• The latest Omicron subvariant, XBB.1.5, is the most transmissible strain of COVID yet — but does not seem to make people sicker, the World Health Organization has said.
• XBB.1.5 has spread quickly across the northeastern US and accounts for about 41% of confirmed COVID cases across the nation, data from the Centers for Disease Control and Prevention shows.
• Maria Van Kerkhove, the WHO’s COVID-19 technical lead, warned that the number of people infected with XBB.1.5 has doubled in the US about every two weeks.
• “It is the most transmissible subvariant that has been dectected yet,” Van Kerkhove told reporters during a press conference in Geneva on Wednesday.
