Life Cycle of The Tick

Difference between sign and symptom

• A symptom is any subjective evidence of disease, while a sign is any objective evidence of disease. Therefore, a symptom is a phenomenon that is experienced by the individual affected by the disease, while a sign is a phenomenon that can be detected by someone other than the individual affected by the disease.

• For examples, anxiety pain, and fatigue are all symptoms. In contrast, a bloody nose is a sign of injured blood vessels in the nose that can be detected by a doctor, a nurse, or another observer.

How To Prevent Lyme Disease

• Wear light/protective clothing• Use tick repellents-Permethrin-on clothes only not skin• Use Deet Ex: Deep Woods Off over the age of 12• Check yourself from the woods• Bathe as soon as possible from the woods• Wash clothing in hot water/Hot Dryer heat• Pay special attention to your: Back, Underarms, Groin Area, Head Area• Look for something that looks like a black freckle size.• Check your pet from a woods before they enter the

house• Remove ticks carefully: gentle firm tugging motion

• Use fine-tipped tweezers to grasp the tick as close to the skin's surface as possible.

• Pull upward with steady, even pressure. Don't twist or jerk the tick; this can cause the mouth-parts to break off and remain in the skin. If this happens, remove the mouth-parts with tweezers. If you are unable to remove the mouth easily with clean tweezers, leave it alone go to your doctor for removal.

• After removing the tick, thoroughly clean the bite area and your hands with rubbing alcohol, an iodine scrub, or soap and water.

• Dispose of a live tick by submersing it in alcohol, placing it in a sealed bag/container, wrapping it tightly in tape, take to doctors.

• Never crush a tick with your fingers.

How to Remove a Tick

Review: How to remove a tick!http://www.health.state.ny.us/diseases/communicable/lyme/

What To Do If You Find A Tick

• Monitor tick bite area• Put tick in a container and give to Health

Department or Doctor• Check for Rash for 1-8 weeks after the

bite

Treatment• Penicillin WASH AREA OF THE BITE WITH SOAP/WATER/ANTISEPTIC• CDC recommends a two-step process when testing blood for evidence of

Lyme disease. • Both steps can be done using the same blood sample. • 1) ELISA or IFA test. These tests are designed to be very "sensitive," meaning that almost everyone with Lyme disease, and some people who don't have Lyme disease, will test positive. 

• If the ELISA or IFA is negative: it is highly unlikely that the person has Lyme disease, and no further testing is recommended. 

• If the ELISA or IFA is positive or indeterminate (sometimes called "equivocal")

a second step should be performed to confirm the results.

• Step 2 Western Blot Test
