Lyme-infected ticks found in eastern national parks
from the Entomological Society of America, Jan. 3, 2017:
Lyme disease has been spreading across the United States over the past several decades, and a new study has confirmed that ticks carrying the disease are present in eastern national parks.
According to the study published in the Journal of Medical Entomology, researchers from the Centers for Disease Control and Prevention (CDC) and the National Park Service (NPS) collected ticks along hiking trails in nine eastern national parks. They found blacklegged ticks (Ixodes scapularis), also called deer ticks, infected with the bacteria that causes Lyme disease in all nine parks. The study is the first to confirm the presence of these ticks, which researchers already suspected because Lyme disease has been reported in the region.
“We know Lyme disease is increasing both in numbers of infections and in geographic range in the United States,” said Tammi Johnson, one of the researchers from the CDC. “This is the first large-scale survey in multiple national parks, and though suspected, it had not been previously confirmed that ticks in many of these parks were infected. It’s quite likely that ticks infected with Lyme disease spirochetes are present in other parks in Lyme disease endemic areas, too.”
This new discovery shouldn’t come as a surprise, according to the study’s authors.
“These tick-borne diseases occur in this area of the country,” continued Danielle Buttke, a study co-author from the NPS. “Having local information about real-time risk can help motivate visitors to reduce that risk.”
And how can park visitors reduce that risk? Here are some of the best ways, according the CDC and NPS:
- Use repellents that contain 20-30 percent DEET on exposed skin and clothing.
- Use products that contain permethrin on clothing.
- Shower within two hours of leaving a tick-prone area to wash off ticks that may be crawling on you.
- Check yourself for ticks and remove attached ticks.
- Dry clothes in a dryer on high heat for 10 minutes to kill any ticks on your clothing.
- Check pets and gear for ticks.
- Hike in the center of trails.
- Avoid sitting down or leaning on logs or bushes along the trail.
“The results of this study serve as a reminder that, while enjoying the parks, visitors can and should take steps to help protect themselves and their loved ones from tick and other bites,” said Johnson.
Buttke also wants to make sure potential visitors know they shouldn’t be scared to visit the parks, and the positives of parks still outweigh the risk of Lyme disease.
“Tick-borne diseases are preventable and treatable,” she said. “They are a serious public health problem, but the burden of chronic diseases such as heart disease, diabetes, and poor mental health is so much greater, and all have the potential to be improved by being active in the great outdoors.”
Furthermore, the NPS is actively working to help protect visitors through prevention efforts and research.
“We have an active tick-borne disease prevention program, which includes education for both visitors and employees,” said Buttke. “We are also currently involved in research to better understand why tick-borne disease is expanding on such a dramatic scale.”
The nine parks the researchers studied were Acadia National Park, Catoctin Mountain Park, Fire Island National Seashore, Gettysburg National Military Park, Manassas National Battlefield Park, Monocacy National Battlefield, Prince William Forest Park, Rock Creek Park, and Shenandoah National Park.

I am so glad that the CDC still ignores the existence of CHRONIC lyme Disease. That they insist on pretending it doesn’t exist despite so many who have their lives destroyed by it. That, on one hand they insist on how easily preventable and treatable Lyme disease is, while at the same time fostering an environment so strong in denial among doctors and other medical staff, that they will not even acknowledge the very real and debilitating symptoms of chronic lyme disease, let alone do anything to help prevent it or develop treatments for it. I have had over 20 doctors deny me help, including my long term primary doctor (this all happened over decade ago). Several were flat out unprofessional and cruel – being sarcastic, making fun of me, even just giving me dirty looks when i let them know i was disabled due to chronic lyme disease.

@apildawn My poor daughter went through the same thing you have. Going through so many doctors telling her to get on with her life etc. She was only 15 and lost all her teen years and her 20’s till she was diagnosed. By then it had gone through her joints, nervous system, heart and finally her brain. Most doctors in Florida went by the CDC standards if Elisa test positive then do the Western Blot? My daughter will always have Chronic Lyme and her brain is still relearning things all over again. Sad thing is, her father is a physician and went by the CDC standards.

Dear Ms. Roca, retired P.A.here w/WesternBlot/IgG-IgM confirmedxStanfordLabs+Quest Labs. My first visit To a Lyme-literate literate MD was shocking, as a young teenager crawled in on all fours with a mother following her…with the wheelchair in hand. The young lady crawled into the bathroom and closed the door and it was just her mother and I in the waiting room. I introduced myself, told her of my background and that Dr. Ledtke MD had diagnosed me with LYME. She told me her teenage daughter had the same. My thoughts are with you and your family. Best wishes JOHN…. We never discussed LYME in medical school. The Europeans seem to have a good handle on the situation as they have been aware of it for hundreds and hundreds of years. You and your daughter will be in my thoughts this evening.

There are ticks with Lyme in Parks out East?
I couldn’t believe it.
Of course there are.
What’s going on here?
