Berlin reports three Vibrio infections, one fatal, linked to warm sea water FAST-MOVING
Berlin's health authorities recorded three Vibrio infections in 2026, one of which resulted in death. All three patients were over 75 years old and had pre‑existing conditions such as diabetes, liver or heart disease. Two of the cases are believed to have arisen from wound or skin contact with sea or brackish water in Mecklenburg‑Vorpommern.
The Berliner Landesamt für Gesundheit und Soziales (Lageso) notes that the early 2026 season is likely driven by higher coastal‑water temperatures, as Vibrio bacteria multiply rapidly when surface water exceeds 20 °C. The Robert Koch‑Institut (RKI) confirms this temperature threshold. Health agencies, including the Bundesinstitut für Risikobewertung (BfR), advise people with open wounds to avoid bathing in the sea when water temperatures are above this level, because open wounds increase the risk of severe Vibrio infection.
