Chatham County Tick Season Begins Soon

Tick Borne Illnesses

There are many infections that are transmitted by ticks. Once the weather is warm, they emerge and can become a source of infection for Chatham County residents. The most common tick borne illnesses in North Carolina are Rocky Mountain Spotted Fever, Ehrlichiosis, and STARI. There are also a few cases of Lyme disease each year. The following are all the major tick related diseases:

  • Anaplasmosis is transmitted to humans by tick bites primarily from the blacklegged tick (Ixodes scapularis) in the northeastern and upper midwestern U.S. and the western blacklegged tick (Ixodes pacificus) along the Pacific coast.
  • Babesiosis is transmitted by the blacklegged tick (Ixodes scapularis) and is found primarily in the eastern U.S.
  • Ehrlichiosis is transmitted to humans by the lone star tick (Ambylomma americanum), found primarily in the southcentral and eastern U.S.
  • Lyme disease is transmitted by the blacklegged tick (Ixodes scapularis) in the northeastern U.S. and upper Midwestern U.S. and the western blacklegged tick (Ixodes pacificus) along the Pacific coast.
  • Rickettsia parkeri Rickettsiosis is transmitted to humans by the Gulf Coast tick (Amblyomma maculatum).
  • Rocky Mountain Spotted Fever (RMSF) is transmitted by the American dog tick (Dermacentor variabilis), Rocky Mountain wood tick (Dermacentor andersoni), and the brown dog tick (Rhipicephalus sangunineus) in the U.S. The brown dog tick and other tick species are associated with RMSF in Central and South America.
  • STARI (Southern Tick-Associated Rash Illness) is transmitted via bites from the lone star tick (Ambylomma americanum), found in the southeastern and eastern U.S.
  • Tickborne relapsing fever (TBRF) is transmitted to humans through the bite of infected soft ticks. TBRF has been reported in 15 states: Arizona, California, Colorado, Idaho, Kansas, Montana, Nevada, New Mexico, Ohio, Oklahoma, Oregon, Texas, Utah, Washington, and Wyoming and is associated with sleeping in rustic cabins and vacation homes.
  • Tularemia is transmitted to humans by the dog tick (Dermacentor variabilis), the wood tick (Dermacentor andersoni), and the lone star tick (Amblyomma americanum). Tularemia occurs throughout the U.S.
  • 364D Rickettsiosis (Rickettsia phillipi, proposed) is transmitted to humans by the Pacific Coast tick (Dermacentor occidentalis ticks). This is a new disease that has been found in California.

Help Prevent Ticks in Your Yard

Here are some simple landscaping techniques that can help reduce tick populations:

  • Remove leaf litter.
  • Clear tall grasses and brush around homes and at the edge of lawns.
  • Place a 3-ft wide barrier of wood chips or gravel between lawns and wooded areas to restrict tick migration into recreational areas.
  • Mow the lawn frequently.
  • Stack wood neatly and in a dry area (discourages rodents).
  • Keep playground equipment, decks, and patios away from yard edges and trees.
  • Discourage unwelcome animals (such as deer, raccoons, and stray dogs) from entering your yard by constructing fences.
  • Remove old furniture, mattresses, or trash from the yard that may give ticks a place to hide.

You can also do some things to reduce the chance you are bitten by a tick:

  • Use repellent that contains 20 percent or more DEET, picaridin, or IR3535 on exposed skin for protection that lasts several hours. Always follow product instructions. Parents should apply this product to their children, avoiding hands, eyes, and mouth.
  • Use products that contain permethrin on clothing. Treat clothing and gear, such as boots, pants, socks and tents with products containing 0.5% permethrin. It remains protective through several washings. Pre-treated clothing is available and may be protective longer.
