Lyme disease cases are on the rise in the United States. While the nature of Lyme disease symptoms makes it difficult to know exactly how many people get Lyme disease each year, the CDC reported that there were 23,453 cases in 2019. Lyme disease frequency maps show a shocking concentration of cases in the Northeast. This infographic by the CEUFast.com research team can help to spread awareness by highlighting the counties with the most Lyme disease cases recently and over time.
Lyme disease is a tick-borne illness that is caused by the bacterium Borrelia burgdorferi. Lyme disease is transmitted to humans through the bite of ticks that are infected with this bacteria. The chances of getting Lyme disease from a tick bite range from zero to 50 percent, depending on three key factors: the species of tick, where the tick came from, and how long it was attached. Lyme disease can also be transmitted through ticks to other mammals. Animals that can get Lyme disease include dogs, horses, cattle, white-tailed deer, mice, chipmunks, squirrels, and raccoons. Dogs that hike, spend time in the yard, or even just walk around the neighborhood can pick up disease-carrying ticks, which is why it is important to take preventative measures to protect our loyal companions. The American Veterinary Medical Association provides a comprehensive guide on how to prevent Lyme disease in dogs.

A key step to preventing Lyme disease is to know if you are in a location that requires extra vigilance due to large tick populations. The states with the most Lyme disease cases include Pennsylvania, New York, New Jersey, Maine, Wisconsin, New Hampshire, Minnesota, Maryland, Connecticut, Virginia, and Vermont. While statewide data is helpful, knowing the counties with the most Lyme disease cases can promote awareness, caution, and prevention.
