Los Angeles County health officials identified seven cases of flea-borne typhus within the Wilshire Center neighborhood. Six of the seven individuals affected by the bacterial infection required hospitalization, though all patients have since recovered.
Why it matters
Flea-borne typhus is a bacterial infection transmitted to humans by fleas found on local wildlife and pets, posing a persistent health risk in urban environments. Monitoring these local outbreaks is critical for residents to understand exposure risks associated with neighborhood wildlife and household animals.
The seven recent cases in Wilshire Center contribute to a county-wide total of 109 infections reported in 2026. This figure sits below the 220 cases documented in 2025 and the 187 cases reported in 2024.

The local agency responsible for monitoring infectious disease outbreaks and providing health guidance to residents.
The details
The disease spreads when humans come into contact with infected fleas that typically live on rats, opossums, and domestic cats. Once the flea bites a human or leaves infected waste near a bite, the bacteria can enter the bloodstream. Doctors treat the resulting infection with antibiotics, as the condition does not transmit from person to person.

The Home Front
This outbreak reflects an established regional trend of increasing flea-borne typhus infections seen across the county since 2010. While recent annual counts have fluctuated, the sustained presence of the disease highlights ongoing public health challenges in local residential areas.
Residents should focus on managing wildlife access to their property and ensuring household pets receive regular flea preventative treatments. If you notice signs of illness, consult a medical professional immediately as the disease is treated with antibiotics.
The takeaway
While flea-borne typhus is a serious bacterial infection, it is manageable with medical intervention if caught early. Keep your home safe by using veterinarian-approved flea control on all cats and dogs to minimize the risk of bringing infected pests indoors.
