Lyme Disease Rash


Picture of Lyme disease "bull's-eye" rash

One symptom of Lyme disease is a red rash (called erythema migrans) that looks like a bull's-eye. About half the people infected with Lyme disease develop the rash within 1 to 4 weeks. It occurs at the site of the tick bite and usually gets bigger over time.
