(Reuters) -The U.S. Centers for Disease Control and Prevention (CDC) on Friday estimated that BQ.1 and closely related BQ.1.1 make up for 16.6% of the total circulating coronavirus variants in the United States.
The new emerging variants, BQ.1 and BQ.1.1, have spread quickly in the country in the last few weeks, particularly in New York.
The CDC said on Friday that BQ.1 had previously made up 5.8% of circulating variants, while BQ.1.1 had made up 3.6% of all variants.
The two variants are descendants of Omicron’s BA.5 subvariant, which is currently the dominant form of COVID-19 in the country. U.S. regulators have recently authorized vaccine boosters that target it.
Weekly cases in the United States have been falling recently, while hospitalizations are rising this week but are down compared to previous weeks.
New variants are monitored closely by regulators and vaccine manufacturers in case they start to evade protection offered by current shots.
