New COVID-19 Variant 'XEC' Driving Winter Surge: What You Need to Know

As COVID-19 activity remains high in the United States, a new hybrid variant called XEC is spreading rapidly in Europe and other parts of the world. The XEC variant has been detected in at least 27 U.S. states so far, and some experts are projecting that XEC could be on track to become the dominant strain this winter. COVID-19 cases are rising to levels not seen since the summer of 2022, according to the Centers for Disease Control and Prevention (CDC). With this uptick in infections, it’s crucial for the public to recognize symptoms, practice safety measures, and stay informed about local health guidelines to protect themselves and vulnerable groups in their communities.

However, despite this increase, official case numbers may not fully reflect the spread of the virus. Many individuals with milder symptoms are not seeking medical attention or testing, leading to significant underreporting. The latest variants, including the newly identified XEC strain, often cause milder symptoms, which can be mistaken for the flu or a common cold. As a result, people may not isolate or take precautions, contributing to what public health experts call a "hidden surge" — a situation where the virus spreads but without a corresponding rise in reported cases or public health interventions.

What is the XEC variant?

The XEC variant, like earlier COVID-19 variants, has mutations in its spike protein, which helps it avoid detection by antibodies in the immune system. These mutations allow the virus to escape immune responses more effectively, making it harder to detect. Despite this, XEC has a somewhat reduced ability to bind cells compared to previous strains, which may explain why its symptoms tend to be milder. Even though it can evade antibodies, this reduced binding can result in less severe illness for most people, often resembling the flu or a mild cold.

Currently, the Centers for Disease Control and Prevention (CDC) defines XEC as a hybrid of the KS.1.1 and KP.3.3 strains from the Omicron family, which became the dominant strain in the U.S. in late 2022.General symptoms of XEC can include:

• High fever of 102.4-to-105.8-degree Fahrenheit
• Shivering
• A new, continuous cough
• Loss or change to your sense of smell or taste.
• Shortness of breath
• Fatigue
• Body aches
• Headache
• Sore throat
• Blocked or runny nose
• Loss of appetite
• Diarrhea
• Feeling sick or being sick

Managing COVID-19 Symptoms

If you have COVID-19, the treatment approach remains largely the same, resting and staying hydrated can help alleviate symptoms. If it's safe for you, taking anti-inflammatory medications can also help with headaches, fevers, and body aches. For mild symptoms, conservative care is often sufficient. It’s crucial to isolate yourself to prevent spreading the virus, particularly to high-risk individuals such as those over 65, infants, and people with certain medical conditions. To effectively self-isolate, stay in a separate room from other household members, use a dedicated bathroom if possible, and avoid sharing personal items.

Tips for Managing Stress and Staying Healthy During Isolation

• Drink plenty of water: aim for 68-101 ounces (2-3 liters) per day. If you have COVID-19, increase your intake by an additional 85-100 ounces (about 2-4 more cups a day).
• Drink electrolyte drinks: Drinks with electrolytes, such as Gatorade Thirst Quencher or Pedialyte Oral Electrolyte Solution, can help restore hydration, especially if you have a fever. 
• Sleep: Rest is essential for recovery. Aim for more than the recommended 7 hours of sleep, as your body requires additional rest to fight off the virus and recover more effectively.
• Diet: A diet rich in vitamins, minerals, and fiber can support your immune system while you recover from COVID-19. Consider including nutrient-dense foods like:
  • Strawberries – Packed with vitamin C, which supports immune health.
  • Eggs – A great source of protein and essential nutrients
  • Antioxidants such as green tea – Help reduce inflammation and support your immune system.
  • Garlic – Known for its immune-boosting properties.
  • Beans and nuts – Both are excellent sources of fiber and protein.
  • Carrots – Rich in beta-carotene, which your body converts into vitamin A to support your immune system.
• Breathing exercises: COVID-19 often affects respiratory function, making it difficult to breathe. Breathing exercises can help restore diaphragm function and increase lung capacity. Try deep breathing by inhaling slowly through your nose, filling your lungs completely, and exhaling slowly through your mouth. Placing a hand on your belly can help ensure you are breathing deeply into your diaphragm.
• Engage in safe hobbies: While isolating, it’s important to keep your mind active and reduce stress. Engage in relaxing, home-based activities such as reading, arts and crafts, journaling, or catching up on your favorite TV shows or podcasts.
• Stay Connected: Isolation doesn’t have to mean feeling alone. Use phone or video calls to stay connected with family and friends. Staying socially connected can help reduce feelings of stress and loneliness.
• Over-the-Counter Medication: Medications like Acetaminophen (Tylenol) or Ibuprofen (Advil) can help reduce symptoms such as fever, body aches, and headaches. However, always consult with your healthcare provider before taking any medications, especially if you’re already on prescribed medications.
• Virtual Visits: If you’re feeling unwell, you can consult a MemorialCare healthcare provider from the comfort of your home through virtual visits.

