New COVID Variant with Immune Escape Potential Confirmed in US, 22 Other Countries A highly mutated SARS-CoV-2 variant, BA.3.2, has been detected in the United States and 22 other countries, according to a study published in the Morbidity and Mortality Weekly Report. The variant, first identified in South Africa in November 2024, has been found in nasal swabs from four US travelers, clinical samples from five patients, three airplane wastewater samples, and 132 wastewater surveillance samples across 25 states. BA.3.2 differs from the JN.1 variant and its descendant, LP.8.1, by having 70 to 75 substitutions and deletions in its spike protein gene sequence. This genetic variation could potentially reduce the effectiveness of current vaccines. The CDC notes that BA.3.2 is genetically distinct from the JN.1 lineages that have circulated in the US since January 2024. Genomic surveillance data shows BA.3.2 detections rose in September 2025, with the first US case identified in June 2025 through the CDC’s Traveler-Based Genomic Surveillance program. By January 2026, the variant accounted for about 30% of sequences in Denmark, Germany, and the Netherlands. As of February 11, BA.3.2 made up 0.19% of 2,579 genetic sequences in national surveillance. Researchers caution that limited genomic surveillance capacity in many countries may mean the actual spread of BA.3.2 is underrepresented. Phylogenetic analysis has identified two sublineages, BA.3.2.1 and BA.3.2.2, indicating ongoing viral evolution. Continued monitoring is essential to assess the variant’s impact on public health. --- COVID Vaccines Not Tied to Risk of Sudden Death, Study Shows A Canadian case-control study published in PLOS Medicine found no increased risk of sudden death in young, healthy individuals vaccinated against COVID-19.#south_africa #cdc #sars_cov_2_variant #morbid_mortality_weekly_report #ba_3_2
