Philippe Colson of IHU Mediterranee Infection in Marseille, France, lead author of a report published on the health science website medRxiv, said that because there are so few confirmed cases of Deltacron, it’s too early to tell. peer-reviewed to determine whether Deltacron caused the virus to spread rapidly or cause severe illness.
Philippe Colson’s research team described three patients in France infected with a version of the SARS-CoV-2 virus that combines a mutant protein from the Omicron variant with the Delta variant. As an unpublished report by genetics research company Helix has been identified in the US, two other unrelated cases of Deltacron infection have been reported to medRxiv. In the virus research announcement, other groups reported 12 more Deltacron infections in Europe since January 2022, all with Omicron and Delta spikes.

Genetic recombination of the human SARS-Cov-2 virus has been identified as occurring when two variants infect the same host cell. Mr. Colson said: “During the COVID-19 pandemic, two or more variants were circulating at the same time and in the same geographic area. This creates an opportunity for a combination of these two variations“.
According to Colson, his team has designed a PCR test that “can rapidly test samples that are positive for the presence of this virus strain”.
The new study adds to evidence that trained dogs can help screen crowds to identify people infected with COVID-19.
