Key Points:
- A significant outbreak of flea-borne typhus is being investigated in the Pico-Union neighborhood of Los Angeles, with five hospitalized cases identified so far this year, all of whom have recovered.
- Flea-borne typhus, caused by the Rickettsia typhi bacteria spread through infected flea feces, has seen a rising trend in Los Angeles County, with 220 cases reported in 2025, the highest ever recorded.
- The disease is severe, with nearly 90% of diagnosed cases in 2025 requiring hospitalization, and affects a wide age range from 1 to 85 years old.
- The LA County Department of Public Health emphasizes prevention through flea control on pets, avoiding stray animals, and maintaining clean yards, as fleas commonly reside on rats, free-roaming cats, and opossums.
- Symptoms include fever, headache, rash, and body aches, and early antibiotic treatment is effective; the disease is not contagious between people but often contracted at home via infected fleas carried indoors by animals.
