Julu 27, 2023 -NEW YORK (AP) — In 2022, doctors recorded the first confirmed case of tick-borne encephalitis virus acquired in the United Kingdom. It began with a bike ride. A 50-year-old man was mountain biking in the North Yorkshire Moors, a national park in England known for its vast expanses of woodland and purple heather. At some point on his ride, at least one black-legged tick burrowed into his skin. Five days later, the mountain biker developed symptoms commonly associated with a viral infection — fatigue, muscle pain, and fever.
At first, he seemed to be on the mend, but about a week later, he started to lose coordination. An MRI scan revealed he had developed encephalitis, or swelling of the brain. He had been infected with tick-borne encephalitis, or TBE, a potentially deadly disease that experts say is spreading into new regions due in large part to global warming.
