BA.3.2, Nicknamed Cicada, Is a New COVID Variant to Watch
Public health officials are keeping tabs on this new and highly mutated coronavirus variant, detected in half the U.S. and 22 other countries.
BA.3.2, Nicknamed Cicada, Is a New COVID Variant to Watch
A newly identified coronavirus variant known as BA.3.2, which has been dubbed "Cicada" by researchers and public health officials, is drawing increased scrutiny as it spreads across the globe. The variant has now been detected in at least 25 states across the United States and in 22 other countries, prompting the World Health Organization and the Centers for Disease Control and Prevention to classify it as a variant under monitoring. Scientists say the subvariant carries a notable number of mutations on its spike protein, raising questions about its potential to evade existing immunity from vaccines and prior infections.
Early genomic sequencing data suggests that Cicada carries more than 30 mutations compared to its parent lineage, several of which are located in regions of the spike protein that are critical for immune recognition. Researchers have noted that some of these mutations have been observed individually in other variants of concern but have not previously appeared together in this particular combination. While laboratory studies are still underway, preliminary findings indicate that the variant may have an increased ability to bind to human cells, which could contribute to higher transmissibility. However, experts caution that it is still too early to draw definitive conclusions about the variant's severity or its ability to cause breakthrough infections.
Public health officials across the country are urging continued vigilance as surveillance efforts ramp up. The CDC has expanded its genomic sequencing programs in coordination with state health departments to track the spread of Cicada more closely. Hospitals in regions where the variant has been detected are monitoring admission rates for any unusual upticks, though so far no significant surge in hospitalizations has been directly linked to the new subvariant. Federal health officials have also stressed that current vaccines and antiviral treatments are expected to provide meaningful protection, even if some degree of immune evasion is confirmed.
Despite the uncertainty surrounding BA.3.2, experts are emphasizing that the public should not panic but should remain proactive about their health. Staying up to date on COVID boosters, practicing good hygiene, and staying home when symptomatic remain the most effective strategies for reducing transmission. Scientists have noted that the nickname Cicada is fitting, as the variant seems to have emerged quietly before surfacing in multiple locations nearly simultaneously. Officials say they will continue to provide updates as more data becomes available in the coming weeks and will not hesitate to elevate the variant's classification if the evidence warrants further action.
