A new COVID-19 variant called BA.3.2, or “cicada,” is making headlines. This name comes from its behavior, similar to the cicada insect, which appears after dormancy. Though it first emerged in late 2024, it has gained attention again, particularly in Europe and parts of the U.S.
Currently, cicada accounts for only a few U.S. cases, but it has been spotted in 25 states, according to the CDC. This variant features numerous mutations—between 70 and 75—which may help it evade the immune response generated by current vaccines.
Why is this variant on health experts’ radar? It was first identified in South Africa in November 2024 and only appeared in the U.S. in June 2025. Tracking methods, such as analyzing wastewater and patient samples, have been key in monitoring this variant’s spread.
In Northern Europe, cicada has made a stronger impact, accounting for nearly 30% of COVID-19 cases in countries like Germany, Denmark, and the Netherlands this winter.
As for whether cicada is more dangerous than other variants, opinions vary. Dr. William Schaffner, an infectious disease expert, suggests that current data does not indicate increased severity compared to earlier strains. Most symptoms remain consistent with what we’ve seen before, though experts urge continued vigilance.
Vaccination remains crucial. Current COVID-19 vaccines are effective against many circulating strains, but they may provide less protection against cicada. Dr. Donald Milton from the University of Maryland emphasized that while vaccines might not completely prevent infection, they still help protect against severe cases.
For optimal protection, receiving the vaccine annually—similar to the flu shot—is advised. With vaccines being formulated well in advance, there can be mismatches against variants, as seen with the flu vaccine this year.
People over 65 or those with chronic health issues might consider an additional shot in late spring for extra protection against potential summer surges in infections.
Lastly, at-home COVID-19 tests will still detect this variant, as they target stable parts of the virus. Just be sure the test kits are not expired, and if symptoms arise, get tested and consult a healthcare professional.
Overall, while cicada is a variant of concern, ongoing research and vaccination efforts remain our best tools in managing COVID-19’s evolution.
