Lyme disease signs include which of the following presentations?

• A. Rash
• B. Target bull's eye pattern
• C. Painful swelling of joints
• D. Headache

Answer: (B)

The key sign is an expanding erythema migrans rash with central clearing, which creates a bull's-eye (target) appearance. This distinctive rash is the classic early indicator of Lyme disease and helps differentiate it from other conditions. While a rash can occur in many illnesses, and headaches or joint pain can accompany Lyme, these are less specific and joint swelling usually appears later. So the bull's-eye rash best identifies Lyme disease among the options.
