PMCID: PMC338140 Relapsing fever is a recurring febrile disease caused by several species of the spirochete Borrelia and transmitted by lice or ticks. Symptoms are recurrent febrile episodes with headache, myalgia, and vomiting lasting 3 to 5 days, separated by intervals of apparent recovery Relapsing fever is an acute infectious disease caused by spirochetes of the genus Borrelia and characterized by recurrent bouts of fever separated by relatively asymptomatic periods. 112, 113 Relapsing fever is divided into two epidemiologic types: epidemic, or louse-borne, and endemic, or tick-borne (Box 10-4)

Relapsing fever is an acute borrelial disease characterized by recurrent episodes of fever and spirochetemia separated by afebrile periods. Epidemic relapsing fever is caused by Borrelia recurrentis and is transmitted by lice. It is virtually unknown in the United States Relapsing fever is a febrile illness caused by infection with some spirochetes of the genus Borrelia . Clinical symptoms include recurrent febrile episodes with headache, myalgia, chills, and nausea Endemic relapsing fever is caused by Borreliae which normally live in their natural host rodents, or in other mammals which the vector takes feed. Human infection is an accidental event. Borrelia recurrentis causes epidemic relapsing fever. It was first observed by Obermeyer in the blood of patients during an epidemic in Berlin Louse-borne relapsing fever is caused by the spirochaete Borrelia recurrentis. Borrelia recurrentis, like other Borrelia species, has a linear chromosome of 1Mb and five or six plasmids that vary in size from 11 to 192kb. Borreliae are helical, 8 to 30 µm long and 0.2 to 0.5 µm in diameter, are motile and have 8 to 30 flagella

Relapsing fever, infectious disease characterized by recurring episodes of fever separated by periods of relative well-being and caused by spirochetes, or spiral-shaped bacteria, of the genus Borrelia. The spirochetes are transmitted from one person to another by lice (genus Pediculus) and from animals to humans by tick s (genus Ornithodoros) Tick-borne relapsing fever is caused by Borrelia species transmitted by the saliva of infected soft ticks. 1 Humans are incidental hosts, and exposure typically occurs in mud huts in developing countries. Cases have been reported occasionally in the United States, with exposure occurring at camp sites and cabins in the Rocky Mountains Relapsing fever is a recurring febrile disease transmitted to humans by ticks (endemic form) and by body lice (epidemic form). It is caused by several different Borrelia species Background. Relapsing fever is a bacterial infection caused by spirochetes of the genus Borrelia.

Relapsing fever is a vector-borne, spirochetal infection characterized by recurring febrile episodes of a remitting nature. It is caused by several species of Borrelia. Borrelia are loosely coiled spirochetes that easily stain with Wright or Giemsa stain, allowing diagnosis to be established by examination of the blood smear. They also can be grown on artificial media Louse-borne relapsing fever (LBRF) is a vector-borne disease caused by the spirochaete Borrelia recurrentis, a human-restricted pathogen transmitted by the body louse Pediculus humanus humanus..
