New COVID Variant “Cicada” (BA.3.2) Tracked in US & Globally

The conversation around COVID-19 is, understandably, a bit wearying. Just when it feels like we’ve settled into a rhythm of seasonal boosters and cautious awareness, a new variant emerges. Right now, that variant is BA.3.2, nicknamed “Cicada” by some experts and it’s been detected in Michigan. While the current risk appears low, the emergence of Cicada serves as a potent reminder that the virus continues to evolve, and staying informed about its potential impact on our communities – like those in Ann Arbor, Detroit, and Grand Rapids – is crucial.

Understanding the Cicada Variant: A Slow Rise in Michigan

The BA.3.2 variant, first identified in South Africa in November 2024, has been quietly spreading. As of mid-February 2026, the Centers for Disease Control and Prevention (CDC) reported its presence in at least 23 countries and 25 U.S. States, including Michigan. Joe Coyle, director of the Bureau of Infectious Disease Prevention at the Michigan Department of Health and Human Services (MDHHS), clarified that the variant currently represents less than 1% of all COVID-19 cases circulating within the state. What we have is a stark contrast to some European countries, where the Cicada variant accounts for as much as 30% of infections.

The nickname “Cicada” isn’t arbitrary. It draws a parallel to the insect’s life cycle – a long period of dormancy followed by a sudden, widespread emergence. The BA.3 variant, from which Cicada descends, hasn’t been a dominant strain in recent years, much like the cicadas lying dormant underground. This makes the current emergence of BA.3.2 particularly noteworthy.

Why the Concern? Mutations and Immune Evasion

The primary reason public health officials are monitoring the Cicada variant so closely isn’t necessarily its immediate severity, but its substantial number of mutations. These mutations occur in the genetic regions that our bodies use to produce antibodies, whether those antibodies are generated through natural infection or vaccination. As Coyle explained, a high number of mutations raises the possibility that the virus can evade the immune system more effectively, potentially leading to increased transmission or more severe illness.

Specifically, the mutations within the spike protein – the part of the virus that vaccines target – are of concern. Because the Cicada variant is significantly different from the JN.1 and LP.8.1 strains used to formulate the 2025-2026 COVID-19 vaccines, there’s a potential for reduced protection from prior infection or vaccination. The CDC’s report highlights this possibility, noting that the mutations could “reduce protection from a previous infection or vaccination.” However, it’s important to note that this is a potential risk, and further research is needed to determine the actual impact.

Current Assessment and Global Perspective

The World Health Organization (WHO) has designated BA.3.2 as a “variant under monitoring,” but their current assessment is relatively reassuring. The WHO states that available evidence suggests the variant poses a low additional public health risk compared to other circulating Omicron descendant lineages. Importantly, they emphasize that existing COVID-19 vaccines are still expected to provide protection against severe illness. This aligns with the MDHHS’s current stance, which is one of cautious monitoring rather than alarm.

Despite the relatively low current levels of infection in Michigan, Coyle emphasizes the importance of continued vigilance. He points out that COVID-19 infection rates have been steadily decreasing in the state, but vaccination rates have also declined. This creates a situation where even a modestly more transmissible or immune-evasive variant could gain traction. He frames it as a “constant reminder” that the virus’s ability to mutate and evade immunity presents ongoing opportunities for increased transmission and potential severity.

Looking Ahead: Protecting Yourself and Your Community

The emergence of the Cicada variant underscores the importance of staying up-to-date with vaccinations and practicing preventative measures. While the current vaccines may not offer perfect protection against infection, they remain highly effective at preventing severe illness, hospitalization, and death. Simple measures like frequent handwashing, staying home when sick, and considering masking in crowded indoor settings can also help to reduce the spread of the virus.

Given my background in public health preparedness, and considering the potential for evolving variants to impact communities across Michigan – from the bustling streets of Detroit to the university towns like Ann Arbor and East Lansing – if you’re concerned about the impact of this trend, here are three types of local professionals Try to consider consulting:

Local Resources for COVID-19 Preparedness

Infectious Disease Specialists:

These physicians can provide personalized risk assessments, guidance on vaccination schedules, and treatment options if you do become infected. Glance for board-certified specialists affiliated with reputable hospitals like the University of Michigan Health System or Henry Ford Health System. They should be actively involved in staying current with the latest variant information.

Occupational Health and Safety Consultants:

For businesses and organizations, these consultants can help develop and implement COVID-19 prevention plans tailored to your specific workplace. They should have experience with risk assessments, ventilation improvements, and employee training programs. Prioritize consultants familiar with Michigan’s specific workplace safety regulations.

Certified Industrial Hygienists:

These professionals specialize in identifying and controlling workplace hazards, including airborne viruses. They can assess ventilation systems, recommend air purification strategies, and conduct air quality monitoring. Look for hygienists certified by the American Board of Industrial Hygiene (ABIH) and experienced in healthcare settings.
