Retired Scientist's Ordeal: Tick-Borne Encephalitis Diagnosis

In August 2025, retired scientist Bill Lankford, 62, fell critically ill after completing a demanding 50km swim-run across Scandinavia. He initially experienced fatigue and muscle ache, which he attributed to post-event exhaustion and travel. However, his symptoms, including intense headaches and flu-like conditions, resurfaced with greater severity.

Lankford's condition rapidly deteriorated, presenting with excruciating headaches, balance difficulties, and sensitivity to light. After visiting his GP and being initially treated for Lyme disease, his symptoms worsened dramatically, compelling him to seek emergency hospital care. Doctors conducted numerous tests, including cerebrospinal fluid sampling.

In September 2025, at age 61, Lankford was diagnosed with tick-borne encephalitis (TBE), a rare viral infection transmitted by tick bites. The illness caused significant neurological impairment, including memory problems and chronic fatigue, necessitating a lengthy recovery period.

Nine months post-diagnosis, Lankford has made notable progress, gradually rebuilding his physical strength. He recently completed a shorter, 22km swim-run event, a testament to his recovery, though he acknowledges long-distance events are no longer feasible. He strongly advises active individuals in tick-prone areas to consider TBE vaccination.
