A new COVID-19 variant, BA.3.2 nicknamed cicada, has been detected in at least 25 U.S. states. First identified in South Africa in 2024, US cases rose starting in September 2025, with detections coming from travelers and wastewater. The CDC says the mutation may help the virus evade antibodies and appears highly transmissible, though symptoms resemble other COVID variants. Robust surveillance will guide vaccine updates and responses.
A newly identified Omicron subvariant BA.3.2, nicknamed 'cicada', carries many mutations that may help it evade immunity. It has appeared in Europe and in 25 U.S. states, but remains a minority strain with no clear evidence of greater severity or transmissibility. Vaccines are still expected to protect against severe illness, annual booster shots are recommended, and home COVID tests remain effective if not expired.
The BA.3.2 variant (Cicada), an Omicron descendant with many spike mutations, is spreading rapidly in the United States and in about 23 countries. It is not yet shown to be more dangerous, but its differences may reduce how well current vaccines recognize it, underscoring the continued importance of vaccination, especially for people with chronic health conditions. The variant was first detected globally in 2024, reached the US in 2025, and has been found in 29 states and through wastewater data. Practical guidance remains: practice good hygiene, stay home when sick, spend time outdoors, and consult a clinician about personal risk. Wastewater surveillance continues as a valuable early warning tool.
A new COVID-19 variant, BA.3.2—nicknamed the Cicada—has a high number of spike mutations and has been detected in at least 23 countries; while it could partially evade immunity and current vaccines may be less effective against it, it does not yet appear more severe, with vaccines still offering some protection, and public health officials emphasize protecting high‑risk individuals and maintaining standard precautions as surveillance continues.
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.
CDC and WHO are watching BA.3.2, nicknamed 'Cicada,' a highly mutated SARS-CoV-2 variant detected in dozens of countries and rising in the U.S.; vaccines may be less effective at preventing infection but still protect against severe disease, and health officials advise testing, staying boosted, masking when needed, and improving ventilation.
CDC is monitoring BA.3.2, an Omicron descendant with spike mutations that may reduce protection from prior infection or vaccination. It has reached 25 U.S. states and 23 countries, with about 0.55% of recent U.S. cases identified in sequencing, though wastewater data show BA.3.2 in 132 samples across 25 states, suggesting wider spread. It’s too early to tell if it increases illness severity, but older adults and immunocompromised individuals appear most at risk. The variant likely emerged in South Africa and has spread internationally, with Europe reporting faster transmission. Genomic surveillance varies by country, so the true spread may be underestimated. Ongoing monitoring and vaccination remains important, particularly to protect vulnerable settings.
A newly identified Covid variant, BA.3.2, is spreading in the United States with evidence from travelers and wastewater tests across at least 25 states. Descended from Omicron and carrying many spike-protein mutations, it may evade protection from current vaccines. While not yet dominant or associated with more severe disease, scientists warn that vaccines might need updating and continued surveillance is essential.
A new Covid variant, BA.3.2—descended from Omicron—has begun circulating in the United States, detected in travelers, patients, and wastewater samples across more than 20 states and in wastewater from dozens more, with reports spanning at least 25 states and 23 countries. Early lab data suggest BA.3.2 carries spike mutations that may help it evade antibodies generated by current vaccines, prompting monitoring of vaccine effectiveness and potential updates. While not yet the dominant U.S. variant and there’s no clear evidence it causes more severe disease, experts urge vigilance as the virus continues to mutate.
The WHO has identified a new Covid variant, BA.3.2, which shows increased resistance to antibodies and is spreading across Europe, prompting close monitoring and vaccine updates, though current data suggests it does not cause more severe illness.
