harsh!
must be ELISA to detect antibodiies to Borrelia
calf--tick bite--rash--erythema chronicum migrans
CNS sympt typical of borrelia

bt wats abt homosexuality here....n there is no history of rash in the question

[ArchivalUser]

homo ..concentric ring rash .presumed viral illness, I will go for PCR.

senility, there is nothing in patient history to take to tick bite and Lyme

that might be to distract u!
u did mention about rash!

[ArchivalUser]

agreed okt3!
but rash only on left calf?
typical of bite than a viral rash which might be more generalized
