Coronavirus: ‘Deltacron’ discovery not a mistake, says scientist who claims he found new variant
- Cypriot scientist Leonidos Kostrikis said the new strain did not emerge from a ‘single recombination event’ but as a result of ‘evolutionary pressure’
- He says the new strain combines characteristics of Delta and Omicron. Other scientists have speculated that the findings are a result of lab contamination

A Cypriot scientist defended his assertion that a new strain of Covid-19 exists that combines characteristics of the Delta and Omicron variants.

Other scientists have speculated that Leonidos Kostrikis’s findings are a result of laboratory contamination. But he said in an emailed statement on Sunday that the cases he has identified “indicate an evolutionary pressure to an ancestral strain to acquire these mutations and not a result of a single recombination event”.
Deltacron infection is higher among patients hospitalised for Covid-19 than among non-hospitalised patients, so that rules out the contamination hypothesis, said Kostrikis, a professor of biological sciences at the University of Cyprus and head of the Laboratory of Biotechnology and Molecular Virology.
What is more, the samples were processed in multiple sequencing procedures in more than one country. And at least one sequence from Israel deposited in a global database exhibits genetic characteristics of Deltacron, he said.
