Can Fleas Transmit Diseases to Humans
Yes, fleas can carry and transmit several diseases to humans. They become infected when they feed on diseased animals and can pass pathogens through bites or contact with flea dirt. Common diseases include plague, murine typhus, and cat scratch disease.
Common Flea-Borne Diseases and Symptoms
Plague causes fever, chills, and swollen lymph nodes. Murine typhus leads to headache, fever, and rash. Cat scratch disease may cause swollen lymph nodes and fatigue. Symptoms often appear days to weeks after a flea bite.
How to Reduce Flea Disease Risk
Protect yourself by treating pets with flea control products, vacuuming floors regularly, and washing bedding frequently. Wear long sleeves and use insect repellent in areas with high flea activity. If you develop symptoms after flea bites, consult a healthcare provider promptly.
