There’s a new Covid-19 variant on the block—and it’s spreading fast. Known as XEC, this subvariant of Omicron is moving rapidly across countries like Thailand and alarming health experts around the globe. What makes XEC different? It’s not just more contagious—it spreads up to seven times faster than the seasonal flu. And even worse, its symptoms can easily be mistaken for something less serious.
If you’ve been brushing off a persistent cough or unexplained fatigue, now’s the time to pay attention. Let’s break down the five most common symptoms of the XEC variant and understand why this version of the virus deserves your full attention.
The XEC Variant: What Sets It Apart?
XEC isn’t just another Covid variant. It’s a powerful evolution of Omicron that seems to pass between people at lightning speed. While it’s genetically linked to previous strains, the way it behaves in the body—and the speed with which it spreads—are cause for concern.
This variant doesn’t always hit hard right away, which is why many people may continue their daily routines while unknowingly infecting others. The key? Recognize the early signs. The sooner you do, the better you can protect yourself and those around you.
Coughing: The First Red Flag You Shouldn’t Dismiss
If you develop a persistent dry cough, don’t ignore it. Among all reported XEC cases, coughing is the most common symptom—and often the first. It’s not just a minor tickle. Many patients describe it as an irritating scratchiness that sticks around for days.
According to data from the Assure Covid-19 Lab in the U.S., over 70% of recent XEC cases reported a strong, ongoing cough. And here’s the kicker: the cough can linger even after other symptoms disappear.
Think of your body as a fire alarm. That cough is the siren—it may be annoying, but it’s trying to save your life.

Fever and Chills: Your Immune System in Overdrive
Not everyone experiences fever with XEC, but when it does strike, it comes with classic symptoms: chills, mild to moderate fever, and body aches. The fever typically ranges between 37.5°C and 38.5°C, and it might make you feel like you’ve got the flu. But unlike the flu, XEC spreads faster and sticks around longer.
Dr. Allison Arwady, a leading public health expert in Chicago, notes that for most people, the fever lasts two to three days, but it can be more severe for those with underlying health conditions.
If your body is heating up, it’s not random—it’s going to battle against the virus. And just like any war, early detection gives you a better chance to win.
Fatigue and Brain Fog: When the Tiredness Doesn’t Go Away
Have you ever slept eight hours and still woke up feeling exhausted? That could be a symptom of XEC. Fatigue is more than just being tired—it’s a deep, lingering exhaustion that doesn’t improve with rest.
Studies from Johns Hopkins Medicine suggest that over 40% of Covid-19 patients experience prolonged fatigue, and with XEC, this can also come with difficulty focusing and even mild insomnia.
According to Dr. Emily Landon from the University of Chicago, this fatigue may be linked to how the virus impacts the central nervous system. Your energy isn’t just low—it’s being drained by an invisible force that your body is trying to fight off.
Sore Throat: The Underestimated Early Sign
When you get a sore throat during flu season, it’s easy to dismiss it. But with XEC, a dry, burning throat could be one of the first signs that you’ve been infected. Many patients describe the soreness as sudden and painful—especially when swallowing.
Dr. Jorge Moreno from Yale points out that XEC doesn’t usually bring on a stuffy or runny nose like the flu does. That makes a sore throat stand out even more as an early warning.
So, if your morning coffee suddenly feels like sandpaper on your throat, don’t just shrug it off. It might be more than seasonal irritation.
Loss of Taste or Smell: Still a Covid Signature
While earlier strains of Covid-19 made this symptom notorious, loss of taste or smell remains a key indicator of the XEC variant. It usually kicks in a few days after other symptoms appear, and can last weeks even after recovery.
Dr. Claire Hopkins, an ENT specialist in the UK, says the symptom is caused by inflammation in the nasal and throat regions, which disrupts your sensory nerves. Though not as common as before, this is still one of the biggest red flags that separate Covid from other illnesses.
Imagine biting into your favorite food and tasting nothing—that’s your body waving a red flag in front of your face.

Why Recognizing These Symptoms Matters
The scary part about XEC isn’t just its speed—it’s how sneaky it is. Many people may experience one or two mild symptoms and think it’s just a cold or allergies. But those “minor” signs could make you a link in a dangerous chain of transmission.
The faster we recognize the signs, the quicker we can test, isolate, and treat ourselves. It’s not about fear—it’s about being responsible.
Conclusion: Don’t Wait for It to Get Worse
XEC is here, and it’s not waiting around. With symptoms like cough, fever, fatigue, sore throat, and loss of taste or smell, this variant packs a punch that’s easy to overlook but hard to ignore once it hits.
You don’t need to panic—but you do need to stay alert. Listen to your body. Pay attention to small changes. And most importantly, don’t hesitate to act. Whether it’s getting tested or simply resting at home, every small step counts.
Because in the race against a virus that spreads seven times faster than the flu, being aware is your best defense.
