Should Citizens Be Concerned?
For many Americans, COVID-19 may feel like a chapter that has already been finished, yet scientists and public health officials are once again paying attention as a new variant spreads quietly across the country.
A recently identified strain of COVID-19, known as the BA.3.2 and informally known as the “Cicada” variant, has been detected in at least 25 states through clinical samples and wastewater surveillance. Researchers say that the variant is still being studied, but its spread has raised reasonable questions about how it actually is different from the earlier strains, whether it could lead to another rise in cases, and what Americans should prepare for if infections surge once again.
The Cicada variant is a new branch of the virus SARS-CoV-2, the virus responsible for COVID-19. Scientists and researchers classify it as part of the Omicron lineage, the same family of variants that has dominated global infections since late 2021.
The variant was first identified in South Africa in November of 2024 before appearing in other parts of the world. It had remained largely rare for months before reappearing in larger numbers in late 2025, eventually spreading to more than 20 countries across the world.
In the U.S., early detections were found through airport surveillance and laboratory testing. By early 2026, public health surveillance, including wastewater testing, confirmed its existence in at least 25 states, showing that the variant is circulating across multiple regions. Despite this spread, the variant still represents a small percentage of total COVID-19 cases in the U.S., meaning it has not yet become the dominant strain.
One reason why the Cicada variant is receiving attention is the large number of genetic mutations it carries. Researchers estimate that it has around 70-75 mutations in the spike protein, the part of the virus that allows it to attach to human cells. This spike protein is also the main target of vaccines and immune responses developed in the body from previous infections. Because of these mutations, scientists are studying whether the variant could partially evade existing immunity from vaccines or past exposure to the virus.
However, early research has not shown evidence that the variant causes more severe illnesses than previous strains. Health agencies such as the World Health Organization (WHO) currently classify the Cicada virus as a “variant under monitoring.” This designation means that the virus has genetic changes that could affect its behavior, but does not yet pose a confirmed increased risk compared to existing variants.
Although the Cicada variant belongs to the Omicron family, it appears to have grown and evolved somewhat differently from the variants that have circulated in the U.S. in recent years.
Scientists believe the variant may have circulated quietly for months or even years before becoming much more visible through testing and surveillance. This unusual pattern is one reason researchers gave it the nickname “Cicada,” referring to the insect known for emerging suddenly after long dormant periods underground. Another difference is the variant’s genetic diversity, because it contains so many mutations, scientists are studying whether it may behave differently in terms of transmission or immunity. Still, experts stress that there is no clear evidence yet that it spreads faster or causes worse disease than previous COVID-19 variants.
One of the biggest concerns for many Americans is whether a new COVID variant could lead to another widespread shutdown like those seen in 2020. Most public health experts say another nationwide lockdown is unlikely at this stage. Several factors make the United States far better prepared today than during the early pandemic years. Because of the various factors, scientists believe future responses are more likely to involve targeted health measures rather than nationwide shutdowns.
Still, researchers warn that viruses constantly grow and change. If a variant spreads quickly or significantly reduces vaccine protection, health officials could consider new recommendations such as updated vaccines or temporary restrictions in high-risk environments.
For now, the Cicada variant remains under close watch rather than immediate concern. Yet its spread across dozens of states highlights an important reality that even as life returns to normal for many Americans, the work of tracking and understanding COVID-19 is not finished just yet.
