TICK BITE Definition A tick (small brown bug) is attached to the skin. A tick was recently removed from the skin General Information The bite is painless and doesn't itch; so ticks may go unnoticed for a few days. Ticks eventually fall off on their own after sucking blood for 3 to 6 days. Ticks can transmit many diseases, including Lyme disease, Rocky Mountain spotted fever (RMSF), and Colorado tick fever. The Wood Tick (dog tick) is the size of a watermelon seed and can sometimes transmit Rocky Mountain spotted fever and Colorado tick fever. The Deer Tick (black-legged tick) is between the size of a poppy seed (pin head) and an apple seed, and can sometimes transmit Lyme disease. Engorged ticks: After feeding on blood, both ticks become quite swollen (engorged) and easy to see. Lyme Disease Lyme disease has become the most common tick-borne illness in the United States. The risk of Lyme disease following a recognized deer tick bite is estimated to be 1%. The majority of cases of Lyme disease start with a bull's eye rash ("erythema migrans") at the site of the tick bite. The rash can occur days to weeks (typically 7-10 days) after a tick bite. Treatment with antibiotics is indicated if this rash appears. Flu-like symptoms may accompany the rash, including: fever, chills, headaches, muscle aches, and fatigue. Removing ticks promptly may prevent Lyme disease.

Pull the wood tick straight upward without twisting or crushing it. Maintain a steady pressure until it releases its grip. If tweezers aren't available, use fingers, a loop of thread around the jaws, or a needle between the jaws for traction. Note: covering the tick with petroleum jelly, nail polish or rubbing alcohol doesn't work. Neither does touching the tick with a hot or cold object. Tiny Deer Tick Removal: Needs to be scraped off with a knife blade or credit card edge. Place tick in a sealed container (e.g. glass jar, zip lock plastic bag), in case your doctor wants to see it. Tick's Head Removal: If the wood tick's head breaks off in the skin, it must be removed. Clean the skin. Then use a sterile needle to uncover the head and lift it out or scrape it off. If a very small piece of the head remains, the skin will eventually slough it off. Antibiotic Ointment: Wash the wound and your hands with soap and water after removal to prevent catching any tick disease.  Apply an over the counter antibiotic ointment (e.g. bacitracin) to the bite once. Expected Course: Tick bites normally don't itch or hurt. That's why they often go unnoticed. Prevention of Tick Bites: Prevention is important if you are hiking in tick-infested areas. Wear long pants and a long shirt. Tuck your shirt into your pants. Tuck the cuffs of your pants into your socks or boots. Light-colored clothing is better because the ticks can be seen more easily. Inspect your entire body and your clothing every couple hours. Favorite places are in the hair, so be certain to check your scalp, neck, armpits, and groin. A shower at the end of a hike will help rinse off any tick that is not firmly attached. Call Your Doctor If: You can't remove the tick or the tick's head Fever or rash occur in the next 2 weeks Bite begins to look infected You become worse or develop any of the "Call Your Doctor" symptoms.
