Ticks are well known for spreading a disease that is commonly referred to as Lyme disease. It is caused by a type of bacterium known as borrelia burgdorferi that is carried by ticks. When the tick attaches itself as a parasite and feeds on the blood of a human or an animal, the bacterium can be transmitted into the host's bloodstream. People who live or spend significant amounts of time in grassy places and wooded areas where ticks commonly live and breed are at the highest risk of being infected with Lyme disease.

Because the disease can cause a number of unpleasant symptoms, experts recommend that people exercise caution when spending time in areas where ticks are prevalent. It is a good idea to wear long pants and long sleeves to minimize the amount of exposed skin, and using tick repellant can be additionally beneficial. Even when such precautions are taken, it is a good idea to check yourself for ticks after spending any amount of time in such areas. Catching Lyme disease in its earliest stages is the most important step in preventing long term complications.

In the early stages, the most common sign of Lyme disease is a bull's-eye shaped rash that originates in the area of the tick bite. This rash, which is present in as many as 80% of people with Lyme disease, typically begins as a small red bump and expands to a rash that can be up to 12 inches in width. The rash may become present anytime within a month following the bite. Rashes are often accompanied by flu-like symptoms such chills, fever, body aches, and headaches.

When Lyme disease reaches a more advanced stage, however, it can cause more severe complications and lead to chronic Lyme disease. Chronic Lyme disease symptoms include joint pain and swelling. As the disease progresses, inflammation can become permanent and lead to what is known as Lyme disease arthritis. Chronic Lyme disease can also cause paralysis of the face, weakness and numbness in the limbs, and impaired muscle movement.

If you think you may have Lyme disease, it is important to see your doctor immediately. Doing so can help to prevent the long term symptoms of chronic Lyme disease.
