Summarize this article:

The primary carriers of Lyme disease are ticks. Therefore, you need to think about whether you've been in an area where you could pick up ticks. Grassy and wooded areas are typical places ticks hide out, but they can even be in your backyard. Pets can also bring them in from outside. It's also important to know if you're in a high-incidence state. That means your state has had 10 confirmed cases per 100,000 people in the last 3 years. You can find this information at https://www.cdc.gov/lyme/stats/tables.html. It's important to know if you've been bitten by a tick, though it may fall off before you become aware. Still, if you found a tick on you and you are having other symptoms, you should visit with your doctor. Look for ticks all over your whole body any time you've been outdoors, particularly if you've been in a wooded area. They like to get in crevices, so look in your armpits and behind your knees, as well as at your waist, between your legs, and around your scalp. Ticks are little pear-shaped bugs with eight legs. They'll attach themselves to your skin. It is possible to test a tick for Lyme disease. If you find one that's buried in your skin, use fine-tipped tweezers to pull it out. Grasp it as close to the skin as you can and pull it straight out. Place it in a plastic bag with a moist cotton bowl or paper towel. You can also submerge it in alcohol in a small vial. Send it to a testing center to be evaluated.
Consider if you've been in a tick-prone area. Be aware of tick bites. Catch and test the tick.
