Symptoms
The symptoms of Lyme disease can vary widely, depending on the stage of the infection. In early stage, children may experience flu-like symptoms such as fever, headache, fatigue, and muscle and joint pain. A characteristic bull's-eye rash, known as erythema migrans, may also develop at the site of the tick bite. If left untreated, the infection can progress to the later stages, which can cause more severe symptoms such as neurological problems, such as facial palsy, and arthritis.
Causes
Lyme disease is caused by the Borrelia burgdorferi bacteria, which is transmitted to humans through the bite of an infected black-legged tick. Ticks become infected with the bacteria when they feed on infected animals, such as deer, mice, and birds. Children are at higher risk of infection if they live or play in areas where ticks are common, such as wooded or grassy areas.
