Cicada Covid Variant: New Strain Spreads – Vaccine Effectiveness Concerns

The news coming out of Europe and increasingly, the United States, regarding a new COVID-19 variant dubbed “Cicada” (BA.3.2) is understandably causing a ripple of concern. While it’s too early to predict a full-blown resurgence like we saw in previous years, the sheer number of mutations this variant carries – potentially 70 to 75 – is prompting health officials to take a closer look. Here in Austin, Texas, where we’ve largely returned to pre-pandemic life, it’s a decent time to revisit preventative measures and understand what this new strain might mean for our community.

Understanding the Cicada Variant

The Cicada variant, first identified in South Africa in November 2024, has a rather unusual pattern of emergence. It initially disappeared for a period before resurfacing and spreading, a behavior likened to the cyclical appearance of cicada insects – hence the name. It’s now been detected in 23 countries, including a growing presence in the US. The variant first appeared in the US in June 2025, with a traveler arriving at San Francisco International Airport from the Netherlands, but didn’t gain significant traction until January 2026. As of February 11th, the Centers for Disease Control and Prevention (CDC) reported identifying it in 25 states, including neighboring states like New Mexico and Oklahoma.

What sets Cicada apart is its high number of mutations. Compared to the JN.1 variants that have been dominant for the past two years, Cicada boasts at least twice the number of mutations. This raises concerns about its ability to evade the immunity provided by previous vaccinations and infections. Dr. Robert H. Hopkins, medical director of the National Foundation for Infectious Diseases, notes that the substantial mutations make it “less likely that the current vaccines will be as highly effective against the variant,” though he stresses the necessitate for more data to fully assess the situation.

Symptoms and Current Assessment

Currently, the symptoms associated with the Cicada variant appear to be similar to those of other COVID-19 strains. The Health Service Executive (HSE) lists common symptoms as fever, dry cough, fatigue, loss of smell or taste, nasal congestion, sore throat, headache, muscle or joint pain, skin rash, nausea, diarrhea, chills, dizziness, shortness of breath, loss of appetite, confusion, and chest pain. However, reports are indicating a particularly common symptom: a severe sore throat.

Importantly, Dr. Hopkins hasn’t observed any evidence suggesting Cicada is more dangerous than other circulating variants. This is reassuring, but it doesn’t negate the need for vigilance. The CDC’s recent report highlights the variant’s ability to efficiently evade antibodies due to spike protein mutations, emphasizing the importance of ongoing genomic surveillance and evaluating the continued effectiveness of vaccines and antiviral treatments.

Cicada and Austin: A Local Perspective

Austin, with its vibrant population and bustling activity, is particularly susceptible to the spread of infectious diseases. The University of Texas at Austin, a major employer and hub of activity, sees a constant influx of students and visitors, creating opportunities for transmission. Similarly, events like South by Southwest (SXSW) and Austin City Limits (ACL) draw large crowds, potentially accelerating the spread of any new variant. The Dell Medical School at the University of Texas at Austin is actively involved in monitoring local trends and providing guidance to the community.

Given the potential for increased transmission, it’s prudent for Austin residents to consider reinforcing their preventative measures. While mask mandates are unlikely to return, individuals may choose to wear masks in crowded indoor settings, especially if they are immunocompromised or at higher risk of severe illness. Staying up-to-date with vaccinations, including the latest COVID-19 boosters, remains the most effective way to protect against severe outcomes. The Austin Public Health department offers regular vaccination clinics and resources for residents.

Navigating the New Landscape: Local Resources

If you’re feeling anxious about the Cicada variant and its potential impact on your health and well-being here in Austin, it’s wise to proactively connect with local professionals who can offer guidance and support. Given my background in public health preparedness, if this trend impacts you in Austin, here are three types of local professionals you need to consider:

• Functional Medicine Physicians: These doctors take a holistic approach to health, focusing on identifying and addressing the root causes of illness. Look for a physician certified by the Institute for Functional Medicine (IFM) who can help you optimize your immune system and develop a personalized wellness plan.
• Certified Health Coaches: A health coach can provide support and accountability as you implement preventative measures, such as improving your diet, increasing physical activity, and managing stress. Seek a coach certified by the National Board for Health & Wellness Coaching (NBHWC).
• Estate Planning Attorneys: While not directly related to health, it’s always a good idea to ensure your legal affairs are in order, especially in light of ongoing health uncertainties. Look for an attorney specializing in estate planning with experience in wills, trusts, and advance healthcare directives. The State Bar of Texas can help you discover a qualified attorney.
