As of July 15, 2024, the CDC has reported that three SARS-CoV-2 Omicron subvariants - KP.2, KP.3, and LB.1 - are now highly prevalent in the United States. Notably, the KP.3 variant accounts for approximately 37% of new COVID-19 cases nationwide.
Recent data from the National Wastewater Surveillance System (NWSS) support these findings, indicating increased viral activity in many communities. This wastewater monitoring provides an early warning, identifying trends in SARS-CoV-2 circulation even before clinical cases are reported.
Key points to remember:
- These variants are descendants of the previously dominant JN.1 variant.
- Up-to-date COVID-19 vaccines remain effective in preventing severe illness.
- Current vaccines produce antibodies that can recognize JN.1 and its descendants.
This update underscores the importance of staying informed about emerging variants and maintaining vaccination efforts. For more detailed information on these variants and their implications, visit the CDC's COVID Data Tracker.
