As a kid, I remember I got a tick on the back of my neck. My mother called the doctor frantically because she thought I'd get Lyme disease. We found out from this experience, that if you notice you have a tick or that you've been bitten, it doesn't automatically mean you have Lyme disease.

OK, so what is Lyme disease? Lyme disease is caused by a bacterium (called Borrelia burgdorferi in case you were wondering), which is transmitted by a bite from infected black-legged ticks. In the northeastern and north-central U.S., the blacklegged tick (or deer tick) transmits Lyme disease. In the Pacific coastal U.S., the disease is spread by the western blacklegged tick.

How do ticks get Lyme disease? When they feed on an infected animal, the tick takes the bacterium into its body. It sounds gross, but the bacterium lives in the gut of the tick, and the next time it goes to feed, the tick could transmit the bacterium to its new host. Due to their small size ticks can go unnoticed, so it is important to watch for initial symptoms of Lyme disease such as:

If left untreated the infection can spread to the joints, heart, and nervous system, causing painful symptoms and loss of muscle tone on one or both sides of the face (called Facial or "Bell's" Palsy). A lab test will determine if you have Lyme disease, and a few weeks of antibiotics will successfully treat the infection.

If you notice a rash like this, see your doctor immediately. Here are some tips for preventing Lyme disease:

  • Cover your body when going out in the woods - wear long sleeves and tuck socks over the bottom of your pants.
