A new Covid variant, NB.1.8.1, is spreading globally and has reached the U.S. It seems more contagious than the current leading strain, LP.8.1, which could cause a rise in summer cases. However, experts say it’s not more dangerous and doesn’t appear to evade vaccines or past infections significantly. The WHO is watching it but doesn’t see it as a major health threat yet.
This variant is part of the Omicron family and causes symptoms similar to other recent strains. Vaccines will be updated this fall, but may be limited to seniors and people with health conditions. Doctors warn that the U.S. hasn’t had a Covid wave in a while, and booster rates are low, which could lead to a mild surge.
Experts like Dr. Russo and Dr. Roberts believe a summer uptick is possible. So while it’s not time to panic, it’s smart to stay alert and updated on vaccines.
