Scientists are studying why tick-borne infections, including Lyme disease, are on the rise and why ticks are expanding into new geographic areas.

Lyme disease, the most common tick-borne infection, is caused by the bacteria Borrelia burgdorferi and Borrelia mayonii. It's transmitted by the bite of an infected blacklegged tick, previously known as a deer tick.

The Northeast and Upper Midwest are hot spots for Lyme disease, though there are other parts of the U.S. and the world where people have been infected.

Dr. Bobbi Pritt, director of the Clinical Parasitology Laboratory at Mayo Clinic, says it's important to know what to look for and what to do if you are exposed to Lyme disease.

You spend a lot of time outdoors, remove an engorged deer tick from your skin and a few days later notice a rash.

"Patients may present with a rash at the site of the tick bite, and it's classically a bull's-eye rash, although not always," says Dr. Pritt.

It might be time for medical intervention.

Lyme disease is treated with courses of antibiotics. The earlier you treat it, and the earlier you catch the infection and treat it, the better.

Dr. Pritt says that left untreated, symptoms may progress to "disseminated rashes, joint pain, arthritis and even neurologic involvement. And they can even have one-sided facial paralysis called Bell's palsy."

Prevention is the best medicine.

"Wearing permethrin sprayed on clothing also will repel and even kill ticks. And then just covering up with clothing so that the ticks can't get to your skin," says Dr. Pritt. "If you tuck your pants into your socks, you're taking away an avenue for ticks to get to your legs to bite you."

DEAR MAYO CLINIC: A close friend was diagnosed recently with Lyme disease due to a tick bite. However, I recently read about some new type of tick-borne illness. My family loves to hike and be outdoors, but I'm nervous now about continuing our activities. How can I reduce our risk of illness from insect bites and protect my family?

ANSWER: Enjoying the outdoors is a wonderful way to spend quality family time together, but there are certainly some risks, especially from ticks. The tiny bugs, which are closely related to spiders, are nearly everywhere in the U.S. and can transmit several different germs to humans. Two new tick-borne pathogens were detected at Mayo Clinic in the past decade.

The most prevalent and commonly known tick-borne disease in North America is Lyme disease. It's caused by the bacteria Borrelia burgdorferi and Borrelia mayonii and is transmitted by a black-legged tick, also known as a deer tick.

Recently, there has been concern about the Lone Star tick, which carries the Heartland virus, and can cause illness or even death. These ticks have been around a long time, but the numbers are increasing from the southeastern U.S. to other parts of the country. It is important to be educated about ticks and take measures to protect yourself and your family from tick-borne diseases.

To reduce the risk of tick bites, remember these ABCs:

  • Avoid ticks
    Be aware of the places that are more likely to have ticks and try to avoid them. A forest with a lot of areas of undergrowth, leaf litter and tall grasses is a prime place to encounter ticks. If you are going for a hike, look for a clear path and stay in the middle to decrease the chance of encountering ticks.
  • Bug spray
    Whenever you go outdoors, whether it's spring, summer or early fall, apply bug spray. The Centers for Disease Control and Prevention (CDC) recommends applying a bug spray to your skin that contains either DEET 30% or Picaridin. You also could use a bug spray on your skin that has oil of lemon eucalyptus in it. There is also a tick repellent called permethrin that can be sprayed on clothing for an extra layer of protection. Permethrin actually kills ticks, and it will last through several washes. The Environmental Protection Agency has rated all the different types of tick and mosquito repellents, and has shown these ingredients to be very effective in repelling and even killing certain types of insects and ticks.
  • Clothing
    If you're going to be outside and in areas where ticks may be lurking, dress in a way that limits skin exposure and will make it harder for ticks to bite. Something as simple as tucking your pants into your socks can help in this regard. When it is hot outside, it may not be comfortable to wear long pants and long-sleeved shirts, so that's where the combination of clothing and bug spray come together.

In addition to preventive measures, it's very important to check yourself for ticks after coming in from outdoors. That also holds true for other members of your family, your friends and your pets. You should check yourself as soon as you come inside and periodically during the day if you're going to be outdoors for some time. The longer a tick stays attached to your skin while it's feeding, the greater likelihood there is for transmitting some type of harmful pathogen.

