The World Health Organization (WHO) has issued an alert due to the rapid and early spread of a new dominant influenza strain in Europe, named A(H3N2) subclade K. According to the organization, this winter season began four weeks earlier than usual, creating additional pressure on the healthcare systems of countries like the United Kingdom, Ireland, and Serbia. The new variant already accounts for up to 90% of confirmed cases in the European region, according to Noticias Argentinas news agency. Data from the UK indicate that the current vaccine significantly reduces the risk of serious complications, although it does not always prevent initial infection. Hans Henri P. Kluge, WHO Regional Director for Europe, stated that while the virus is causing a very high volume of infections, there is no scientific evidence to date that this strain causes a more severe illness than previous ones. Health authorities insist that vaccination remains the most important preventive measure, especially for: older adults and children, pregnant women, individuals with underlying medical conditions, and healthcare workers. The peak of the influenza season in the Northern Hemisphere is expected between late December and early January, so the population is advised to maintain hygiene measures and seek medical attention only in case of severe symptoms.
