Health officials: COVID-19 subvariant XBB 1.5 makes up majority of cases across New York and the US
The New York State Department of Health says the XBB 1.5 subvariant of COVID-19 makes up over 50% of cases in the state.
The World Health Organization says it's the most transmissible form of omicron to date.
In December alone, it went from causing about 4% of infections in the U.S. to 41%.
Dr. Ashish Jha, the White House COVID-19 response coordinator, says that's a quick increase.
“First of all, this is a new emerging subvariant, and it has risen very quickly across the country. It's gone from being almost non-existent a month ago to now making up a large portion of all the infections, and that increase is very very fast,” she said.
There are 580 COVID cases in Nassau and 618 in Suffolk. The seven-day positivity rate for Long Island is 9.66%.
