Los Angeles County health officials are investigating a localized outbreak of flea-borne typhus in the Wilshire Center neighborhood that hospitalized six people, marking the second major cluster of the bacterial disease in the area this year. The Los Angeles County Department of Public Health announced the findings this week, noting that 109 cases have been reported across the county so far this year.
Understanding Flea-Borne Typhus Vectors and Transmission
Flea-borne typhus, also called murine typhus, is an acute febrile bacterial infection caused by Rickettsia typhi. According to health officials, rodents serve as a primary animal host, but free-roaming cats, opossums, and other small mammals also carry the bloodsucking insects. People typically contract the bacteria when infected fleas defecate near bite wounds. Individuals can also breathe in infected flea dust or accidentally rub the material into their eyes. The Los Angeles County Department of Public Health emphasizes that the infection does not spread from person to person.
Recent Outbreaks Across Los Angeles County Neighborhoods
The Wilshire Center cluster accounts for at least seven identified cases, with six patients requiring hospitalization. All impacted individuals have since recovered, according to the health department. This follows a separate outbreak reported in late July in the Pico-Union neighborhood, which sickened and hospitalized five people who have also recovered. Outside of these specific neighborhood clusters, health authorities report cases scattered throughout the region. Officials note that typhus cases typically peak during late summer and fall, meaning counts could rise further.
Did You Know?
While people experiencing homelessness face higher risks due to increased exposure to fleas and host animals, the Los Angeles County Department of Public Health stresses that anyone can catch the infection. Last year, documented cases spanned all age groups from 1 to 85 across diverse housing and socioeconomic backgrounds.
Practical Steps for Flea and Typhus Prevention
To minimize infection risks, Los Angeles County Health Officer Muntu Davis advises residents to prevent exposure to fleas on free-roaming animals and wildlife. Recommended precautions include:
- Applying flea control products year-round on pets, particularly if they roam freely outdoors.
- Avoiding feeding or touching wild animals, and refraining from leaving food outside that attracts wildlife.
- Maintaining yards free of debris and keeping household trash securely contained.
- Sealing any structural openings where rodents or wild mammals might enter homes.
“Simple steps can prevent serious illness,” Davis said in a statement released Tuesday.
