What Diseases Can Be Transmitted by Ticks?

Ticks are mostly found in grassland areas, but when they feed, they can transmit a variety of diseases.

Most people who engage with grassland areas know they should check themselves for ticks once they are out of the area. They need to do a thorough check of their entire body, including the armpit and groin region, which are known as major skin folds. These are the areas where ticks generally like to migrate to once they get onto the human body.

Outside of the transmission of diseases, a bite from a tick can also lead to an area of inflammation that can be highly noticeable and sometimes painful. Ticks usually take anywhere from 12-24 hours to begin feeding once implanted, which is why quick removal is key to preventing any type of infection.

Some of the diseases transmitted by ticks include the following:

  • Lyme disease
  • Colorado tick fever
  • Tick-borne meningoencephalitis
  • Crimean–Congo hemorrhagic fever
  • Tick-borne relapsing fever
  • Q fever
  • Tick-borne spotted fevers
  • Babesiosis
  • Ehrlichiosis
  • Tularemia

Lyme Disease

The most commonly known disease transmitted by ticks is that of Lyme disease. Lyme disease can be very serious if not taken care of as soon as possible. It can affect both humans and animals.

Lyme disease is carried by blacklegged tick in the Northeastern and Upper Midwestern portions of the United States. It is carried by the western blacklegged tick along the Pacific Coast.


Tularemia is transmitted from the dog tick, the lone star tick and the wood tick to humans. It can be found throughout the country.

Tick-Borne Relapsing Fever

This disease is transmitted through soft ticks and has been reported in just 15 states: Arizona, California, Colorado, Idaho, Kansas, Montana, Nevada, New Mexico, Ohio, Oklahoma, Oregon, Texas, Utah, Washington, and Wyoming. Tick-borne relapsing fever is typically found in people who have stayed in rustic cabins and vacation homes.

Colorado Tick Fever

Colorado tick fever is only found in Rocky Mountain states at elevations of 4,000 to 10,500 feet. It is transmitted by the Rocky Mountain wood tick.
