What are vector-borne diseases?

Almost everyone has been bitten by a mosquito, tick, or flea. Vectors are mosquitoes, ticks, and fleas that spread pathogens. A person who gets bitten by a vector and gets sick has a vector-borne disease. Some vector-borne diseases, like plague, have been around for thousands of years. Others, like Heartland virus disease and Bourbon virus disease, have been discovered recently.

• Everyone can protect themselves from mosquito, tick, and flea bites.
• Nootkatone, a new active ingredient from nature, can be developed into insecticides and insect repellents.
