influenza and coronavirusThese include a new variant called BA.3.2, also known as cicada, which continues to spread along with a variety of other respiratory illnesses and a troublesome stomach virus that is making many Americans sick.
Symptoms associated with most of these viruses are very similar, including runny nose, cough, muscle aches and fever, leading medical professionals to assert that it is nearly impossible to identify the specific illness without testing.
“Cicada” for short BA.3.2 Currently included in the list of variants monitored by the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), its international spread accelerated late last year.
Although it was first discovered in 2024, it only recently began to account for a large proportion of infections, with its share of COVID-19 cases soaring to 30% in some Eastern European countries as of February.
Experts say the mutational signature of BA.3.2 enhances its ability to evade existing vaccination strategies and immune responses that have created resistance to other vaccines. Coronavirus disease Variants.
At the end of last year, influenza A was particularly serious in the United States, mainly because Type A H3N2 Subclade K variant. As the virus began to peak in January, “we started seeing more of the other viruses,” said Marlene Wolfe, an assistant professor of environmental health at Emory University.
“Every year we think of fall, winter and spring as respiratory disease seasons, but the reality is that different viruses emerge throughout the seasons.”
According to the latest data from the Arkansas Centers for Disease Control and Prevention, north dakotaVermont and Wyoming still face moderate respiratory illness, while the rest of the country has lower infection rates.
Rates of RSV (respiratory syncytial virus) remain high in several states, including Michigan, Nebraska, Nevada, South Dakota, Tennessee, West Virginia and Vermont.
The first local case in the United States was detected in January. From then until the latest data available on February 11, the substance was found in wastewater samples at 132 sites in at least 25 states, according to the National Institutes of Health. CDC. In addition, the variant was detected in samples taken from travelers’ voluntary nasal swabs. Global cases began to rise in September 2025.
Hopkins said the variant is considered “highly mutated,” with 70-75 mutations, setting it apart from the JN.1 lineage that has caused the majority of strains in the United States over the past two years.
Similar to many other variants, the symptoms of the Cicada variant are consistent with those of infection with other new coronavirus variants. according to CDCthese may include: runny or stuffy nose, fever, fatigue, cough, sore throat, vomiting and diarrhea.
While mutations may mean that current COVID-19 boosters may be less effective at preventing infection, they may still provide important protection against severe disease and death, especially if vaccine formulations are updated.
Rajendram Rajnarayanan, assistant dean for research and associate professor at the New York Institute of Technology College of Osteopathic Medicine at Arkansas State University, told USA TODAY it’s important to get checked out when you’re not feeling well.
If the result is positive, stay home until you recover and be verified by a negative test. If that’s not possible, a properly fitted N95 mask is recommended, Rajnarayanan said.
“Once launched, it was an instant boost. It works on all top circulating lineages, including XBB.1.16, EG.5.1, FL.1.5.1, etc.,” he added.
