Understanding the Cicada Variant of COVID-19: BA.3.2

Overview of the Cicada Variant
The BA.3.2 variant, informally known as the "Cicada" variant, is a newly identified strain of COVID-19 that has garnered attention due to its significant mutations. First detected in South Africa in November 2024, it has since spread to at least 25 countries, including the United States, where it accounts for approximately 11% of COVID-19 samples based on wastewater surveillance data from the Centers for Disease Control and Prevention (CDC). The variant is characterized by 70 to 75 mutations in its spike protein, which may enable it to evade immunity from previous infections and vaccinations.
Key Characteristics and Transmission
The Cicada variant primarily affects children, with studies indicating that children aged 3 to 15 are about five times more likely to be infected compared to adults. Despite its mutations, experts assert that BA.3.2 does not appear to cause more severe illness than previous variants. Symptoms remain consistent with those of other COVID-19 strains, including fever, cough, fatigue, and sore throat.
The variant's name reflects its behavior; much like cicadas that emerge after long periods underground, BA.3.2 was initially undetected for years before re-emerging. It was first identified in a traveler from the Netherlands to the U.S. in June 2025, with the first local case diagnosed in January 2026.
Current Impact and Public Health Response
While the Cicada variant is spreading, it currently represents a small fraction of COVID-19 cases in the U.S. and has not shown signs of driving new waves of severe illness. Experts, including Dr. William Schaffner from Vanderbilt University Medical Center, emphasize that existing vaccines still provide protection against severe disease, even if they may not be as effective against this variant specifically.
The CDC has classified BA.3.2 as a "variant under monitoring," indicating that while it is being tracked closely, there is no immediate cause for alarm. Health officials recommend maintaining standard preventive measures, such as vaccination, hand hygiene, and staying home when sick.
Criticism and Concerns
Despite the reassurances from health officials, some experts express concern regarding the variant's potential to evade immunity. Dr. Amesh Adalja from Johns Hopkins Center for Health Security notes that as immunity wanes and vaccination rates decline, the population may become more susceptible to infections from variants like Cicada.
Additionally, the variant's ability to infect children more efficiently raises questions about the implications for public health, particularly as schools and daycares may facilitate its spread.
Conclusion: Monitoring and Future Outlook
As the Cicada variant continues to circulate, public health officials remain vigilant. The CDC and other health organizations will monitor its spread and assess the effectiveness of current vaccines against it. While the immediate threat level remains low, experts caution that ongoing surveillance is crucial to prevent potential surges in cases, particularly as warmer weather approaches and social interactions increase.
In summary, while the Cicada variant presents new challenges, the existing public health measures and vaccination efforts continue to play a vital role in managing COVID-19's impact.
