A newly identified, highly mutated COVID-19 variant called BA.3.2, nicknamed “Cicada,” has been detected in at least 25 US states, including Vermont, prompting health authorities to monitor its spread closely as the summer months approach.
In an interview with USA TODAY, Dr. Robert H. Hopkins Jr., medical director of the National Foundation for Infectious Diseases, explained that the variant first appeared in a traveler to the US in June 2025 and remained largely undetected until recent months. “It was nicknamed after the rarely emerging insects because it has largely remained undetected or ‘underground’ since its discovery,” Hopkins said.
The first local case in a US resident was diagnosed in January 2026. Between that time and February 11, the variant was identified in wastewater samples from 132 sites across 25 states, as well as in voluntary nose swabs from travelers, according to the Centers for Disease Control and Prevention (CDC). Cases of BA.3.2 began increasing worldwide in September 2025, with some Eastern European countries reporting that it accounted for up to 30% of infections as of February.
Experts warn that BA.3.2’s highly mutated profile, with 70-75 mutations distinct from the JN.1 lineage the previous predominant US strain enables it to evade both vaccines and natural immunity. Hopkins noted, “I have not seen any data which indicates that Cicada is any more severe than other circulating variants. Severe sore throat is reported as a common symptom along with other typical COVID symptoms.”
The symptoms of the Cicada variant are largely consistent with other COVID-19 infections, including runny or stuffy nose, fever, headache, fatigue, sneezing, sore throat, cough, muscle aches, vomiting, diarrhea, and changes in taste or smell. Some later variants have been associated with “razorblade throat,” an extremely sore throat.
Dr. Rajendram Rajnarayanan, assistant dean of research and associate professor at the New York Institute of Technology College of Osteopathic Medicine at Arkansas State University, emphasised the importance of vaccination and mitigation measures. “If you believe you may have COVID-19 or test positive, the CDC suggests several ways to treat the symptoms and stop the spread.
- Stay home and separate from others.
- Improve ventilation in your home.
- Wear an N95 or other high-quality mask when around other people.
- Keep up to date on COVID-19 vaccines and boosters.
- Monitor symptoms and stay in touch with your healthcare provider.
- Take medications and treatments as prescribed.
- Rest and use over-the-counter medications to manage symptoms like headaches.
- Practice hygiene such as washing hands often and cleaning shared surfaces.
- Use their testing and treatment location tool to find resources in your area.
Get boosted as soon as it’s available. It works against all of the top circulating lineages, including XBB.1.16, EG.5.1, FL.1.5.1, etc.”
