Greece is experiencing a significant rise in Flu K cases, a mutated subvariant of influenza A, which has caused concern among health authorities amid the winter season. The outbreak comes alongside a broader wave of respiratory infections that have intensified over the holidays.
Professor Theodora Psaltopoulou, an epidemiology expert at the National and Kapodistrian University of Athens, highlighted the contagious nature of Flu K. She noted that the strain has put health systems under pressure in parts of Europe, such as the United Kingdom, and in New York, where thousands of cases and several deaths—including among children—have been reported.
Vaccine Effectiveness
Authorities emphasize that the current flu vaccine remains effective, particularly against severe disease. According to the latest data from the European Centre for Disease Prevention and Control (ECDC), the vaccine provides over 55% protection. Vaccination continues to be the primary tool to reduce the risk of severe illness from Flu K and other respiratory viruses.
Preventive Measures
Health officials recommend three key measures to protect against infection:
- Vaccination: Available for free, especially recommended for those over 60, children under five, and individuals aged 5–59 with underlying health conditions.
- Mask Use: Advised for vulnerable populations in crowded indoor settings.
- Early Medical Consultation: Those showing symptoms of respiratory infection, including children, should seek prompt medical advice. Early treatment with antiviral medication can significantly reduce the severity of the illness.
Duration of the Outbreak
Professor Psaltopoulou expects the surge to continue through the first two months of 2026, with cases likely persisting until February. She stressed that vaccination is still valuable even amid the ongoing outbreak, providing crucial protection against severe illness.
