Flu wave 2025: Exploded influenza infections in Berlin!
In the flu season 2024/25, influenza in Berlin and Brandenburg showed a significant increase in infections compared to the previous season. According to rbb24 , a total of 18,717 influenza infections were reported between the beginning of October 2024 and mid-May 2025. For comparison: In the 2023/2024 season, only 7,584 infections were registered. The highest number was recorded in the first weeks of 2025, which illustrates the concern for worrying.
The increase in infections is due to genetic changes in the flu viruses, which meant that many people came into contact with the current subtype for the first time. As a result, the immune system could not react optimally to the infections. In Berlin, more than 16,200 flu cases were documented, which corresponds to more than a doubling compared to the pre -season and at the same time represents the highest value since the introduction of the Infection Protection Act 25 years ago. Experts strongly recommend that they use the current flu protection vaccinations in autumn.

According to the Ärzteblatt are the dominant viruses in ARE influencing influenza A and B, while Covid-19 is currently not the main cause of respiratory diseases. The flu wave began in the first calendar week (KW) 2025, and the incidence of the Are fell in the following week.
In virological monitoring, about 30 % of the samples influenza A and B viruses were demonstrated. This trend is also evident in visits to the doctor, which are due to acute respiratory diseases and have increased in all age groups.
