Orange County Reports 5th Case of Flea-Borne Typhus

A case of flea-borne typhus has been discovered near the intersection of Slater Avenue and Magnolia Street in Fountain Valley, prompting public health advisories in the area. According to Brian Brannon from Orange County Mosquito and Vector Control, the disease is primarily spread by the excrement of fleas, which enters the bloodstream when scratched. Orange County has seen five confirmed cases of flea-borne typhus this year, with instances in Fountain Valley, Santa Ana, Anaheim, and Garden Grove.

Brannon emphasized the importance of monitoring pets for fleas, as they can carry the disease. He specifically warned against interacting with feral cats and possums, known carriers of typhus. Symptoms of the disease include fever, rash, and severe headache, with some cases requiring hospitalization.

While typhus is not transmissible between people, precautions such as regular pet flea treatments, wearing insect repellent outdoors, and keeping a clean environment to deter animals are advised by OC Vector. Any sightings of dead animals should be reported to animal control.

Despite the severity of typhus, no deaths have been reported in Orange County. Residents are urged to take preventive measures and be vigilant in protecting against this potentially deadly disease. Stay informed and take proactive steps to safeguard against flea-borne illnesses.
