'Deltacron' COVID-19 infection is not really a thing: WHO

WHO's COVID-19 Technical Lead Maria Van Kerkhove has said that the phrase "Deltacron", which suggests that people have been infected with both the Delta and Omicron variants of COVID-19, "is not really a thing". "In fact what we think that is, is that it's a result of contamination that has happened during the sequencing process," she further said.