Emergency Warning Signs of COVID-19

In some cases, COVID-19 symptoms can escalate quickly and may require immediate medical attention. While the XEC variant of COVID-19 is known for generally causing milder symptoms compared to previous strains, severe cases can still occur, especially in vulnerable populations such as older adults or those with preexisting conditions. If you experience any of the following extreme symptoms, it’s important to seek medical care right away.

• Trouble breathing or not being able to catch your breath.
• Skin, lips, or nail beds that are gray or blue.
• Trouble staying awake or waking up.
• Chest pain or pressure that is constant.
• Dry cough or fever that doesn’t go away.
• Significant or worrisome cough that is increasing.
• Confusion or sudden change in mental status

Even though the XEC variant may present with milder symptoms, these severe signs should not be ignored, as they indicate that the virus is affecting your body more seriously. Early medical intervention can help manage these symptoms and prevent complications.

Preventing COVID-19 and the XEC Variant

Preventing the spread of COVID-19 requires continued vigilance. Vaccination remains the most effective tool to reduce the risk of severe illness and protect vulnerable populations. According to the CDC, those who received the updated COVID-19 vaccine were 54% less likely to contract the virus. In addition to vaccination, there are several important steps you can take to prevent COVID-19, including the XEC variant:

• Wear a Mask: Wearing a well-fitted mask, especially in crowded or indoor settings, helps reduce the spread of respiratory droplets, which can carry the virus. This is especially important in areas with high transmission rates or if you're around vulnerable individuals. The CDC recommends wearing masks such as N95, KN95, or KF94 respirator. 
• Practice Good Hand Hygiene: Regularly wash your hands with soap and water for at least 20 seconds or use hand sanitizer with at least 60% alcohol if soap and water aren’t available. Avoid touching your face, especially your eyes, nose, and mouth, which are entry points for the virus.
• Maintain Physical Distance: Try to maintain a safe distance (at least 6 feet) from others in public places, especially in indoor or poorly ventilated areas where the virus can spread more easily. This is particularly important during times of increased transmission, like during flu or COVID-19 season.
• Improve Indoor Ventilation: Good ventilation reduces the concentration of viral particles indoors. Keep windows and doors open if possible or use air purifiers with HEPA filters to improve airflow, particularly in places where people gather.
• Avoid Large Gatherings: Limit participation in large gatherings or crowded events, especially indoors, as these environments provide ideal conditions for the virus to spread. If gatherings are necessary, opt for outdoor settings where fresh air can circulate freely.
• Stay Home if You Feel Sick: If you're experiencing any COVID-19 symptoms, including those associated with the XEC variant (fever, fatigue, cough, body aches), stay home, isolate, and get tested. Early detection can prevent further spread.
• Get Tested Regularly: Even if you're not experiencing symptoms, regular COVID-19 testing can help detect asymptomatic cases, particularly if you've been in close contact with someone who has tested positive.
• Boost Your Immune System: Eat a balanced diet rich in vitamins and nutrients, get plenty of rest, and exercise regularly to strengthen your immune system. This can help your body fight off infections, including COVID-19.
• Disinfect High-Touch Surfaces: Frequently disinfect high-touch surfaces such as door handles, light switches, and mobile phones. The virus can survive on surfaces, so cleaning these areas regularly helps minimize the risk of transmission.
• Stay Up to Date on COVID-19 Boosters and Flu Shots: In addition to the initial COVID-19 vaccination, it’s important to stay up to date on any recommended booster shots. Also, consider getting your annual flu shot, as flu season and COVID-19 can overlap, compounding public health risks.

Even though the XEC variant may cause milder illness, taking these precautions helps slow the spread of the virus and protects those most at risk of serious complications.
