A heavily mutated new COVID-19 strain is quietly making its rounds across the United States — and health officials are paying close attention. Meet BA.3.2, nicknamed the “Cicada” COVID variant, now detected in at least 25 US states. Here’s everything you need to know, calmly and clearly.

Why Is It Called “Cicada”?

BA.3.2 was nicknamed “cicada” by T. Ryan Gregory, a professor of evolutionary biology at the University of Guelph — the same researcher who coined variant names like “stratus” and “pirola.” Like the insect it’s named after, BA.3.2 spent its first years largely underground before re-emerging as a potential major variant.

The analogy is fitting — and a little unnerving. Just like cicadas disappear for years before suddenly showing up everywhere, this variant has been quietly lurking since late 2024.

Which US States Have Been Affected?

CDC data tracked the presence of BA.3.2 in 25 states, including California, Connecticut, Florida, Hawaii, Idaho, Illinois, Louisiana, Maine, Michigan, Maryland, Massachusetts, Missouri, New Hampshire, New Jersey, Nevada, New York, Ohio, Pennsylvania, Rhode Island, South Carolina, Texas, Utah, Vermont, Virginia, and Wyoming.

Detection has primarily been through wastewater surveillance — 132 wastewater samples from 25 US states, nasal swabs from four travelers, three airplane wastewater samples, and clinical samples from five patients. CDC

How Dangerous Is It — Really?

Here’s the balanced truth: there’s no evidence that BA.3.2 is causing more severe disease or hospitalizations in countries where it’s more widespread. Experts note it looks alarming on paper due to its high mutation count, but hasn’t made a significant impact in terms of serious illness in most places yet.

That said, the variant carries 70 to 75 mutations in its spike protein, setting it apart from JN.1 and LP.8.1 — the strains targeted by current COVID-19 vaccines — raising concerns about partial immune evasion. Washington Times

Existing antiviral drugs remain effective against BA.3.2, and vaccines are still expected to protect against severe disease, even if their effectiveness against infection may be reduced. U.S. News & World Report

FAQs

Q: What are the symptoms of the BA.3.2 Cicada COVID variant?

Symptoms are similar to other circulating COVID strains — fever, cough, fatigue, and sore throat — and generally resolve on their own with rest and supportive care.

Q: Is the Cicada COVID variant more dangerous than previous strains?

No — experts say there is currently no evidence of increased severity or hospitalizations, though its high mutation count warrants ongoing monitoring by health authorities.
