What should people know about the new coronavirus variant? A doctor explains.

Recently, a new coronavirus variant called KP.2, part of the Omicron family, has become the dominant strain in the United States. The variant belongs to the FliRT variant group and has certain mutations in common. From April 28 to May 11, roughly 30% of new cases were caused by KP.2. The variant is highly contagious but does not appear to cause more severe illness. Current vaccines and treatments are still effective against it. Symptoms of infection are similar to other coronavirus variants, and rapid antigen home tests are reliable in detecting KP.2. High-risk individuals should consider antiviral treatments if infected. The CDC recommends isolating until fever-free for at least 24 hours and symptoms show improvement.
