COVID-19 Variants in April 2025: What You Need to Know
As we navigate through April 2025, new SARS-CoV-2 variants continue to emerge, underscoring the evolving nature of the COVID-19 pandemic. While COVID-19 is no longer the global emergency it once was, the virus remains active, and understanding the latest circulating variants is essential for safeguarding individual and community health.
In this article, we break down the key variants currently in circulation, their characteristics, and how to protect yourself using testing, vaccination, and everyday precautions.
Rapid tests remain a vital tool in the medicine cabinet for ongoing infection cycles of COVID-19. Be sure to stay stocked up with market-leading ASSURE-100 rapid tests this season.
Variant Watch: XEC Takes the Lead
What is the XEC Variant?
The XEC variant is the most dominant COVID-19 strain as of spring 2025. It is a recombinant variant, meaning it emerged from the genetic combination of two Omicron sublineages: KS.1.1 and KP.3.3. First detected in Germany in mid-2024, XEC has since become the leading strain in the U.S., accounting for a significant majority of cases.
Key Features:
- High transmissibility: Like other Omicron variants, XEC spreads efficiently.
- Immune evasion: While vaccines still protect against severe illness, XEC has shown a modest ability to evade prior immunity.
- Symptoms: Similar to past Omicron variants, including sore throat, fatigue, cough, congestion, and occasional fever.
Should You Be Concerned?
While XEC is highly contagious, it generally causes mild illness in vaccinated individuals. However, it poses a higher risk to unvaccinated people and those with underlying conditions.
The JN.1 Variant: Still in Circulation
JN.1 was a dominant variant in late 2024 and early 2025. Although it has been overtaken by XEC in many regions, it continues to circulate and contribute to a smaller proportion of cases.
Key Features:
- Moderate immune evasion
- Symptoms nearly identical to XEC
- Still covered by the 2024-2025 COVID-19 vaccines
New Variant on the Radar: FLiRT (KP.2)
The KP.2 subvariant—informally dubbed “FLiRT” due to the specific mutations it carries—is emerging in some regions, particularly in Asia and parts of Europe. U.S. surveillance is monitoring its trajectory.
What We Know So Far:
- KP.2 shares several mutations with XEC and other Omicron offshoots.
- Limited data suggests similar symptoms and transmission patterns.
- Vaccines and boosters are expected to offer protection.
How to Protect Yourself
Even as COVID-19 becomes more manageable, it’s important to take practical steps to reduce your risk:
1. Stay Up to Date on Vaccines
The CDC recommends that all individuals aged six months and older receive the 2024–2025 COVID-19 vaccine. Adults 65+ and immunocompromised individuals may need two doses.
2. Use Rapid Testing for Early Detection
Rapid testing is crucial for detecting infections and preventing spread—especially before gatherings, travel, or when symptoms arise. Get the leading rapid COVID test here.
Why Rapid Home Tests Matter:
- Fast results: Typically available in under 15 minutes
- Convenient: No lab visit required
- Effective: Best used within 5 days of symptom onset or exposure
3. Follow Public Health Guidelines
- Mask in crowded indoor spaces
- Improve ventilation at home and work
- Stay home if you’re sick
- Practice hand hygiene regularly
What About Long COVID?
Though less common in 2025, long COVID remains a concern. Fatigue, brain fog, and respiratory issues can persist for weeks or months. Early treatment and vaccination have shown to reduce the likelihood and severity of post-COVID complications.
How the U.S. Is Tracking Variants
The CDC and partnering agencies continue to monitor SARS-CoV-2 mutations through genomic sequencing and wastewater surveillance. These systems allow public health officials to detect new variants quickly and adapt vaccine strategies accordingly.
Global Perspective
While the U.S. focuses on XEC and JN.1, other countries are dealing with local surges of different variants. For example:
- India is monitoring an increase in BA.2.86 cases.
- Brazil recently reported small clusters of the BN.1 subvariant.
- UK and EU have advised vulnerable populations to update boosters ahead of summer travel.
Final Thoughts
COVID-19 may not dominate headlines the way it once did, but staying vigilant is still crucial. The emergence of new variants like XEC and the ongoing presence of JN.1 and KP.2 show that the virus is far from gone.
Keep up with vaccine recommendations, test when necessary, and take commonsense precautions to stay safe. With the right information and tools—including rapid home tests and up-to-date boosters—you can confidently navigate the COVID-19 landscape this spring.
Rapid tests remain a vital tool in the medicine cabinet for ongoing infection cycles of COVID-19. Be sure to stay stocked up with market-leading ASSURE-100 rapid tests this season.
