In the beginning I also thought its not lyme disease...cos usually we see that Target shaped lesion (Bull's eye) rash.But the severe headache after sometime indicates CNS involvement. Which happens in the second/third stage of Lyme disease.

Lets wait for the official answer.

Default Answer

Correct Answer: A
Explanation:
Lyme disease is a tick-borne inflammatory disorder caused by the spirochete Borrelia burgdorferi. Its clinical hallmark is an early expanding skin lesion, erythema migrans (EM; previously called erythema chronicum migrans), which may be followed weeks to months later by neurologic, cardiac, or joint abnormalities. Within days of onset of EM patients develop multiple annular secondary lesions. These lesions, from which spirochetes have been cultured, represent clear evidence of dissemination. They resemble EM itself but are generally smaller, migrate less, and lack indurated centers. Individual lesions may come and go, and their borders sometimes merge. Skin involvement is often accompanied by musculoskeletal flulike symptoms–malaise and fatigue, headache, fever and chills. myalgia, and arthralgia . Even without EM, this syndrome in summer, in an endemic area for Lyme disease, is grounds for treatment. The chief vector of both diseases is the deer tick, Ioxdes scapularis (I. dammini). Both diseases are caused by bacteria. The white-footed mouse is the principal reservoir host for these bacteria in nature. Early detection, disease identification, and treatment are critical to prevent long term complications caused by these diseases. Laboratory diagnostic tests are not always reliable. Antibiotic treatment of choice is doxycycline or tetracycline for 14 days for persons older than 8 years.
