Deltacron: what kind of beast?

“Deltacron” was detected in 25 (according to some sources, 24) patients with coronavirus in Cyprus. Genomic sequences found during sequencing of the virus genome were sent to the international database GISAID. The putative new strain has a genetic basis for the delta, but has incorporated at least 10 mutations from the omicron.

In defense of his theory, Professor Kostrikis said that the detected cases of infection “indicate evolutionary pressure on an ancestral strain to acquire these mutations, and not the result of a single recombination event.” Also, the scientist said that “Deltacron” was found in Israel.

However, not all scientists were in agreement with the conclusion of their Cypriot colleagues that Deltacron is a product of the natural fusion of other strains. So professor at the University of Birmingham (England) Nick Lohman, considers it a “technical artifact.” Another British scientist, geneticist Tom Peacock wrote in his microblog on Twitter that the real recombinants appear several months after the different strains began to circulate together. Doubt about the reality of “Deltacron” and the domestic Rospotrebnadzor.

“On January 7, 2022, 25 sequences of the new“ variant ”of the coronavirus were actually deposited into the international database GISAID. I took the word “option” in quotation marks because, upon closer examination, they turned out to be similar to laboratory contamination, that is, contamination of some samples with others, ”said Kamil Khafizov, head of the scientific group for the development of new diagnostic methods based on sequencing technologies at the Central Research Institute of Epidemiology of Rospotrebnadzor.

While scientists argue about the reality of the Cypriot “Deltacron”, a new real strain B.1.640.2 has been discovered in France. He was identified by travelers who flew from Cameroon, he managed to infect at least 12 people with it. This variant of SARS-COV-2 has 46 mutations, two of which, however, have already been found in previous strains.

It is too early to talk about the danger of B.1.640.2, which does not even have its own name yet. The number of detected infections is small. As well as it is impossible to speak about the origin of this strain. Despite the fact that the “novelty” was brought from Cameroon, it could appear in another country.
