Overview
- Provisional 2025 data list 693 confirmed FSME cases plus about 100 suspected, putting the year on track to top the previous high of 704 in 2020 and the 695 confirmed in 2024.
- Specialists warn that official tallies capture only a fraction of infections, with registered cases representing roughly 10 percent of actual numbers.
- Researchers now regard all of Germany as at risk, with about 80 to 85 percent of reported cases still concentrated in Bavaria and Baden‑Württemberg and increases seen nationwide.
- Milder winters linked to climate warming keep ticks active year‑round and enable spread into cooler northern areas and higher elevations.
- A recent cold, snowy winter is expected to have little effect on tick populations, and nearly all reported FSME patients lacked adequate vaccination, prompting renewed calls to get immunized.
