Leprosy revealed in red squirrels across British Isles
UK-based researchers have recently found the red squirrels across the British Isles carry the same bacteria which causes leprosy in humans. Scientists believe the endangered animals have been infected with the disfiguring disease for centuries, which causes lesions on their muzzles, ears and paws. However, scientists concluded the squirrels' leprosy infection poses little risk to humans today.
