Why the Flu Wave Claims So Many Victims Every Year

The real flu hits Austria every winter – usually from mid-January to the end of March. Between five and ten percent of adults and up to 20 percent of children fall ill in strong seasons.

According to virologist Monika Redlberger-Fritz from MedUni Vienna, around 1,300 people die annually on average from the consequences of influenza. Heart attacks or strokes often occur in connection with the infection.

Warning Against Underestimating the "Flu"

In the 2022/23 season, there were particularly many cases: Approximately 700,000 illnesses and 4,000 influenza-associated deaths were recorded. Redlberger-Fritz: "Influenza strikes back twice as hard after breaks."

A French couple described how severe the illness can be. The woman, previously healthy, developed life-threatening complications after an infection. She was in a coma for about six months, spent almost a year in the hospital, and lost parts of her legs and fingers. "Youth does not protect," warned the affected individuals, who have since been raising awareness.

Why the Vaccination is Needed Anew Every Year

A central problem is the rapid change of the viruses. "It's like a game of telephone in nature," explained Redlberger-Fritz. Because the immune system no longer sufficiently recognizes altered variants, the vaccination must be adjusted annually. According to experts, it does not always prevent illness, but it can mitigate severe courses.

Elderly and Pre-existing Conditions Particularly at Risk

High risks exist especially for people over 70 years old or with chronic diseases such as COPD or asthma. If a bacterial infection develops additionally, months-long intensive stays are not uncommon. Many affected individuals cannot return to their accustomed lives afterward.

"This is an enormous burden on the entire system," said internist Matthias Vossen from MedUni Vienna. In addition to high patient numbers, numerous sick leaves among medical staff are also a consequence. His appeal: "We would be very grateful if you get vaccinated."
