California is likely to experience a summer surge in Covid-19 cases due to the new KP.2 variant, which is becoming dominant. Despite increased immunity from vaccines and past infections, rising levels of Covid in wastewater and positive PCR tests indicate a potential uptick in cases, though it may be less severe than previous years.
The new coronavirus variant KP.2, part of the Omicron family, has become the dominant strain in the U.S. It is highly contagious but does not cause more severe disease, and existing vaccines and treatments remain effective. Symptoms are similar to other Covid-19 infections, and home tests are still reliable. High-risk individuals should consider antiviral treatments, and updated vaccines expected in the fall may offer better protection. The CDC recommends isolating until fever-free for 24 hours and symptoms improve, with additional precautions for five days.
