A newly tracked COVID-19 variant known as BA.3.2, also referred to as “Cicada,” is drawing global attention after being detected in 23 countries, with health authorities closely monitoring its spread, including cases identified in the United States.
The variant was first identified in South Africa in November 2024 and has gradually spread across multiple regions, including Europe, North America, Asia, Africa, and Oceania. Its expanding presence has raised concern among researchers due to the unusually high number of mutations observed in its spike protein.
According to recent health data, BA.3.2 carries approximately 70 to 75 spike protein mutations, making it significantly different from earlier COVID-19 strains targeted by existing vaccines. Experts believe these genetic changes may allow the variant to partially evade immunity developed through prior infections or vaccinations.
In the United States, the variant was first detected in June 2025 in a traveler arriving from the Netherlands. Since then, it has been identified through traveler screening, clinical testing, aircraft wastewater analysis, and community wastewater surveillance across several states. Despite this, it still represents only a small percentage of sequenced COVID cases.
Health authorities say there is currently no clear evidence that the Cicada variant causes more severe illness compared to other circulating variants. However, laboratory studies suggest it may have an increased ability to evade antibodies, prompting continued monitoring by global health agencies.
Countries and territories reporting the variant include South Africa, Mozambique, Kenya, Denmark, Germany, the Netherlands, England, Belgium, Czechia, France, Ireland, Italy, Luxembourg, Norway, Slovenia, Spain, Sweden, the United States, Canada, Japan, Singapore, South Korea, Hong Kong, and New Zealand. Experts emphasize that the immediate focus remains surveillance rather than alarm, as officials continue tracking whether the variant alters the broader global risk landscape.
