Abstract

INTRODUCTION

SARS-CoV-2variants of concern (VOC) have been described in the UK (B.1.1.7), South Africa (B.1.351) and Brazil (P.1). Among them, the most scarce information has been obtained from the P.1 variant and more data on its global presence and about its spreading dynamics are needed.

METHODS

Whole genome sequencing was performed prospectively on travellers arriving from Brazil and on a random selection of SARS-CoV-2 positive cases from our population.

RESULTS

In this study we report the first SARS-CoV-2 P.1 and P.2 variants exported from Brazil to Spain. The case infected with the P.1 variant, who had only stayed in Rio de Janeiro, required hospitalisation. The two P.2 cases remained asymptomatic. A wider distribution for P.1 variant beyond the Brazilian Amazonia should be considered. The exportation of the P.2 variant, carrying the E484K mutation, deserves attention. One month after the first description of P.1 and P.2 importations from Brazil to Madrid, these variants were identified circulating in the community, in cases without a travel history, and involved in household transmissions CONCLUSION: Whole genome sequencing of SARS-CoV-2 positive travellers arriving from Brazil allowed us to identify the first importations of P.1 and P.2 variants to Spain and their early community transmission.

摘要

介绍

在英国(B.1.1.7)、南非(B.1.351)和巴西(P.1)已经描述了引起关注的 SARS-CoV-2 变体(VOC)。其中,从 P.1 变体获得的信息最少,需要更多关于其在全球的存在及其传播动态的数据。

方法

对来自巴西的旅行者和我们人群中随机选择的 SARS-CoV-2 阳性病例进行了全基因组测序。

结果

在这项研究中,我们报告了首例从巴西出口到西班牙的 SARS-CoV-2 P.1 和 P.2 变体。感染 P.1 变体的病例仅在里约热内卢停留,需要住院治疗。两例 P.2 病例无症状。应考虑 P.1 变体在巴西亚马逊地区以外的更广泛分布。携带 E484K 突变的 P.2 变体的出口值得关注。在首次从巴西进口到马德里的 P.1 和 P.2 报告一个月后,这些变体在没有旅行史的社区病例中被发现并参与了家庭传播。

结论

对来自巴西的 SARS-CoV-2 阳性旅行者进行全基因组测序,使我们能够鉴定出首例进口到西班牙的 P.1 和 P.2 变体及其早期社区传播。
