评估通过明信片等纸张传播病毒的风险非常重要。然而，严重急性呼吸综合征冠状病毒2型（SARS-CoV-2）和甲型流感病毒（IAV）在不同类型的纸张上的稳定性目前尚不清楚。研究这些病毒在不同类型纸张上的存活时间，将有助于了解它们通过邮件长途运输的风险。我们评估了SARS-CoV-2和IAV与培养基混合后，在具有各种涂层的明信片表面上的稳定性，包括普通纸（PP），喷墨纸（IP）和喷墨照片纸（IPP）。用显微镜评估每张纸的表面结构。PP、IP和IPP的表面结构根据涂层的存在或不存在以及类型而变化很大，与基材无关。IP和IPP表面比PP表面更不利于病毒存活，因为表面形状的差异。SARS-CoV-2在每张纸上的存活时间约为59.8（PP），6.5（IP）和9.8 h（IPP），显著长于IAV（分别为10.3，1.8和3.3 h）。SARS-CoV-2通过明信片等纸张传播的风险明显高于IAV传播。虽然PP、IP和IPP具有相同的基础材料，但它们的表面结构不同，这影响了病毒的稳定性。IP和IPP表面不太适合病毒存活。这项研究为通过纸张传播病毒的风险提供了新的见解。
The assessment of the risk of virus transmission through papers, such as postcards, is important. However, the stability of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza A virus (IAV) on different types of papers is currently unknown. Investigation of the survival time of these viruses on different types of papers will provide insights into their risk of long-distance transport by postal items. We evaluated the stability of SARS-CoV-2 and IAV, mixed with a culture medium, on the surface of postcards with various coatings, including plain paper (PP), inkjet paper (IP), and inkjet photo paper (IPP). The surface structure of each paper was microscopically assessed. The surface structures of PP, IP, and IPP varied greatly depending on the presence or absence, and type, of coat layer, regardless of the base material. IP and IPP surfaces were less conducive to virus survival than PP surfaces, because of the difference in surface shapes. The survival times of SARS-CoV-2 on each paper were approximately 59.8 (PP), 6.5 (IP), and 9.8 h (IPP), and significantly longer than those of IAV (10.3, 1.8, and 3.3 h, respectively). The risk of SARS-CoV-2 transmission via paper, such as postcards, is significantly higher than that of IAV transmission. While PP, IP, and IPP have the same base material, their surface structures differ, which affects viral stability. The IP and IPP surfaces are less suitable for virus survival. This study provides novel insights into the risks of viral transmission via paper.
