Tick bites and concerns about Lyme disease are increasing, especially during warmer months. In this episode of Health Matters, host Courtney Allison speaks with Dr. Laura Kirkman and Dr. Karen Acker of NewYork-Presbyterian, Weill Cornell Medicine, and NewYork-Presbyterian Komansky Children’s Hospital of Children’s Hospital of New York about what people should know about ticks and Lyme disease.

Dr. Kirkman explains the types of ticks found in the U.S., where they live, and how they attach to the body. She emphasizes that not every tick bite leads to Lyme disease—it depends on the tick species, whether it carries the bacteria, and how long it remains attached.

Dr. Acker explains how Lyme disease is transmitted and outlines the stages of infection, including early symptoms such as the characteristic bullseye rash, fever, and fatigue, as well as less common complications involving the nervous system, heart, or joints.

The conversation also covers how Lyme disease is diagnosed and treated, including when testing is necessary and when a preventive dose of antibiotics may be recommended after a tick bite.

Finally, the doctors share practical strategies to prevent tick bites—from tick checks and proper clothing to repellents and safe tick removal—and discuss emerging concerns like lone star ticks and alpha-gal syndrome. Their key message: with awareness and simple precautions, you can significantly reduce your risk.
