As November draws to a close, health experts around the world are closely monitoring the start of the 2025 flu season, focusing on subclade K, a new variant of the H3N2 influenza virus.
First identified in the summer, this variant has already sparked outbreaks in Canada, Japan, and the UK. While the U.S. has yet to see a major wave, officials warn that cases could emerge in the coming weeks.
Health experts note that subclade K carries genetic mutations that may influence how the virus spreads and how well current vaccines work. Ongoing studies aim to clarify its full impact.
With international travel climbing ahead of year-end holidays, travellers and digital nomads should stay informed: practice good hygiene, consider masks in crowded settings, and follow local health advisories.
