MURINE TYPHUS AND OTHER FLEA-BORNE RICKETTSIOSES: HISTORY,
MOLECULAR EPIDEMIOLOGYAND PUBLIC HEALTH CONSEQUENCES

Murine typhus is a re-emerging rickettsial disease with a wide-prevalence, most typically in temperate to tropical seaboard
regions. The disease manifests as a febrile illness with an acute onset and mild to severe morbidity, including severe
encephalitis and fatalities. Its classic form is associated with a rat flea and rat cycle, although other ectoparasites and animal
species are involved in the circulation of the etiologic agent, Rickettsia typhi. The disease was first described in 1913 in Atlanta,
GA, and its distribution was progressively widened. Broad application of pesticides and rodenticides was thought to bring the
disease under control for several decades in the USA. Use of molecular approaches to ecological studies and clinical diagnosis
in the last 20 years revealed continued circulation of R. typhi in different endemic locales, but also provided evidence for at
least two other flea-borne rickettsial agents, Rickettsia felis and Rickettsia asemboensis; they are frequently found in fleas and
animals formerly thought to be less typical vectors and reservoirs of murine typhus. These findings raised significant concerns
and a need for reevaluation of approaches to diagnosis of flea-transmitted rickettsial diseases, better understanding of the
ecology and epidemiology of flea-borne rickettsial agents and reassessment of methods used for flea control.This presentation
will review the most recent findings related to these issues and discuss the public health implications of the presence of these
rickettsial pathogens in areas affected by malaria and dengue. Because these diseases can present with symptoms of many other
infections, it is important to include epidemiological considerations when treating patients with febrile illness of unknown
etiology.
