The emergence of SARS-CoV-2, responsible for the COVID-19 pandemic, has prompted extensive research into its transmission dynamics; yet, a critical aspect that remains underexplored is the post-mortem infectivity of the virus within cadaveric tissues. Understanding the mechanisms by which SARS-CoV-2 maintains infectivity after death is essential, as it raises significant concerns regarding public health and forensic practices. Research indicates that the virus can persist in various tissues, including lung, liver, and kidney tissues, with studies showing that factors such as the time elapsed since death, the presence of underlying health conditions, and environmental conditions at the time of death can influence the level of infectivity in deceased individuals. These findings are not only crucial for establishing safety protocols for forensic investigators who handle cadavers but also for informing public health guidelines that govern the management of bodies during and after outbreaks. As we investigate the implications of post-mortem SARS-CoV-2 infectivity, it becomes imperative to establish comprehensive protocols to mitigate risks associated with the handling and disposal of infected bodies, thereby protecting public health and ensuring the safety of those working in forensic environments. This paper aims to elucidate the mechanisms of infectivity in cadaveric tissues, explore the persistence of the virus in various tissue types, and assess the broader implications for public health and forensic investigations, ultimately contributing to a safer approach in dealing with COVID-19-related fatalities.
导致新冠疫情的严重急性呼吸综合征冠状病毒2(SARS-CoV-2)的出现,促使人们对其传播动态进行了广泛研究;然而,一个尚未得到充分探索的关键方面是该病毒在尸体组织中的死后传染性。了解SARS-CoV-2在死亡后保持传染性的机制至关重要,因为这引发了对公共卫生和法医实践的重大担忧。研究表明,该病毒可在包括肺、肝和肾组织在内的各种组织中持续存在,研究显示,自死亡以来经过的时间、潜在健康状况的存在以及死亡时的环境条件等因素可影响死者的感染性水平。这些发现不仅对于为处理尸体的法医调查人员制定安全规程至关重要,而且对于为在疫情期间和疫情后管理尸体的公共卫生指南提供信息也至关重要。在我们调查SARS-CoV-2死后感染性的影响时,建立全面的规程以降低与处理和处置受感染尸体相关的风险变得势在必行,从而保护公众健康并确保法医环境中工作人员的安全。本文旨在阐明尸体组织中的感染机制,探索该病毒在各种组织类型中的持续存在情况,并评估对公共卫生和法医调查的更广泛影响,最终为处理与新冠疫情相关的死亡事件提供更安全的方法。
