According to recent reports and expert analysis, the FLiRT COVID-19 variants (including KP.3.1.1, KP.3, and KP.2) are spreading in the United States, particularly during the summer of 2024.
Common Symptoms:
- Mild disease, with most people experiencing:
- Mild cough
- Sore throat
- Runny nose
- Fatigue
- Headache
- Muscle or body aches
- Similar to previous COVID-19 variants, with no new or unusual symptoms reported.
Key Points:
- The FLiRT variants are genetically similar to the previously dominant JN.1 strain, which had milder symptoms compared to earlier COVID-19 variants.
- Early analysis suggests that KP.3.1.1 may be more infectious than previous variants, but does not generally cause severe symptoms.
- People who have had COVID-19 before may experience a more severe illness due to waning immunity or lack of recent booster shots.
- The CDC recommends everyone six months and older receive the 2024-2025 COVID vaccine once it becomes available later this fall.
Prevention and Control:
- Continue to follow public health guidelines, such as wearing masks, social distancing, and frequent handwashing.
- Stay up-to-date with COVID-19 vaccinations and booster shots.
- If experiencing symptoms, isolate promptly and seek medical attention if severe or concerning.
