“Super flu” alert: Symptoms, duration, and what to watch for
Health experts are warning that a new wave of influenza—scientifically identified as Influenza A (H3N2) and widely referred to as the “super flu”—is expected to peak toward the end of January, amid a sharp rise in cases across Europe due to its high transmissibility.
Speaking to Greek state broadcaster ERT, Professor Theodora Psaltopoulou of the National and Kapodistrian University of Athens (EKPA) Medical School, an expert in Epidemiology and Preventive Medicine, said the outbreak is currently on an upward trajectory and urged the public to exercise heightened caution. She stressed that the seasonal flu vaccine remains a key tool both for prevention and for reducing the severity of illness.
A Highly Contagious Variant
According to Psaltopoulou, the variant—referred to as the “K strain”—is a mutated sub-lineage of Influenza A and appears to be significantly more contagious.
“Case numbers are rising sharply across Europe, placing considerable strain on healthcare systems,” she said. In the United States, more than 3,000 flu-related deaths have already been recorded this season, including eight children, she added.
Growing Pressure on the Health System
In Greece, the increasing number of cases is also putting pressure on the National Health System (ESY), with hospitals approaching capacity in some areas. Experts emphasize that early diagnosis and limiting close contacts are critical to controlling the spread.
Prevention and Protection Measures
Specialists underline that the annual flu vaccination remains the most effective form of protection. Even when administered later in the season, the vaccine can significantly reduce the risk of severe illness and death. In Greece, the flu vaccine is provided free of charge, with enhanced formulations for older adults and nasal spray vaccines for children also available.
Additional recommendations include:
- Regular and proper hand washing
- Adequate ventilation of indoor spaces
- Self-isolation when symptoms appear
- Mask use in crowded settings
For high-risk individuals, experts advise starting antiviral treatment early, as soon as symptoms develop, without waiting for test results.
“This year’s situation once again reminds us that influenza remains a serious public health threat,” Psaltopoulou noted, stressing that preventive measures—especially during periods of increased social activity—are crucial to protecting both vulnerable groups and the wider community.
