After a one-year rollout of the pandemic caused by SARS-CoV-2, the continuous
dissemination of the virus has generated a number of variants with increased transmissibility …

SARS-CoV-2 is constantly evolving, leading to new variants. We analysed data from 4400
SARS-CoV-2-positive samples in order to pursue epidemiological variant surveillance and …

This article discusses the epidemic situation of Covid-19 in Brazil, in the face of the
emergence of a new strain called P. 1, which is more transmissible and may be associated …

Abstract Objectives Variants of concern (VOCs) of severe acute respiratory syndrome
coronavirus-2 (SARS-CoV-2), such as the Delta variant and the Omicron variant, have …

The high need of rapid and flexible tools that facilitate the identification of circulating SARS-
CoV-2 Variants of Concern (VOCs) remains crucial for public health system monitoring …

Some of the lineages of SARS-CoV-2, the new coronavirus responsible for COVID-19,
exhibit higher transmissibility or partial resistance to antibody-mediated neutralization and …

The SARS-CoV-2 variant of concern (VOC) gamma (P. 1) has increased transmissibility and
resulted in elevated hospitalization and mortality rates in Brazil. We investigated the clinical …

Abstract Since early 2021, SARS‐CoV‐2 variants of concern (VOCs) have been causing
epidemic rebounds in many countries. Their properties are well characterized at the …

Background This study aims to identify the causative strain of SARS-CoV-2 in a cluster of
vaccine breakthroughs. Vaccine breakthrough by a highly transmissible SARS-CoV-2 strain …

Objectives The emergence of SARS-CoV-2 variants of concern has led to significant
phenotypical changes in transmissibility, virulence, and public health measures. Our study …
