样后3 h在0.22 μm过滤器捕获的颗粒物中检测到，唯一的污染区域是患者区附近的区域。研究结果证实了在污染区的漂浮颗粒物中发现这种病毒的可能性，该方法基于通过0.22 μm孔的过滤技术和分子技术（RT-PCR）检测的简单经济的采样方法。高风险区域是靠近COVID-19患者的区域。
The best way of preventing the dispersion of an infectious disease is decreasing the transmissibility of the pathogen. To achieve such a goal, it is important to have epidemiological surveillance to retrieve data about its routes of transmission and dispersion. This study investigated the possibility of SARS-CoV-2 detection using filtration through 0.22 μm pores. A filtration system with vacuum pump was used for sampling, and molecular analysis was performed by RT-PCR for detecting the COVID-19 virus. It was found that SARS-CoV-2 could be detected in particulate matter trapped on 0.22 μm filters 3 h after air sampling, and the only contaminated areas were those near patient zones. The results confirm the possibility of finding this virus in floating particulate matter in contaminated zones, with a simple and economic sampling method based on filtration technology through 0.22 μm pores and detection with molecular techniques (RT-PCR). The higher risk zones were those near patients with COVID-19.
