Some Basics...
- Ticks are small, brown insects that are found in wooded or grassy areas. They can attach to people. Ticks then suck and feed on a person’s blood. Ticks become swollen after they feed on blood. These are called “engorged ticks.” Ticks are easier to see and remove when engorged.
- A tick bite is painless and doesn't itch. Because of this, a person may not even notice a tick. A tick sucks a person’s blood until it is full. Then it falls off. This usually takes 3-6 days.
- Ticks can spread many diseases. These include Lyme disease, Rocky Mountain spotted fever (RMSF), and Colorado tick fever.
Type of Ticks
There are two main types of ticks: Wood Ticks and Deer Ticks.
- The Wood Tick: This is also called a dog tick. It is the size of a watermelon seed. It can sometimes spread Rocky Mountain spotted fever and Colorado tick fever. The Lone Star tick is the same size and commonly spreads human monocytic ehrlichiosis. It also sometimes spreads Lyme disease.
- The Deer Tick: This is also called the black-legged tick. It is between the size of a poppy seed and an apple seed. It is the tick that most often spreads Lyme disease. A Southern form of Lyme disease can be spread by the Lone Star tick.
What is Lyme Disease?
- This has become the most common tick-borne illness in the United States. The risk of Lyme disease after a deer tick bite is about 1%.
- Most cases of Lyme disease start with a bull's eye rash at the site of the bite. The rash can appear days to weeks after a tick bite. This is often 7-10 days later. If a rash appears, antibiotics are needed. There may be flu-like symptoms with the rash. These include fever, chills, headaches, muscle aches, and fatigue.
- Getting the tick off right away will help prevent Lyme disease.
