New COVID-19 Variant BA.3.2 'Cicada' Spreading: What You Need to Know
3 months agoUS
A new COVID-19 variant, BA.3.2, nicknamed 'Cicada,' is gaining traction in the United States and worldwide. First detected in late 2024, it has now been identified in over 20 countries. Health officials are closely monitoring its spread and potential impact.
Key Insights
•
BA.3.2, or 'Cicada,' is a highly mutated variant descended from Omicron.
•
It has been detected in wastewater samples and travelers across at least 25 US states.
•
The variant carries 70-75 genetic changes in its spike protein, potentially affecting vaccine effectiveness.
•
Symptoms are similar to other COVID-19 variants: runny nose, headache, fatigue, sore throat, and cough.
•
Early data suggests the variant is not necessarily more severe than other circulating strains.
Why this matters: Understanding the characteristics and spread of new variants like BA.3.2 is crucial for informed public health responses and individual preparedness.
In-Depth Analysis
BA.3.2 emerged in South Africa in November 2024 and was first detected in the U.S. in June 2025. Its high number of mutations compared to the JN.1 lineage raises concerns about potential immune evasion. While it's not currently the dominant strain in the U.S., its presence in wastewater samples indicates widespread circulation. The CDC and WHO are monitoring the variant closely to assess its transmissibility and severity. Current vaccines may offer less protection against infection from BA.3.2, but are still expected to protect against severe illness and death. Wastewater surveillance data from mid-March 2026 indicates that BA.3.2 was detected in 3.7% of wastewater samples, with the XFG variant being the dominant strain at 53%.
