 Lyme disease is progressive and multiple organ systems may be involved.

Borrelia burgdorferi is closely related to the spirochete that causes syphilis, and like syphilis, there are three defined clinical stages.
  

Stage 1
  Acute illness (weeks)		 Tick bite, fever, erythematous papule, erythema chronica migrans, lymphadentitis
     
Stage 2
  Dissemination 
   (weeks to months)		 CNS: Meningoencephalitis, cranial neuritis

Cardiac: Heart block, pericarditis, myocarditis
     
Stage 3
  Late chronic form		 Destructive chronic arthritis
Acrodermatitis atrophicans
Neuropathy
  
As with syphilis, the initial lesion, erythema chronic migrans is transitory, and will likely disappear on its own in a few weeks.
