A new set of COVID-19 variants, known as FLiRT, has recently been discovered through wastewater surveillance by the Centers for Disease Control and Prevention (CDC). These FLiRT variants are now responsible for a significant portion of COVID-19 cases in the United States, accounting for 25% of infections.
Among the FLiRT variants, KP.2 has emerged as the dominant variant in the US, surpassing the previously prevalent JN.1 variant. These FLiRT variants are part of the Omicron family and are descendants of the JN.1.11.1 variant.
Symptoms of COVID-19 caused by the FLiRT variants include fever, cough, sore throat, shortness of breath, and more. It is important to note that regular COVID-19 tests cannot determine which variant caused the infection, but genomic sequencing can provide this information.
In terms of protection against the FLiRT variants, staying up to date with booster shots can offer some defense. Additionally, engaging in outdoor activities, avoiding high-risk settings, wearing masks, and practicing frequent handwashing can help reduce the risk of infection.
For vulnerable individuals, a new monoclonal antibody called Pemgarda may serve as a preventive measure against the FLiRT variants. It is crucial for individuals to stay informed on the latest developments and recommendations from health authorities in order to protect themselves and others from the spread of these variants.
