Geography

What is the Lyme disease threat in your area?

Since Lyme disease was discovered in humans in 1975 and in dogs in 1984, the disease in both humans and dogs has been spreading geographically. Human Lyme disease has been found in all 48 contiguous states.1

What area do you live in?

Where you live can help you determine the level of risk for your dog.

Geographic Area Disease Threat Know the Facts
Red Zone An endemic area - Most dogs are at risk, and the threat is near-constant and pervasive - Lyme disease remains endemic in the Northeast and North-Central United States
- Nearly 75 percent of unvaccinated dogs in this area will eventually test positive, and each year some will develop Lyme disease3
Orange Zone Many dogs at risk, and the threat is present to varying degrees - From 2005 to 2010, human Lyme disease cases doubled or almost doubled in North Dakota, Indiana, Wisconsin, Nebraska, and West Virginia1
- Human cases have increased sharply in Minnesota, Virginia, Oregon and Illinois1
- Dogs in these areas can be sentinels for Lyme disease in people
Yellow Zone Some dogs at risk, and the threat is present in some areas - Human Lyme disease has been found in all 48 contiguous states1
- Dogs are at risk in any area where human Lyme disease has been diagnosed
- Dogs in these areas can be sentinels for Lyme disease in people
- Clinical signs can be confused with many other diseases
- If your dog travels to a Red or Orange zone area, the risk increases significantly
