A Austria has recorded a sharp increase in flu infections at the start of 2026, with health officials warning that the Christmas holiday period failed to slow the spread of illness.
Data from the Austrian Health Insurance Fund (ÖGK) show that sick leave due to influenza is now four times higher than a year ago, driven mainly by rapidly circulating flu viruses. Overall sick leave levels remain unusually high for this time of year.
“The number of people on sick leave in Austria continues to be at a high level,” said Dr Andreas Krauter, chief medical officer of the ÖGK.
In the first week of January alone, the ÖGK recorded 41,154 cases of flu-like infections and 4,734 confirmed influenza cases. By comparison, at the end of last year just over 4,000 people were absent from work due to influenza.
Health authorities have also identified a new hotspot. While Vienna recorded the highest number of influenza cases in 2025, the province of Styria has now overtaken the capital, reporting 915 cases, compared with 899 in Vienna.
Officials are urging the public to take precautions. “We strongly recommend the free flu vaccination, as it offers the most effective protection against severe illness,” Krauter said. He also stressed the importance of hand hygiene, staying home when symptomatic, and regularly ventilating indoor spaces.
Virologist Monika Redlberger-Fritz from the Medical University of Vienna warned that infections are likely to rise further as schools reopen. Although testing submissions declined over the holidays, laboratories have already recorded an upswing. According to Austria’s national influenza reference laboratory, around half of all current sentinel samples are positive for influenza A.
Health authorities advise people to seek vaccination advice from their family doctors or through official ÖGK channels.
