[Tick-borne relapsing fever morbidity in Namangan].

The authors discuss the incidence of tick-borne relapsing fever in the town of Namangan (Uzbekistan) in 1976-1991 and the possible sites of human infection; the agent, Ornithodoros papillipes, has never been detected over this period. Analysis of many-year and seasonal time course of the disease incidence, of the age of the patients and their residence, characterization of the possible habitats of the agents, and comparison of the situation in the town with that in the adjacent rural territories permit a suggestion that the majority of the patients were infected at home.
