The recombinant “deltacron” mutant of coronavirus leaves many concerned about the future of the pandemic, with concerns that it may combine the pathogenicity of the delta variant with the infectivity of omicrons. Recombination, which is essentially a viral version of the sex, occurs when a single cell is infected with two related viruses at the same time. The genetic material of these viruses can be mixed during replication.

In recent weeks, dozens of potential recombinant SARS-CoV-2 variants have been identified. So why …
