Not Just Lyme Disease: Tick-Borne Illness in Virginia

dog ticks don't cause Lyme disease but can give you other tick-borne illness
A bite from this dog tick doesn’t cause Lyme disease but can lead to ehrlichiosis and Rocky Mountain spotted fever.

Along with the summer come longer days, vacation planning, planting gardens, hiking — and tick-borne illness.

According to WSET, we’re in for another big tick season. That’s because relatively mild winters, like the past couple of winters in central Virginia, allow the tick population to grow.

Mail in the Tick

The growth of the tick population plus the rise in tick-borne illness have health officials paying extra attention, too. This year the Virginia Department of Health is asking people who’ve been bitten by a tick to take a quick online survey, and then mail them the tick. They will use this information to better understand where in Virginia certain tick species can be found, as well as which species are biting people.

Tick-Borne Illnesses

You probably know someone who’s had Lyme disease, a bacterial infection that starts with a tick bite. But every year, Virginia residents are diagnosed with two other types of tick-borne illness: Rocky Mountain spotted fever and ehrlichiosis.

“I would definitely say cases of Lyme disease are surging here. And I’ve never used that verb before when it comes to increasing incidence of anything,” says James Nataro, MD, PhD, a pediatric infectious disease expert and physician in chief of UVA Children’s Hospital.

In 2006, Virginia health officials reported 357 cases of Lyme disease to the CDC. In 2016, they reported 976 confirmed cases and another 374 probable cases. And the CDC warns that these numbers don’t reflect every diagnosed case. It estimates that around 300,000 people in the U.S. are diagnosed with Lyme disease every year.

The increase may be due to the bacterium that causes Lyme disease becoming more common in wild mammals and ticks, Nataro explains. And when those wild mammals, like deer, live near humans, the disease spreads easily.

Rocky Mountain spotted fever and ehrlichiosis are not as common as Lyme disease, but UVA sees a few cases each year, Nataro says.

Could That “Flu” Be a Tick-Borne Illness?

Lyme disease, ehrlichiosis and Rocky Mountain spotted fever can have symptoms similar to flu, according to the VDH. Those include:

  • Fever
  • Fatigue
  • Muscle aches
  • Headache

“Patients with Lyme do not appear as acutely ill as those with the other two infections,” Nataro says.

Lyme disease and Rocky Mountain spotted fever have characteristic rashes. Lyme’s is a red, irregular circular rash around the tick bite. The Rocky Mountain spotted fever rash begins on the wrists and hands and spreads to the torso over hours to days, Nataro says.

And anyone infected with Rocky Mountain spotted fever or ehrlichiosis is more likely to have a fever and severe headache, he adds.

If you have these symptoms, see a doctor. Deaths from Lyme disease are very rare, but the other two diseases, particularly Rocky Mountain spotted fever, can be life-threatening if not treated, Nataro says.

All three diseases can be treated with antibiotics. In fact, says Nataro, Lyme disease complications can be treated or avoided by taking antibiotics for less than a month. “Prolonged antibiotics are never necessary,” he says.

Tick Bites Can Cause Meat Allergies, Too

Thomas Platts-Mills, who leads UVA’s Division of Allergy and Clinical Immunology, researches the connection between lone star tick bites and red meat allergies. His team found that in some people, a lone star tick bite triggered the body to produce antibodies that binded to alpha-gal, a sugar in red meat. These people then developed hives or anaphylaxis, but not until several hours after eating the meat.

Avoiding Tick-Borne Illness

Different ticks spread these three diseases. In Virginia:

  • Blacklegged ticks, also called deer ticks, spread Lyme disease and ehrlichiosis.
  • Lone star ticks and dog ticks spread ehrlichiosis and Rocky Mountain spotted fever. Lone star tick bites can also lead to developing the red meat allergy.

Don’t assume you only need to check your body for ticks after a summertime hike. Ticks can live:

  • In wooded areas
  • In tall grass
  • On your pets, if they’re going outside

And they can turn up even during unseasonably warm days in the winter. Nataro diagnosed a case of Lyme disease in December.

If you’re spending time outside, use insect repellent with DEET and wear a hat. Wearing a long-sleeve shirt and long pants if it’s not too hot will also help keep ticks off you. Put your clothes in the dryer for 20 minutes afterwards to kill any ticks on them.

If you do spot a tick on you or your child, grasp its head with tweezers and pull firmly. And if you have trouble getting it off, see a doctor.

    We just moved here to hadensville and have been inundated with ticks…never seen anything quite like it. We live on 7 mostly wooded acres. Is this normal? What can we do. We love it here but it’s this bad now what about the summer

  2. Megan Rowe says:

    I asked Dr. Nataro, and he says spring and fall are the worst times for ticks. It should actually be better in the summer.

  3. mark says:

    we bought a place in Carroll county VA.near hillsville,it was late fall,early winter,had already been snow on the ground and temps below freezing,when it warmed up during the day it was nothing to find 10 ticks on each of us,i had never seen anything like it,wish i had payed more attention to their color etc.they were not as small as what we call seed ticks but the next size up,little smaller than a match head and voracious.now early summer,we have yet to see one.

  4. Karen Kesler says:

    I don’t understand why you are not educating people about Alpha Gal allergy which can occur in certain people after a tick or chigger bite. Dr Thomas Platts-Mills, a UVA professor, has published articles linking tick bites and allergic reactions. I have this allergy. It can be life threatening without an epi-pen after consuming mammalian meat. Please promote awareness of this allergy.

  5. Ann Grigg says:

    Yes, please do sound the warning about alpha gal! I live in central Virginia and have heard of several cases, just in my circle of friends. Many people have not heard of this new tick threat and the consequences of a delayed diagnosis can be life threatening!

  6. Jessica Lowe says:

    Great to see this story! But, given the several peer-reviewed studies, in vivo and in vitro, from top institutions including Johns Hopkins, demonstrating that the Lyme bacteria has a persistent form that is not addressed by current short antibiotic regimes, such a definitive statement about antibiotics seems irresponsible.

  7. Jana Pearce says:

    I am an admin on the largest Facebook group for people to discuss and find out more about alpha-Gal allergy which is (also called mammalian meat allergy https://www.facebook.com/groups/alphagal/
    Over the past two weeks, we have had an unprecedented number of people join the group – we have had over 100 people join! This allergy is very real.
    Never before have we had so many people join because they have been diagnosed with alpha-Gal allergy or are supporting a family member who has contracted this allergy to meat and often also to dairy products after being bitten by ticks.
    Be careful folks – there is no cure for this life-changing allergy, therefore, preventing tick bites is paramount.
