"Flea-borne typhus can cause serious illness, but it is preventable with simple steps. With cases at an all-time high and most requiring hospitalization, it's critical that people take simple steps now."
"The bacteria is spread when infected fleas bite a person. As these fleas bite, they defecate, and when a person scratches the bite, flea feces can enter the bloodstream."
Los Angeles County reported 220 flea-borne typhus cases in 2025, the highest on record. California had a total of 277 cases, marking a significant increase from previous years. Typhus is caused by Rickettsia typhi bacteria, leading to symptoms like fever and a petechial rash. The disease spreads through infected flea bites. Health officials emphasize the importance of preventive measures, including flea control for pets and avoiding contact with stray animals, to mitigate the risk of serious illness.
