Vector Information

The Lone Star Tick is an easily identifiable tick due to the white dot or 'lone star' spot on the back of a dark brown colored tick. These ticks are found in the southeastern and eastern United States. The lone star tick is a very aggressive tick capable of spreading disease to humans. The nymph and adult females most frequently bite humans and transmit disease. These ticks are able to transmit Ehrlichia chaffeensis and Ehrlichia ewingii (both cause human ehrlichiosis), tularemia, and STARI.

*Disease transmission varies locally. This map depicts where vectors can be found geographically and provides information about diseases these vectors might carry. Vectors might be present in a state or locality, however, and not be carriers of any particular disease. In addition, identified vectors may have a presence in a state, but may not be found throughout that state.
