In-Depth Analysis
Flea-borne typhus is caused by the bacterium *Rickettsia typhi*. Fleas become infected by biting infected animals like rats, stray cats, and opossums. The disease spreads to humans when infected flea feces enter cuts, scrapes, or the eyes.
**Typhus Hot Spots:** While cases are reported county-wide, outbreaks in 2025 were localized in central Los Angeles, Santa Monica, and Willowbrook.
**Who is at Risk:** Everyone is at risk, but those living outdoors or in areas with rodent infestations face a higher risk. The ages of those infected in 2025 ranged from 1 to 85.
**How to Prepare:**
- **Protect Your Pets:** Use flea control products year-round.
- **Avoid Stray Animals:** Do not feed or pet stray animals.
- **Secure Your Property:** Ensure trash bins are closed, block entry points for wildlife, and avoid leaving pet food outside.
Typhus is treatable with antibiotics, particularly doxycycline. Early diagnosis is crucial to prevent severe illness and hospitalization. Symptoms, appearing 1-2 weeks after infection, include fever, headache, chills, body aches, and a rash.
