New COVID Variant 'Cicada' Spreading: What You Need to Know
2 months agoUS
A new, heavily mutated COVID-19 variant called BA.3.2, nicknamed 'Cicada,' is spreading in the United States and has been detected in at least 25 states. This variant, first identified in South Africa in November 2024, is a descendant of the BA.3 omicron subvariant. Health officials are closely monitoring it due to its potential to evade immunity from vaccines or prior infections. This article provides an overview of what you need to know about the 'Cicada' variant, including its origins, spread, symptoms, and the effectiveness of current vaccines.
Key Insights
•
BA.3.2, or 'Cicada,' is a heavily mutated COVID-19 variant spreading in the US and globally.
•
It has been detected in at least 25 U.S. states and was first identified in South Africa in November 2024.
•
The variant has a significant number of mutations in its spike protein, potentially reducing protection from previous infections or vaccinations. Why this matters: This could lead to increased breakthrough infections, even in vaccinated individuals.
•
Current COVID-19 vaccines are expected to continue providing protection against severe disease, but early studies suggest BA.3.2 may evade antibodies from the 2025-2026 shots. Why this matters: This highlights the ongoing need for updated vaccines that target emerging variants.
•
There is no evidence that BA.3.2 causes more severe illness or hospitalizations compared to previous strains. Why this matters: While the variant is spreading, it doesn't appear to be more dangerous than previous strains.
In-Depth Analysis
Background
BA.3.2 emerged over a year ago and slowly simmered until last fall when it started ramping up in several countries, including the U.S. It has 70–75 mutations in its spike protein, setting it apart from other circulating strains. The CDC notes that BA.3.2 represents a new lineage that's “genetically distinct” from the family of variants seen in recent years.
Spread and Detection
As of February 11, 2026, BA.3.2 had spread to at least 23 countries. In the U.S., it has been detected in at least 25 states, with wastewater monitoring data indicating its presence in at least 11% of samples nationally as of late March 2026. States where it has been detected include California, Connecticut, Florida, and Massachusetts, among others.
Symptoms and Severity
The symptoms of BA.3.2 are similar to those caused by other variants, including cough, fever or chills, sore throat, congestion, shortness of breath, loss of smell or taste, fatigue, headache, and gastrointestinal symptoms. Fortunately, there's no evidence suggesting BA.3.2 causes more severe illness or increased hospitalizations.
Vaccine Effectiveness
While BA.3.2's mutations may affect how well vaccines protect against infection, current vaccines are expected to continue providing protection against severe disease. Experts recommend staying up-to-date with vaccinations, especially for those at higher risk of severe illness. If you haven't been vaccinated or infected in the last 6-12 months, consider talking to your doctor about a booster.
FAQs
•
Q: What are the symptoms of the BA.3.2 'Cicada' variant?
The symptoms are similar to other COVID-19 variants, including cough, fever, sore throat, and fatigue.
•
Q: Is the BA.3.2 variant more severe than previous strains?
No, there is currently no evidence that BA.3.2 causes more severe illness or hospitalizations.
•
Q: Are current COVID-19 vaccines effective against the BA.3.2 variant?
Current vaccines are expected to provide protection against severe disease, but may be less effective at preventing infection.
Key Takeaways
•
The 'Cicada' variant is spreading but doesn't appear to be more severe.
•
Vaccines are still your best defense against severe illness.
•
Stay informed and follow public health recommendations.
•
If you experience symptoms, get tested and consult with your healthcare provider.
