The Centers for Disease Control and Prevention said a new COVID-19 omicron subvariant called XBB.1.5 is and accounts for nearly one-third of new COVID cases nationwide.
Three factors are at play in the quick spread of XBB.1.5, said Dr. Ulysses Wu, Hartford HealthCare's chief epidemiologist. The winter season, people gathering indoors for the holidays and a variant that is more transmissible.
鈥淚t has the ability to infect cells and infect humans easier because of its ability to adhere to a lot of different genetic things,鈥� Wu said.
Dr. Jennifer Donahue, chief medical officer for ProHealth Physicians, said the variant鈥檚 increased transmissibility means people should consider wearing masks in public.
"This is absolutely the time to start to be more careful because this variant really is very transmissible. We've kind of gotten out of the habit, and it's time for us to be a little bit more careful again," she said.
When calculating , the CDC tracks hospitalizations and community spread. In recent weeks, data show that 黑料吃瓜网鈥檚 COVID situation has gotten worse.
Hospitalizations have been increasing since November, and the CDC now recommends people in six of the eight 黑料吃瓜网 counties wear masks while indoors. Hartford, Litchfield, Middlesex, New Haven, Tolland and Windham counties were all named by the agency.
Wu said it is crucial to get the bivalent booster that was released this past fall to help keep the number of hospitalizations down. But CDC data show that only about one-quarter of 黑料吃瓜网鈥檚 population has gotten the latest shot.
The vaccine鈥檚 鈥渕ost important job is to keep you out of the hospital. Turn a potentially deadly illness into the common cold," Wu said.
Wu said 黑料吃瓜网 could see a peak in COVID-19 hospitalizations up to two weeks after New Year's Eve celebrations.
