Pico-Union flea-borne typhus outbreak prompts LA health warning
Five Pico-Union residents have contracted flea-borne typhus this year; all were hospitalized but recovered, as LA County Public Health investigates a broader county-wide rise (2025 saw a record 220 cases with high hospitalization rates). Typhus is caused by Rickettsia typhi and spread by fleas carried by pests like rats, stray cats, and opossums around homes; prevention focuses on year-round flea control for pets, avoiding stray/wildlife around the home, and keeping yards clean.
