Lyme disease is an infection caused by various Borrelia genus, like Borrelia burgdorferi, Borrelia afzelii, and others.
The Borrelia bacteria is a spirochete that's often spread via tick bites. The first symptom shown after the incubation period is usually the bullseye rash, but this is not always the case.
If detected early, antibiotics can be administered and the infection will cease. However, if left untreated, serious symptoms may arise, such as joint pain, sleep disturbance, and neurological problems.
The disease is the most common in summer months and early fall.
