A Covid-19 variant has returned with a vengeance. The BA.3.2 version, nicknamed Cicada, has now been found in over 20 states. The virus is highly mutated, making it difficult for vaccines to recognize. Though similar to other viruses, this strain has the potential to become more prevalent.
How dangerous is it? Cicada earned its name because, like the insect, it “first appeared back in 2024, went dormant for a while and resurfaced in the U.S. late last year,” said Northeastern Global News. BA.3.2 descended from the omicron variant of the Covid-19 virus, which made its debut in 2021.
The strain is making its rounds in the U.S. and can cause similar symptoms to other Covid strains, as well as other respiratory viruses, including a runny or stuffy nose, fever, chills, and sometimes nausea and vomiting. These similarities make it difficult to determine whether you have Covid-19 or another illness.
There hasn’t been any data that “indicates that Cicada is any more severe than other circulating variants,” said Robert H. Hopkins Jr., the medical director of the National Foundation for Infectious Diseases, to USA Today. However, “we don’t know how quickly it will circulate or whether it will outrun the other variants that are out there at the moment,” said William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, to Politifact.
What precautions can you take? The current Covid vaccines are “made to protect against strains from the JN.1 lineage of the coronavirus, which have been the most common strains in the U.S. since January 2024,” said Enfield. BA.3.2 doesn’t fill the bill and is “almost a complete stranger” to those in the U.S.
Despite this, experts still recommend getting the vaccine. In addition, the best thing to do is “when sick, get tested,” said Rajendram Rajnarayanan, an assistant dean and associate professor at the New York Institute of Technology’s College of Osteopathic Medicine, to USA Today. “If positive, stay home until better and confirm with a negative test. If that’s not possible, wear a fit N95 mask.”
