Relapsing fever

Alternative Names:

Tick-borne relapsing fever, Louse-borne relapsing fever
Treatment:

The mainstay of treatment is antibiotics -- primarily tetracycline, doxycycline, or penicillin.


Expectations (prognosis):


The mortality (death) rate for untreated louse-borne relapsing fever ranges from 10-70% and from 4-10% in tick-borne relapsing fever. With early treatment, the mortality rate is reduced to 2-5%. Individuals with coma, myocarditis, liver dysfunction, and pneumonia are at higher risk of death.


Complications:
  • neurologic complications: seizures, weakness, facial droop, meningitis, coma
  • myocarditis -- may lead to arrhythmias
  • pneumonia
  • liver dysfunction
  • diffuse bleeding
  • Jarisch - Herxheimer's reaction during antibiotic therapy may be fatal in some cases

Calling your health care provider:

Notify your medical provider if you are a returning traveler and you develop fever -- there are many different possible infections that will need to be investigated in a timely manner.
