 Flea-borne typhus resurges in Los Angeles, county reports record 220 cases

Flea-borne typhus, an old disease spread by fleas, is making a notable comeback in California, particularly in Los Angeles, where health officials are urging residents to stay vigilant. Last year, the Los Angeles County Department of Public Health documented more than 200 cases—the highest on record for the county—with patients ranging in age from 1 to 85. Roughly 90% of those infected required hospitalization, prompting officials to emphasize preventive measures such as regular flea control for pets.

Flea-borne typhus, also known as murine or endemic typhus, is caused by the bacteria Rickettsia typhi, a relative of the bacteria behind epidemic typhus, which is spread by body lice. Symptoms typically appear one to two weeks after infection and can include fever, headache, vomiting, and a distinctive rash. The bacteria naturally live in rats and other small mammals, with humans becoming infected when fleas transmit the bacteria through bites, contaminated feces, or dust. Though rare in the U.S. for decades thanks to sanitation improvements and antibiotics, the disease has surged recently, with preliminary statewide data showing record-high cases last year. Health officials warn that typhus spreads more easily among vulnerable populations, including people experiencing homelessness or living in rodent-infested areas, and urge residents to take steps to limit exposure, including controlling fleas on pets, avoiding stray animals, and keeping wildlife away from homes.
