COVID Variant Spread: US Surveillance Lags | Is It Already Widespread?

The news coming out of the CDC this week about the BA.3.2 COVID-19 variant, nicknamed “cicada,” feels…familiar. It’s a subtle shift, a re-emergence of concern in a city like Chicago that’s been largely trying to move on. While cases remain relatively low nationally, the fact that this heavily mutated strain has been detected in 25 states, including Illinois, is a reminder that this virus isn’t finished with us. The question isn’t necessarily whether we’re heading for another major surge, but rather how prepared Chicagoans are – and *should* be – for a potential uptick in infections, especially as we head into the spring allergy season when symptoms can overlap.

Understanding the “Cicada” Variant: A Slow Burn

The story of BA.3.2 is unusual, mirroring the life cycle of its namesake insect. First detected in a respiratory sample in South Africa in November 2024, it simmered quietly for over a year before gaining traction last fall. This slow, steady rise is what makes it different from some of the earlier variants that exploded onto the scene. According to virologist Andrew Pekosz, Ph.D., at the Johns Hopkins Bloomberg School of Public Health, BA.3.2 stands out because of the sheer number of genetic changes in its spike protein. These mutations could allow the virus to evade immunity gained from previous infections or vaccinations. A recent study published in the CDC’s Morbidity and Mortality Weekly Report supports this concern.

The World Health Organization classified BA.3.2 as a “variant under monitoring” in December 2025, signaling that public health officials are keeping a close eye on its evolution and spread. The variant’s ability to potentially bypass existing immunity is particularly concerning, given that many Chicago residents haven’t received a COVID-19 booster in over a year. The National Wastewater Surveillance System (NWSS) has been instrumental in tracking BA.3.2’s presence in the US, and data from February 11th shows detections in Illinois, specifically in wastewater samples.

Chicago’s Vulnerabilities and the Role of Surveillance

Chicago, a major transportation hub with O’Hare International Airport and Midway International Airport, is particularly susceptible to the introduction and spread of new variants. The city’s dense population and reliance on public transportation – the ‘L’ trains, buses, and Metra – can as well facilitate transmission. While the NWSS provides valuable data, it’s important to remember that surveillance isn’t comprehensive. Chances are, BA.3.2 has already spread to more Illinois communities than currently reported.

The Cook County Department of Public Health has been working to promote vaccination and booster uptake, but reaching all segments of the population remains a challenge. The disparities in healthcare access and vaccine hesitancy that were evident during the initial phases of the pandemic continue to exist. The decline in widespread testing means that many cases are likely going undetected, making it hard to accurately assess the true extent of the variant’s spread. The University of Chicago Medicine and Northwestern Memorial Hospital are both actively monitoring for new variants, but their capacity is limited.

The Impact on Local Healthcare Systems

While current hospitalizations remain relatively stable, a significant increase in cases could strain Chicago’s healthcare system. Rush University Medical Center, for example, could face increased pressure on its ICU beds and staffing levels. The potential for long COVID, even with milder infections, also adds to the long-term burden on the healthcare system and the city’s economy. The Illinois Department of Public Health is urging residents to stay up-to-date on their vaccinations and to practice good hygiene, such as frequent handwashing and wearing masks in crowded indoor settings.

Navigating the New Normal: A Local Resource Guide

Given my background in public health preparedness, if this trend impacts you in the Chicago area, here are three types of local professionals you might need to consider consulting with, not necessarily because you’re sick, but to proactively prepare for potential disruptions or health concerns:

Independent Insurance Brokers Specializing in Supplemental Health Coverage

Look for brokers with a strong understanding of short-term disability insurance, critical illness insurance, and accident insurance. These policies can provide a financial safety net if you experience a prolonged illness or hospitalization. Verify they are licensed in Illinois and have a proven track record of assisting clients with navigating complex health insurance options. Focus on brokers who represent multiple insurance carriers to ensure you receive unbiased advice.

Estate Planning Attorneys with Healthcare Proxy Expertise

It’s crucial to have an updated estate plan that includes a healthcare proxy, also known as a durable power of attorney for healthcare. This document designates someone to make medical decisions on your behalf if you are unable to do so. Seek an attorney specializing in estate planning with specific experience in healthcare directives. Ensure they are members of the Illinois State Bar Association and can provide clear, concise explanations of your options.

Certified Financial Planners Focused on Emergency Fund Management

An unexpected illness can create significant financial hardship. A Certified Financial Planner (CFP) can help you assess your financial situation and develop a plan to build or strengthen your emergency fund. Look for a CFP who is fee-only (meaning they don’t earn commissions on products they recommend) and has experience working with clients facing health-related financial challenges. Verify their credentials through the CFP Board.
