Symptoms vary from asymptomatic to flu-like illness, a characteristic rash, and in severe cases, nerve damage, heart problems, and long-term joint or neurological issues.
The disease is relatively uncommon, with around 1,000 confirmed cases annually in England and Wales, and was first identified in Lyme, Connecticut.
Transmission occurs exclusively via infected ticks, which are found in specific UK regions including the Lake District, New Forest, North York Moors, and Scottish Highlands.
Prevention involves avoiding tick-heavy areas and taking precautions like wearing protective clothing and using insect repellent, with treatment typically involving antibiotics if a bite occurs in a high-risk area.
