Why FLiRT Variants are Prevalent
The SARS-CoV-2 virus strains responsible for COVID-19 infections have been the most prevalent strains globally this year, according to the World Health Organization (WHO). These strains are known as “FLiRT” COVID-19 variations due to their specific structure. Gulf News reports that the term “FLiRT” refers to the locations of the mutations shared by these variants on the spike protein of the virus. These mutations can be found in various locations across the region. There are five different FLiRT variants, each with its own unique modifications.
KP.2, one of the FLiRT variants, has emerged as the most frequently circulating variant in the United States in the past month, as stated by the Centers for Disease Control and Prevention (CDC). The CDC obtained this information from their data and referred to it as “the CDC.” The spike protein of FLiRT variations, including KP.2’s “parental” lineage JN.1, has three significant alterations that allow them to avoid being recognized by antibodies, according to findings from Johns Hopkins University.
Why FLiRT Variants Are More Infectious
Dr. Aaron Glatt, a representative of the Infectious Infections Society of America, has not observed any indicators of an increase in hospitalizations or infections due to FLiRT variants. This observation is based on the data he collects and his experiences with his own patients. He believes that the significance of these differences has diminished over time, possibly due to the immunity that many people already possess. Prior immunizations and exposure to diseases have contributed to this immunity.
Positive Trends in Hospitalizations
In recent weeks, hospitalizations due to COVID-19 have been decreasing, according to data compiled by the CDC. The number of patients testing positive for COVID-19 in emergency rooms has also remained relatively stable over the past month. This positive trend is observed by others as well and is a situation that I find myself in at the moment.
