New Covid Variant: What to Know About the Cicada Strain

As the cherry blossoms begin to bloom around the Tidal Basin, and the Nationals prepare for another season at Nationals Park, a new concern is emerging alongside the spring weather in Washington D.C.: a newly identified COVID-19 variant dubbed “Cigarra.” While the city has largely moved past the acute phases of the pandemic, the emergence of this variant, currently under close watch by both the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), warrants attention. It’s a reminder that SARS-CoV-2 continues to evolve, and vigilance remains crucial.

Understanding the Cigarra Variant (BA.3.2)

The variant, scientifically known as BA.3.2 but nicknamed “Cigarra” (or “Cicada” in some reports), first surfaced in South Africa in November 2024. Its arrival in the United States was detected in June 2025, with the first confirmed case involving a traveler arriving from the Netherlands. The moniker “Cigarra” is apt, as the variant remained largely undetected for a period, similar to the cyclical emergence of cicadas. As of February 11, 2025, the CDC reported cases in 23 countries and detected the variant in wastewater samples from 25 U.S. States.

What sets Cigarra apart isn’t necessarily its increased transmissibility compared to other circulating strains, but rather its genetic divergence. It represents a new lineage of the virus, meaning it’s structurally different enough from previous versions to potentially evade some of the immunity built up through prior infection or vaccination. This represents the primary reason for the heightened surveillance by global health organizations.

Why the Concern? Potential for Immune Evasion

The CDC’s primary concern revolves around mutations within the spike protein of the BA.3.2 variant. These mutations have the potential to reduce the effectiveness of existing immunity, whether derived from previous COVID-19 infections or from vaccination. This doesn’t necessarily mean current vaccines are useless, but it does suggest they may offer diminished protection against infection and, potentially, severe illness. The George Washington University’s Milken Institute School of Public Health has been actively monitoring variant evolution and has emphasized the importance of continued genomic surveillance to track the impact of Cigarra.

It’s critical to remember that the SARS-CoV-2 virus continues to cause significant morbidity and mortality worldwide. Even without a dramatic surge in severe cases, a variant that reduces vaccine effectiveness could lead to more frequent infections, placing a strain on healthcare systems and impacting daily life. The Children’s National Hospital in D.C. Has been preparing for potential increases in pediatric cases, emphasizing the importance of staying up-to-date on vaccinations.

Historical Context: The Evolving Virus

The emergence of Cigarra is a stark reminder of the virus’s ability to mutate. Throughout the pandemic, we’ve seen variants like Alpha, Delta, and Omicron emerge, each with its own characteristics and challenges. The constant evolution of the virus underscores the need for ongoing research and adaptation of public health strategies. The National Institutes of Health (NIH) continues to play a critical role in this research, studying viral evolution and developing new countermeasures.

What Does This Mean for Washington D.C. Residents?

While there’s no immediate cause for panic, residents of Washington D.C. Should remain vigilant. The D.C. Department of Health is likely monitoring the situation closely and will provide guidance as needed. Staying up-to-date on COVID-19 vaccinations, including boosters, remains the most effective way to protect yourself and others. Practicing good hygiene, such as frequent handwashing and staying home when sick, also remains important.

Navigating the New Normal: Local Resources

Given my background in public health preparedness, if this trend impacts you in the D.C. Area, here are three types of local professionals you might need to consult, depending on your individual circumstances:

Infectious Disease Specialists

If you have underlying health conditions or are immunocompromised, consulting an infectious disease specialist is crucial. Gaze for a physician affiliated with a major hospital system like MedStar Health or Inova Health, and ensure they have experience managing complex COVID-19 cases. They can provide personalized advice on vaccination, treatment options, and preventative measures.

Occupational Health and Safety Consultants

For businesses and organizations, particularly those with frontline workers, an occupational health and safety consultant can facilitate develop and implement protocols to minimize the risk of COVID-19 transmission in the workplace. Seek consultants with certifications from organizations like the Board of Certified Safety Professionals (BCSP) and experience in infectious disease control.

Estate Planning Attorneys

While not directly related to COVID-19 treatment, the pandemic has highlighted the importance of having an up-to-date estate plan. An estate planning attorney can help you prepare a will, power of attorney, and advance healthcare directives, ensuring your wishes are respected in the event of illness or incapacity. Look for attorneys specializing in estate planning and elder law, and check their credentials with the District of Columbia Bar.
