Lyme disease is transmitted to humans by the bites of infected ticks of the genus Ixodes. Despite appropriate treatment, about 10 to 20% of people develop joint pains, memory problems, and tiredness for at least six months. Occasionally, people develop shooting pains or tingling in their arms and legs. Months to years later, repeated episodes of joint pain and swelling may occur. If untreated, symptoms may include loss of the ability to move one or both sides of the face, joint pains, severe headaches with neck stiffness, or heart palpitations, among others. Other early symptoms may include fever, headache, and tiredness. Approximately 70–80% of infected people develop a rash. The rash is typically neither itchy nor painful. The most common sign of infection is an expanding red rash, known as erythema migrans, that appears at the site of the tick bite about a week after it occurred. Lyme disease, also known as Lyme borreliosis, is a vector-borne disease caused by the Borrelia bacterium which is spread by ticks in the genus Ixodes.
