Possible recombination between two variants of concern in a COVID-19 patient

Emerg Microbes Infect. 2022 Dec;11(1):552-555. doi: 10.1080/22221751.2022.2032375.

Abstract

We identified an individual who was coinfected with two SARS-CoV-2 variants of concern, the Beta and Delta variants. The ratio of the relative abundance between the two variants was maintained at 1:9 (Beta:Delta) in 14 days. Furthermore, possible evidence of recombinations in the Orf1ab and Spike genes was found.

Keywords: SARS-CoV-2; coinfection; intra-host single nucleotide variations; recombination.
