A new COVID variant is beginning to spread—and it’s catching the attention of scientists for an unusual reason. Nicknamed “Cicada,” this strain isn’t just another minor mutation—it’s one that stands apart.
Officially known as BA.3.2, the variant is drawing concern due to a striking number of changes in its spike protein—the part of the virus responsible for entering human cells. These differences could potentially affect how easily it spreads and how well it evades existing immunity.
“Perhaps more concerning is the variant’s slew of genetic changes in its spike protein, which set it apart from other variants circulating,” explained Andrew Pekosz, a virologist at Johns Hopkins Bloomberg School of Public Health.
While mutations are a normal part of how the virus evolves, most recent variants have been relatively similar. BA.3.2, however, is different—carrying an estimated 70 to 75 spike protein mutations, a level that has scientists watching closely.
The nickname “Cicada” comes from the insect known for staying underground for years before suddenly emerging. According to researchers, this variant followed a similar pattern. First identified in South Africa in 2024, it remained largely under the radar—until recently.
Now, it has been detected in over 20 countries and is circulating across at least 25 U.S. states, according to Centers for Disease Control and Prevention.
Despite its unusual characteristics, there is some reassurance. Experts say current COVID-19 vaccines are still expected to provide strong protection against severe illness, even if this variant proves more transmissible.
For now, BA.3.2 represents only a small fraction of global cases. However, in parts of Europe, it has already begun to account for a larger share of infections—raising the question of whether “Cicada” could become the next dominant strain.
At this stage, scientists are watching closely—but say it’s still too early to predict its full impact.
