What is the Flu K Variant?
The Influenza virus is constantly evolving, leading to the emergence of new variants. Recently, the K variant has been identified as actively circulating, particularly in France. Reports from Liberation indicate that while present, the variant is not currently causing widespread alarm. This suggests it’s not immediately more severe than other circulating strains, but ongoing monitoring is essential.
Influenza viruses are categorized into types (A, B, C, and D), with types A and B causing seasonal epidemics in humans. The ‘K’ designation likely refers to a specific genetic marker or antigenic drift within one of these types,differentiating it from previously circulating strains. These changes are why annual flu vaccines are necessary.
