The cause of tick-borne relapsing fever across central Africa was named Spirillum duttoni.

It is only when Ann becomes deathly ill with tick-borne relapsing fever that her mother begins to brighten.

Tick-borne relapsing fever, transmitted by either ticks or lice, has been reported from the plateau regions in central Mexico.

It is a known vector of Borrelia hermsii, a spirochete responsible for tick-borne relapsing fever in humans.

Relapsing fever (Tick-borne relapsing fever, different from Lyme disease due to different Borrelia species and ticks)

The reaction is also seen in other diseases caused by spirochetes, such as borreliosis (Lyme disease and tick-borne relapsing fever) and leptospirosis, and in Q fever.

Tick-borne relapsing fever is found primarily in Africa, Spain, Saudi Arabia, Asia in and certain areas of Canada and the western United States.

It resembles bacterial sepsis and can occur after initiation of antibacterials, such as penicillin or tetracycline, for the treatment of louse-borne relapsing fever (80-90% of patients) and in tick-borne relapsing fever (30-40%).

In Western Africa and sub-Saharan Africa, tick-borne relapsing fever has been recognized for over a century, since it was first isolated by the British physicians Joseph Everett Dutton and John Lancelot Todd in 1905.

Under the "Health Risks Abroad" section, she discussed specific occurrences of grim infections "absent from most countries of the world": plague, Rocky Mountain spotted fever, Colorado tick fever, tick-borne relapsing fever, Lyme disease and histoplasmosis.

Some parasitic forms affect humans and other mammals, causing damage by their feeding, and can even be vectors of diseases such as scrub typhus, rickettsialpox, Lyme disease, Q fever, Colorado tick fever, tularemia, tick-borne relapsing fever, babesiosis, ehrlichiosis and tick-borne meningoencephalitis.

In 1939 Academician E.N.Pavlovsky announced his "doctrine of nidality", so called by Soviet biologists People can acquire zoonoses and insect-borne diseases when they occupy at certain times of the year natural habitat of a certain pathogen (plague, tularemia, leptospirosis, arboviruses, tick-borne relapsing fever.

Under Pavlovsky's direction, they organized numerous complex expeditions to the Central Asia, Transcaucasus, Crimea, Russian Far East and other regions of the Soviet Union to study endemic parasitic and transmissible diseases (tick-borne relapsing fever, tick-borne encephalitis, Pappataci fever, leishmaniasis etc.).
