What is Relapsing Fever?

Relapsing Fever has been recognized for centuries, historically linked to epidemics during wars and famines. The causative *Borrelia* spirochetes were first observed in patient blood by *Otto Obermeier* in 1868, distinguishing it from other febrile illnesses like typhus.

Symptoms

  • Sudden onset of high fever (often >104°F / 40°C)
  • Chills and severe headache
  • Muscle and joint aches (myalgia and arthralgia)
  • Nausea, vomiting, and abdominal pain
  • Cycles of fever followed by periods of remission (days to weeks), then relapses (usually milder but recurring)

Transmission

Relapsing Fever is primarily transmitted through vectors. *Louse-borne relapsing fever (LBRF)* spreads when infected body lice are crushed on the skin, and the bacteria enter through broken skin. *Tick-borne relapsing fever (TBRF)* is transmitted through the bite of infected soft-bodied *Ornithodoros* ticks, which typically feed at night.

Contagious Period: Varies by disease

Prevention

  • Avoid contact with ticks and lice; use insect repellents (e.g., DEET or permethrin-treated clothing) in endemic areas.
  • Inspect skin and clothing for ticks after outdoor activities and remove them promptly and correctly.
  • Maintain good personal hygiene and sanitation, especially in crowded conditions or where lice infestation is a risk.
  • Control rodent populations around homes, as they can be hosts for infected ticks.
