The Omicron XE sub-variant of COVID is more transmissible than the currently dominant BA.2 type, data continues to show—but case numbers remain relatively low for now.

Dr. Maria Van Kerkhove, the World Health Organization's COVID-19 Technical Lead, said in a Q&A video on XE on April 9: "Based on an initial analysis of available sequences, there is a slight growth advantage of this recombinant over BA.2, about a 10 percent increase in transmissibility, not ten times as has been reported by some."
