The Centers for Disease Control and Prevention (CDC) is warning about a new group of COVID-19 variants spreading across the United States, collectively called “FLiRT.” While COVID-19 cases and hospitalizations have declined recently, the emergence of these variants highlights the continued importance of staying vigilant.
FLiRT Variants: A Cause for Concern?
FLiRT stands for a group of variants descended from the JN.1 lineage of Omicron. One particular variant, KP.2, has become especially prevalent, accounting for roughly 25% of new US cases in late April. Scientists are still learning about FLiRT, but some features raise concern:
- Increased Transmission: FLiRT variants may be more transmissible than previous variants, potentially leading to a rise in cases.
- Spike Protein Changes: FLiRT variants have mutations in the spike protein, the part of the virus that binds to human cells. These mutations could potentially affect vaccine effectiveness or make the virus more adept at evading the immune system.
Staying Protected
Fortunately, existing measures can help reduce the risk of FLiRT infection:
- Vaccination: Vaccination with updated COVID-19 boosters remains the best defense against severe illness. The CDC recommends boosters for everyone over 65 and high-risk individuals.
- Public Health Measures: Wearing masks in crowded indoor spaces, maintaining good hand hygiene, and social distancing when sick are all effective in reducing the spread of COVID-19, including new variants.
FLiRT Symptoms
FLiRT variant symptoms appear similar to those of previous COVID-19 strains and can include:
- Fever or chills
- Cough
- Shortness of breath or difficulty breathing
- Fatigue
- Muscle or body aches
- Headache
- New loss of taste or smell
- Sore throat
- Congestion or runny nose
- Nausea or vomiting
- Diarrhea
If you experience any of these symptoms, it’s crucial to get tested for COVID-19 to determine the cause and isolate yourself to prevent spreading the virus.
Conclusion
The emergence of FLiRT variants underscores the ongoing nature of the COVID-19 pandemic. Vaccination, public health measures, and staying informed remain our best tools for staying safe and protecting others.
