Infectious typhus, fueled by homeless, reaches epidemic levels in southern California

Typhus, or typhus fever is an infectious disease spread by fleas. Symptoms can include high fever, headache, chills, and body aches, rashes and in some rare cases, meningitis and even death.

KMI 640AM reports, Oct. 9, 2018, that health officials in Southern California are warning residents to be aware of a typhus outbreak that’s reached ‘epidemic’ levels in some areas.

University of Southern California Associate Professor of Medicine Neha Nanda says “what’s different this year is there’s this clustering of this disease in downtown L.A., so hence the concern of this being an epidemic.”

Long Beach has also seen a high number of infections with 12 cases so far in 2018.

Officially, the source of the outbreak is said to be from fleas found on pets and wild animals, but some health experts believe it’s being fueled by the homeless crisis.

A press release from the Pasadena Public Health Department says:

The Pasadena Public Health Department (PPHD) is reporting epidemic levels of typhus fever this year. Typhus fever is a disease spread to humans by infected fleas. In 2018, 20 Pasadena residents have been confirmed to have typhus fever, well above the expected one to five cases per year.

Flea-borne typhus, also known as murine or endemic typhus, is a disease carried by fleas infected with bacteria (Rickettsia typhi or Rickettsia felis)….

Locally, the primary animals known to carry infected fleas include feral cats and opossums. People with significant exposure to these animals are at risk of acquiring flea-borne typhus. Pet dogs and cats that are allowed outside are more likely to come in contact with infected fleas and could spread the disease to humans. Although pets and animals do not get sick from typhus, the disease can cause high fever, chills, headache and rash in people. Typhus can be treated with antibiotics.

“Typhus fever is a disease that can cause serious complications requiring lengthy hospitalization, and rarely, death,” said Dr. Ying-Ying Goh, Pasadena Health Officer. “All residents should to take steps to prevent fleas in and around the home.”

There are simple precautions to prevent the spread of typhus fever disease:

  • Maintain the yard free of debris and trim overgrown vegetation to prevent harborage of wild animals like feral cats and opossums
  • Do not leave pet food outdoors
  • Do not provide food or water for wild animals
  • Keep garbage containers tightly covered
  • Seal all openings and crawl spaces under the home
  • Routinely treat pet dogs and cats with flea control medication

Local healthcare providers are required to report any Pasadena residents with a suspected or confirmed typhus diagnosis within one working day to PPHD at (626) 744-6089 Monday to Friday 8 AM-5 PM, or (626) 744-6043 after hours. Diagnosis requires a high degree of clinical suspicion since flea-borne typhus typically presents as a non-specific febrile illness and early diagnostic tests are unreliable.
