The COVID-19 pandemic continues to evolve, with new variants emerging over time. One of the latest mutations is the XE variant, a recombinant strain combining elements of the Omicron sub-variants BA.1 and BA.2. First detected in the United Kingdom in early 2022, the XE variant has since spread to various countries. Though not yet classified as a “variant of concern,” it remains under close observation by global health authorities.

Understanding the XE Variant

The XE variant is a result of the combination of two Omicron sub-lineages, which makes it a recombinant virus. A recombinant virus occurs when a single person gets infected by two different strains of a virus at the same time. In this case, the XE variant contains elements of the BA.1 and BA.2 sub-variants of Omicron.

What sets the XE variant apart from the other Omicron sub-variants is its potential to spread more quickly. Preliminary studies suggest that it could be 10% more transmissible than the BA.2 sub-variant, which itself was highly contagious. However, it is important to note that research is still ongoing, and more data is needed to understand how the XE variant behaves.

Symptoms of the XE Variant

The symptoms of the XE variant closely mirror those of other Omicron sub-variants. However, due to its similarity to the Omicron strain, most individuals may experience symptoms that are typically milder compared to earlier variants like Delta. Some of the common symptoms associated with the XE variant include:

  1. Cough: A persistent cough is one of the hallmark symptoms of COVID-19.
  2. Sore Throat: Many patients report discomfort and pain in the throat, often accompanied by hoarseness.
  3. Fatigue: Feeling excessively tired and weak, even after rest, is a common complaint among those infected with the XE variant.
  4. Fever: As with most COVID-19 variants, a mild to moderate fever may occur.
  5. Runny Nose and Sneezing: A runny nose and frequent sneezing, typically symptoms of a cold, are increasingly reported among XE variant cases.
  6. Headache: Many people experience mild to severe headaches as part of the infection.
  7. Muscle Aches: Pain and discomfort in the muscles and joints have also been observed.
  8. Loss of Smell and Taste: Though less common in Omicron variants than in the original strain of COVID-19, some XE variant cases still report a temporary loss of taste and smell.

Severe Symptoms:
While the majority of XE variant cases present with mild symptoms, certain groups of people, such as the elderly or those with underlying health conditions, are at risk of developing more severe symptoms. These may include difficulty breathing, chest pain, confusion, and persistent high fever. Immediate medical attention should be sought if any of these symptoms are observed.

Transmission and Spread of the XE Variant

The XE variant, like its predecessors, spreads primarily through respiratory droplets when an infected person coughs, sneezes, talks, or breathes. The variant has shown increased transmissibility, potentially due to its hybrid nature, but the exact reasons for its faster spread are still being studied.

Close contact remains the most significant way of contracting the virus, though it can also be transmitted through contaminated surfaces. The World Health Organization (WHO) and other health agencies continue to monitor the variant closely, but current evidence suggests that vaccines provide protection against severe illness caused by the XE variant.

Vaccination and the XE Variant

Vaccines continue to play a vital role in combating COVID-19, including its variants. The current vaccines, including mRNA vaccines such as Pfizer-BioNTech and Moderna, and viral vector vaccines like AstraZeneca, are believed to provide significant protection against the XE variant, particularly when It comes to avoiding serious sickness, hospitalization, and death.

While the XE variant may evade some immune responses and lead to breakthrough infections in fully vaccinated individuals, the severity of the disease is often lessened. This reinforces the importance of receiving a booster shot, especially for vulnerable populations, to strengthen the immune response and maintain high levels of protection.

Prevention of XE Variant Spread

Preventing the spread of the XE variant follows many of the same guidelines as preventing previous variants. The basic health protocols remain critical, such as:

  1. Wearing Masks: Masks, especially high-quality ones like N95 or KN95, help reduce the transmission of respiratory droplets.
  2. Hand Hygiene: Regular hand washing with soap or using alcohol-based hand sanitizer is essential in preventing infection from touching contaminated surfaces.
  3. Social Distancing: Keeping a safe distance of at least 6 feet from others helps to reduce the risk of airborne transmission.
  4. Good Ventilation: Ensuring proper air circulation in enclosed spaces is key to reducing the virus’s ability to linger in the air.
  5. Getting Vaccinated: Staying up-to-date with COVID-19 vaccinations and boosters is the best defense against severe illness.
  6. Testing and Isolation: Regular testing, especially if symptoms appear, and self-isolation upon a positive result, are necessary to prevent spreading the virus to others.

How Dangerous Is the XE Variant?

The XE variant has not yet been classified as a variant of concern by the WHO, which means that it is not believed to pose a significantly higher risk than earlier variants like Delta or Omicron. However, due to its higher transmissibility, there is still a potential for it to spread rapidly, especially in unvaccinated populations or those with weakened immune systems.

At this stage, there is no evidence to suggest that the XE variant causes more severe illness than Omicron, nor does it seem to significantly evade immunity from prior infections or vaccinations. However, as with all variants, health authorities continue to study it closely.

Conclusion: Stay Vigilant and Informed

The emergence of the XE variant is a reminder that the fight against COVID-19 is ongoing. While current vaccines appear to offer protection, staying vigilant by following preventive measures is critical. Wearing masks, getting vaccinated, maintaining good hygiene, and adhering to public health guidelines are key steps in controlling the spread of this variant.

As the situation evolves, further research will provide more clarity on how the XE variant behaves, particularly in terms of transmissibility and severity. Until then, it’s crucial to stay informed and practice preventive measures to safeguard ourselves and others.

FAQs on the COVID-19 XE Variant:

1. What is the COVID-19 XE variant, and how does it differ from other variants?
The XE variant is a recombinant strain of the Omicron sub-variants BA.1 and BA.2. It may be about 10% more transmissible than BA.2 but does not appear to cause more severe illness compared to other variants.

2. What are the symptoms of the XE variant?
Symptoms of the XE variant include cough, sore throat, fatigue, fever, headache, runny nose, and muscle aches. In severe cases, patients may experience difficulty breathing or chest pain.

3. How can I protect myself from the XE variant?
Preventive measures include wearing masks, practicing hand hygiene, social distancing, improving indoor ventilation, and staying updated with COVID-19 vaccinations and booster shots.
