As of May 2025, health authorities are closely monitoring a new group of COVID-19 variants commonly referred to as the FLiRT variants, specifically KP.1.1 and KP.2. These are part of the Omicron family, which has been dominant for the past couple of years. While these variants are not causing widespread severe illness, they are notable for their high transmission rate and subtle changes in symptoms.
What’s New About This Variant?
-
These FLiRT variants have evolved with minor genetic changes that help the virus spread more efficiently from person to person.
-
The variants also show a stronger ability to bypass immunity from previous infections or vaccinations, though vaccines still offer good protection against severe disease and hospitalization.
-
Unlike earlier strains, which often caused loss of smell or severe respiratory issues, these new variants tend to cause milder, cold-like symptoms.
Common Symptoms Observed
While symptoms can vary depending on a person’s immunity and age, most reported symptoms of the FLiRT variants include:
-
Runny or congested nose
-
Sore throat
-
Headache
-
Mild to moderate fever
-
Persistent tiredness or fatigue
-
Cough (usually dry)
-
Occasional sneezing and body aches
-
Less commonly: chest tightness or shortness of breath
These symptoms generally appear within 2–4 days of exposure, and most people recover within 3–5 days, especially if vaccinated.
How It Differs from Past Variants
-
Loss of smell and taste is rare with this strain.
-
Faster transmission makes it easier to catch, especially in crowded places.
-
Milder illness, especially in healthy individuals and those who are vaccinated.
Precautionary Measures to Follow
-
Wear masks in crowded or poorly ventilated areas.
-
Stay home if you experience symptoms and get tested if possible.
-
Continue regular handwashing and sanitizing.
-
Keep vaccinations up to date, including boosters when recommended.
