Wastewater signals BA.3.2 COVID-19 variant in 25 states, CDC reports
A new SARS-CoV-2 lineage, BA.3.2, is being tracked in the United States through wastewater and clinical samples, with detections across 25 states including travelers and patients. The variant carries 70–75 spike-protein mutations and has shown immune escape characteristics, potentially increasing infections though not necessarily causing more severe disease. The CDC notes ongoing genomic surveillance is essential as BA.3.2 has two sublineages (BA.3.2.1 and BA.3.2.2) and continues to evolve.
