As the COVID-19 pandemic continues to evolve, a new variant called XEC is drawing attention. This recombinant variant has been detected in 25 U.S. states and other countries, including Canada. Although it hasn’t caused a significant surge yet, health experts are keeping a close eye on its spread. Below, we examine the symptoms, transmission rate, and what to expect in the coming months.
What is the XEC Variant?
The XEC variant is a recombinant of two previous variants: KP.3.3 and KS.1.1. These belong to the broader Omicron family, which has dominated COVID-19 cases in recent years. Recombination occurs when a person is infected with two different SARS-CoV-2 variants, allowing their genetic material to combine and create a new strain.
This new variant has spread rapidly across Europe, North America, and Asia. At least 820 sequences have been detected globally, with about 100 found in the U.S. alone. These cases have appeared in states like California, New Jersey, and Virginia. Canada has also begun reporting cases, signaling the virus’s potential for wider distribution.
Symptoms of the XEC Variant
So far, the XEC variant has not demonstrated any unique symptoms compared to other COVID-19 variants. The most common COVID-19 XEC variant symptoms include:
- Sore throat
- Cough
- Fatigue
- Headaches and body aches
- Congestion and runny nose
- Fever or chills
- Shortness of breath
- Nausea or loss of appetite
- Diarrhea
- Loss of taste or smell
Like previous strains, these symptoms may vary in severity depending on the individual. High-risk populations, including the elderly and immunocompromised, may experience more severe illness. However, healthy adults and younger individuals might experience mild or even asymptomatic infections.
Is XEC More Transmissible?
According to infectious disease experts, XEC has a mutation in its spike protein, which may make it more contagious. The XEC variant has been spreading rapidly in countries like Germany, France, and Denmark. Scientists speculate that XEC could soon become the dominant strain in the U.S. and other regions.
That said, the XEC variant behaves similarly to its Omicron predecessors. While it is easily transmitted, there is no evidence that it is causing more severe disease or overwhelming hospital systems.
How XEC is Impacting Canada
In Canada, health authorities are beginning to monitor the XEC variant closely. As respiratory virus season approaches, experts believe that Canada could see an increase in cases. This is particularly concerning as more people gather indoors during colder months. The presence of the COVID-19 XEC variant in Canada adds another layer of complexity to managing public health during the fall and winter seasons.
Will XEC Cause a Fall Surge?
The possibility of a COVID-19 surge this fall remains uncertain. Many experts believe that the XEC variant could drive an increase in cases, especially during the winter months. However, other factors, like natural immunity from previous infections and vaccine uptake, will play a significant role in determining the severity of a potential surge.
The U.S. experienced an extended summer wave of COVID-19 activity, which may reduce the likelihood of a severe winter surge. However, the unpredictability of new variants like XEC means that public health officials are urging caution.
Will Vaccines Protect Against XEC?
The U.S. Food and Drug Administration (FDA) recently approved updated COVID-19 vaccines for the 2024–2025 season. These vaccines target the KP.2 variant, which is a close relative of the XEC strain. According to early laboratory studies, the vaccines should provide protection against severe disease caused by the XEC variant.
Dr. Marc Siegel, a senior medical analyst, recommends the updated vaccine, especially for high-risk populations. This includes the elderly, immunocompromised individuals, and those with chronic health conditions. For the general public, getting vaccinated now could help reduce the overall impact of the XEC variant this winter.
How to Protect Yourself Against XEC
As we head into colder months, here are a few key ways to protect yourself against the COVID-19 XEC variant symptoms and its spread:
- Stay up to date with vaccinations.
- Test for COVID-19 if you develop symptoms or have had close contact with someone infected.
- Isolate if you’re feeling unwell to avoid spreading the virus.
- Practice good hygiene by washing your hands regularly.
- Avoid crowded indoor spaces or wear a mask to reduce your risk of infection.
- Improve ventilation in indoor areas where possible.

The Road Ahead
While the COVID-19 XEC variant in Canada and the U.S. remains a concern, it is not yet cause for alarm. As health authorities monitor the virus’s spread, vaccines and preventive measures will continue to play a crucial role in controlling outbreaks. For now, it’s essential to stay informed, remain cautious, and get vaccinated if eligible.
COVID-19 may continue to evolve, but we have the tools to fight back against emerging variants like XEC. As always, following public health advice and taking appropriate precautions will help minimize the impact of this virus in the months ahead.
