2023年7月，据报道有两只黑鸟幼崽（Turdus merula）死亡。其中一个是在大伦敦最初爆发USUV的地方发现的，第二个是在剑桥郡的农村。尸检显示非特异性发现，包括脾肿大和肺充血，类似于该物种中先前的USUV感染（Giglia等人，2021年）。这两只鸟的大脑和肾脏样本被提交给动植物卫生署。通过USUV特异性qPCR检测USUV（Jöst等人，自从1996年在南欧首次发现USUV以来，USUV已经广泛传播，成千上万的欧亚黑鸟（Turdus merula）和一些其他物种已经死于感染（Vilibic-Cavlek et al.，2020年）。夏季炎热天气的增加和温和的冬季可能会促进病毒的传播（Ciota & Keyel，2019）。虽然黑鸟报告率的降低与英格兰南部黑鸟的一系列疾病事件报告相结合，指出2020年USUV感染的区域性发生（Lawson et al.，2022年），这是英国在大伦敦地区以外首次确认检测到新冠病毒。
In July 2023, the deaths of two juvenile blackbirds (Turdus merula) were reported. One was found in Greater London at the site of the original USUV outbreak, the second in rural Cambridgeshire. Postmortem examinations revealed non-specific findings including splenomegaly and pulmonary congestion, similar to previous USUV infections in this species (Giglia et al., 2021). Brain and kidney samples from both birds were submitted to the Animal and Plant Health Agency. USUV was detected by USUV-specific qPCR (Jöst et al., 2011) and confirmed by genome sequencing for both birds.Since its first detection in southern Europe in 1996, USUV has spread widely, with thousands of Eurasian blackbirds (Turdus merula) and some other species having succumbed to infections (Vilibic-Cavlek et al., 2020). Increasing periods of hot weather during the summer months and milder winters could promote spread of the virus (Ciota & Keyel, 2019). While a reduction in blackbird reporting rates combined with a cluster of disease incident reports of blackbirds in southern England pointed to regional occurrence of USUV infection in 2020 (Lawson et al., 2022), this is the first confirmed detection of the virus in the UK outside the Greater London area.
