What is the new “Cicada” COVID variant?

“Cicada” COVID variant is being monitored as it spreads

A newly trending COVID-19 variant labeled “Cicada” is drawing attention because it has been detected in multiple locations in the United States and is being monitored by major public-health bodies.

The coverage indicates both the CDC and the World Health Organization are tracking the variant as it gains ground. Separately, another report states that “Cicada” has been detected in at least 25 states, describing it as a highly mutated variant. That kind of genetic change is why surveillance systems flag certain variants even when the day-to-day clinical impact is still being worked out.

What to know for now

• It’s actively monitored by the CDC and the WHO.
• Geographic spread is widening, with detections reported across at least 25 states.
• Symptoms can overlap with other respiratory viruses, and articles aimed at the general public list “what to know” guidance rather than claiming a unique symptom pattern.

Why it matters

Variant monitoring affects public-health decisions, including how labs and clinicians interpret test results, how forecasts are made for waves of illness, and how guidance on prevention and risk assessment may be updated. Even when vaccines and prior infections remain protective against severe disease, new variants can still change transmission dynamics and the likelihood of reinfection.

What isn’t specified here

The stories do not provide details on severity, hospitalization rates, or how transmissible “Cicada” is compared with currently circulating strains. Those answers typically require ongoing epidemiology and lab work after first detections.
