Coronavirus disease 2019 (COVID-19) is known to cause multi-organ dysfunction during acute infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), with some patients experiencing prolonged symptoms, termed post-acute sequelae of SARS-CoV-2 (refs. ). However, the burden of infection outside the respiratory tract and time to viral clearance are not well characterized, particularly in the brain. Here we carried out complete autopsies on 44 patients who died with COVID-19, with extensive sampling of the central nervous system in 11 of these patients, to map and quantify the distribution, replication and cell-type specificity of SARS-CoV-2 across the human body, including the brain, from acute infection to more than seven months following symptom onset. We show that SARS-CoV-2 is widely distributed, predominantly among patients who died with severe COVID-19, and that virus replication is present in multiple respiratory and non-respiratory tissues, including the brain, early in infection. Further, we detected persistent SARS-CoV-2 RNA in multiple anatomic sites, including throughout the brain, as late as 230 days following symptom onset in one case. Despite extensive distribution of SARS-CoV-2 RNA throughout the body, we observed little evidence of inflammation or direct viral cytopathology outside the respiratory tract. Our data indicate that in some patients SARS-CoV-2 can cause systemic infection and persist in the body for months.
新型冠状病毒病(COVID-19)已知会在严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)急性感染期间导致多器官功能障碍,一些患者会出现长期症状,称为 SARS-CoV-2 后急性后遗症(post-acute sequelae of SARS-CoV-2,PA-SARS-CoV-2)。然而,呼吸道以外的感染负担和病毒清除时间尚不清楚,特别是在大脑中。在这里,我们对 44 名死于 COVID-19 的患者进行了完整的尸检,并对其中 11 名患者的中枢神经系统进行了广泛采样,以绘制和量化 SARS-CoV-2 在人体中的分布、复制和细胞类型特异性,包括大脑,从急性感染到症状出现后七个多月。我们表明 SARS-CoV-2 广泛分布,主要存在于死于严重 COVID-19 的患者中,病毒复制存在于多种呼吸道和非呼吸道组织中,包括大脑,在感染早期。此外,我们在多个解剖部位检测到持续存在的 SARS-CoV-2 RNA,包括在一个病例中,在症状出现后 230 天,大脑各处均存在 SARS-CoV-2 RNA。尽管 SARS-CoV-2 RNA 在全身广泛分布,但我们在外呼吸道以外观察到很少有炎症或直接病毒细胞病理学的证据。我们的数据表明,在一些患者中,SARS-CoV-2 可能会导致全身感染并在体内持续数月。
