The emergence of the SARS-CoV-2 Beta (B.1.351) variant in November 2020 raised concerns of increased transmissibility and severity. We describe the epidemiology of 949 confirmed SARS-CoV-2 Beta variant cases in England, identified between December 2020 and June 2022. Most cases were detected in the first 3 months. A total of 10 deaths (1.1%; 10/949) were identified among all cases and of those with travel information, 38 (4.9%; 38/781) cases with hospital admissions within 14 days of a positive test being detected. 52.9% (413/781) cases were imported. This study reinforces the importance of monitoring of travel-associated cases to inform public health response and reduce transmissibility of new variants.
2020 年 11 月，SARS-CoV-2 Beta（B.1.351）变异株的出现引起了人们对其传染性和严重性增加的担忧。我们描述了 2020 年 12 月至 2022 年 6 月期间在英国发现的 949 例确诊的 SARS-CoV-2 Beta 变异株病例的流行病学情况。大多数病例是在前 3 个月发现的。在所有病例中，共发现 10 例死亡（1.1%；10/949），在有旅行信息的病例中，在检测呈阳性后 14 天内住院的 38 例（4.9%；38/781）。52.9%（413/781）的病例为输入性病例。本研究强调了监测与旅行相关病例的重要性，以便为公共卫生应对措施提供信息，并降低新变异株的传播性。
