Maria Van Kerkhove, head of the technical group of the WHO Emergency Diseases Unit, confirmed the appearance of the deltacron coronavirus strain in Europe at a briefing. “
It was detected in France, the Netherlands, and Denmark. But a very low level (of infections with this strain) was recorded),” she said.
Van Kerkhove added that deltacron arose when the subspecies of the strain delta AY.4 and omicron BA.1/BA.2 were combined. WHO experts have already discussed this option at a meeting on March 7.
In early January, a group of scientists from the Faculty of Biological Sciences of the University of Cyprus reported the discovery of a new strain of coronavirus – a hybrid of delta and omicron.
In turn, the WHO admitted that this could be the result of an error: contamination of the sample during sequencing, and suggested not to use the name deltacron.
