Preprint: Evidence for Delta and Omicron recombination in the US

We also identified two independent cases of infection by a Delta-Omicron recombinant virus, where 100% of the viral RNA came from one clonal recombinant.

In both cases, the 5′-end of the viral genome was from the Delta genome, and the 3′-end from Omicron, though the breakpoints were different.

Delta-Omicron recombinant viruses were rare, and there is currently no evidence that the two Delta-Omicron recombinant viruses identified are more transmissible between hosts compared to the circulating Omicron lineages.

So what is a recombinant variant?

According to Swedish virologist, Anders Sönnerborg, “It can be described as two virus strains having sex with each other. They enter a cell and multiply there at the same time. Then they exchange parts of their genes with each other”
