The Rise of BA.3.2: What You Need to Know About the “Cicada” COVID Variant
A heavily mutated COVID-19 variant, nicknamed “Cicada” and officially designated BA.3.2, is gaining traction across the United States and globally. Detected in at least 25 states as of February 2026, this Omicron subvariant is raising concerns due to its potential to evade existing immunity.
A Highly Mutated Strain
BA.3.2 stands out from other circulating variants due to the sheer number of mutations it carries – approximately 70 to 75 changes in its spike protein compared to earlier JN.1 lineage viruses. This significant genetic shift is what’s prompting closer monitoring by health officials, as it may reduce the effectiveness of prior infections and vaccinations.
Symptoms of the “Cicada” Variant
Currently, symptoms associated with BA.3.2 appear broadly similar to those seen with other recent Omicron variants. Common symptoms include:
- Fever
- Cough
- Fatigue
- Sore throat
- Headache
- Body aches
Some individuals may also experience sneezing, upper respiratory tract infections, nasal congestion, a runny nose, night sweats, skin rashes, or, less frequently, a loss of smell or taste. Asymptomatic infections have also been documented. Symptom severity can vary depending on age, underlying health conditions, and prior immunity.
Why is it Called “Cicada”?
The nickname “Cicada” was coined by a professor of evolutionary biology, drawing a parallel to the insect’s long periods spent underground before emerging. BA.3.2 was first identified in a respiratory sample collected in South Africa in November 2024, and slowly spread internationally before being detected in the U.S. In June 2025.
Tracking the Spread
The CDC has been tracking BA.3.2 through wastewater surveillance, detecting it in samples from 25 states as of February 2026. Wastewater monitoring often identifies the variant before it appears in clinical testing, providing an early warning system.
Immune Evasion Concerns
The large number of mutations in BA.3.2 raises concerns about its ability to evade immunity from previous infections and vaccinations. While current vaccines may still offer some protection, their effectiveness could be reduced.
Frequently Asked Questions
- Is BA.3.2 more dangerous than previous variants?
- There is no current evidence to suggest that BA.3.2 causes more severe illness than other recent variants.
- Are current COVID-19 vaccines effective against BA.3.2?
- Current vaccines may offer some protection, but their effectiveness could be reduced due to the variant’s mutations.
- What should I do if I suspect I have BA.3.2?
- If you experience symptoms, it’s best to consult with a healthcare professional for testing and guidance.
