They are arachnids, not insects. There are hundreds of different kinds of ticks in the world. Many of them carry bacteria, viruses or other pathogens that cause disease in humans and/or animals. In the midwestern and eastern United States, Ixodes scapularis or deer tick is the primary vector of Lyme disease. On the West Coast, the spirochete is carried by Ixodes pacificus or western black-legged tick.
In the northeastern and north-central United States, the blacklegged tick (or deer tick, Ixodes scapularis) transmits Lyme disease. What are the symptoms of Lyme Disease? The Lyme disease bacterium can infect several parts of the body, producing different symptoms at different times. Not all patients with Lyme disease will have all symptoms, and many of the symptoms can occur with other diseases as well. The first sign of infection is usually a circular rash. This rash occurs in approximately 70-80% of infected persons and begins at the site of a tick bite after a delay of 3-30 days.
