The resurgence of flea-borne typhus, a highly contagious bacterial illness once thought to be a relic of the past, has sparked concern in Los Angeles County. With 90% of infected individuals requiring hospitalization, the outbreak highlights the ease with which the disease can go unnoticed and the importance of proactive prevention measures.

Why it matters

The rise in flea-borne typhus cases, which can be transmitted through flea feces entering the body, underscores the ongoing threat of infectious diseases that were once considered eradicated. The outbreak serves as a stark reminder of the need for vigilance, proactive prevention, and public health awareness to combat this 'Victorian disease' in the modern era.

The details

Flea-borne typhus is transmitted through flea feces entering the body through cuts or scrapes, or even by rubbing the eyes after contact with infected fleas. Pets can unknowingly bring infected fleas into the home, acting as a bridge between wildlife and humans. Symptoms can take up to two weeks to appear, often starting with fever, chills, body aches, and a rash, and in more severe cases, coughing, gastrointestinal issues, and neurological symptoms such as confusion.

  • In 2025, Texas reported a surge in flea-borne typhus cases, indicating a broader trend.
  • The current outbreak in Los Angeles County has been ongoing since early 2026.
