Flea-Borne (Endemic) Typhus

Typhus refers to a group of infectious diseases that are caused by rickettsial organisms and result in an acute febrile illness. The principle diseases of this group are epidemic (or louse-borne) typhus, flea-borne (or endemic) typhus, and scrub typhus.

Flea-borne typhus (sometimes called murine typhus) is the only one of these diseases naturally occurring in LA County and is caused by two bacteria Rickettsia typhi and R. felis. Flea-borne typhus can spread to humans from bacteria found in infected fleas. Infection happens when the feces from infected fleas are rubbed into cuts or scrapes in the skin or rubbed into the eyes.

Symptoms can start within two weeks after contact with the infected flea and include high fever, headache, chills, and body aches. A rash can appear on the chest, back, arms, or legs. In rare cases, there may be swelling at the lining of the brain (meningitis) and heart valves (endocarditis). Fatalities are uncommon, occurring in less than 1% of cases. The disease is typically mild in young children. Typhus infection is not vaccine preventable, but can be treated with antibiotics.

REPORTING
Flea-borne typhus and other rickettsial infections are reportable in California. Reporting of cases guides the Los Angeles County Department of Public Health to target surveillance activities and health education. A standard Confidential Morbidity Report (CMR) can be used to file a report; the CMR may be faxed to the DPH Morbidity Unit at (888) 397-3778 or (213) 482-5508. You may also report cases by telephone during normal business hours from 8:00 a.m. to 5:00 p.m. to (888) 397-3993. For cases among residents of the cities of Long Beach or Pasadena, please contact their local health departments.
