Erythema Migrans is a skin condition characterized by a distinctive rash that often appears as a circular, red area with a lighter center. It is commonly associated with Lyme disease, which is caused by the bacterium Borrelia burgdorferi and transmitted through the bite of infected ticks. The rash typically develops within days to weeks after the bite and can expand over time. While Erythema Migrans is not contagious, it is an important indicator of Lyme disease. Early detection and treatment with antibiotics can prevent more severe symptoms, such as joint pain and neurological issues. If you notice a rash resembling Erythema Migrans, it is essential to seek medical advice promptly.
