Originally Published 21 hours ago — by SBS Australia
A new flu strain called 'Super-K' or subclade-K, a drifted version of H3N2, is spreading unusually in Australia outside the typical flu season, potentially increasing healthcare pressure. While not more severe, it is more transmissible and slightly less responsive to vaccines, prompting updates to the 2026 flu vaccine. Experts recommend vaccination and preventive measures to reduce infection risk.