To remove a tick, use forceps or fine-tipped tweezers to pinch the tick at the point where its mouthparts are inserted into the skin. Pull the tick out slowly in one continuous motion. You want to avoid twisting or crushing the tick during this process, since that may increase the risk of getting an infection from the tick. Also avoid home remedies for removing ticks, such as putting nail polish or petroleum jelly on the tick or lighting it on fire.

If you have been exposed to ticks, particularly if you have a known tick bite, closely monitor for symptoms of a tick-borne disease, such as rash, flu-like symptoms, fever, fatigue, muscle aches and joint pains. In rare cases, some patients can develop a significant allergy to meat, such as pork, beef or venison, after a tick bite.

A patient that discovers a tick that has been attached for 36 hours or more, or who has any of the symptoms listed above, should see a primary health care professional. Thankfully, there are several tests and new testing algorithms that are available at Mayo Clinic to check for both early- and late-stage disease for all the tick-borne diseases in the U.S.

As ticks continue to expand their ranges and move into other parts of the country, it's even more important to take efforts to reduce your risk of tick-borne diseases. Dr. Bobbi Pritt, Clinical Parasitology Laboratory, Mayo Clinic, Rochester, Minnesota

Lyme disease has infected more than 14% of the world's population, according to a new study. "It's significant," says Dr. Bobbi Pritt, director of the Clinical Parasitology Laboratory at Mayo Clinic.

"If you look at the numbers and how it breaks down in regions across the United States, in some areas, that exceeds 50% seropositivity. That means people are walking around with antibodies in their blood that are detectable. That shows they've been exposed to Lyme disease at some point in their life," says Dr. Pritt. "Now whether it was in the past and they've been successfully treated, or whether they have it right now, you can't tell by that result, but it's a marker of exposure."

Watch: Dr. Bobbi Pritt talks about Lyme disease.

"It's very helpful for people to know that Lyme disease is not just a problem we have in the United States. And that it, of course, goes up into Canada, but also that in Europe and Asia, they also have Lyme disease," says Dr. Pritt.

"And as we raise awareness, there will hopefully be more studies like this to look at where people are getting exposed to Lyme disease, and how many people have been infected in the past. We need to understand the disease and where it is so that we can work on better ways to detect and treat it," she says.

Lyme disease

Lyme disease is a bacterial infection spread by an infected tick. Patients may present with a rash at the site of the tick bite — classically with a bull's-eye rash. But that's not always the case. 

Lyme disease rash

"Also, some people may have a rash and not know if it's on the back of their head or another hard-to-see and hard-to-reach area. If the infection is not treated right away, the patient may then progress to having other symptoms like disseminated rashes, joint pain, arthritis and even neurologic involvement. And they can even have one-sided facial paralysis called Bell's palsy."

Lab tests help confirm or rule out diagnoses of Lyme disease. Mayo Clinic Laboratories perform more than 300,000 tests for tick-borne diseases each year, says Dr. Pritt.

When to seek medical care

Finding a tick on you and removing it promptly is not a reason to seek medical attention, especially for those who live in an area where ticks are a daily occurrence, says Dr. Pritt.

"If a patient lives in an area where there's a lot of Lyme disease, finding a tick that's been attached to them for more than 24 hours, ideally more than 36 hours, that in and of itself is enough to prompt them to go to their physician to see if they should get some antibiotics to prevent Lyme disease," she says.

Dr. Pritt says "If someone were to present with any type of illness during the spring, summer or fall months when they been exposed to ticks, where they may have a

rash, a headache, a fever, those could all be signs of tick-borne diseases, Lyme disease and other diseases. And that should prompt them to go to their physician."

Prevention

The best way to avoid Lyme disease is to avoid getting a tick bite. Dr. Pritt says it's important for people to protect themselves from tick bites. Avoiding tick bites will protect them not just from Lyme disease, but also many other tick-borne infections. 

Note these tick prevention tips:

  • When possible, avoid areas where ticks are frequently found.
  • Use a repellent with 30% or more of DEET.
  • Wear clothing that covers your arms and legs.
  • Tuck pants into socks while hiking.

"I also like oil of lemon eucalyptus, which has been shown by the Environmental Protection Agency to be almost as effective as DEET and smells a little better. Also, wearing permethrin sprayed on clothing is helpful. That also will repel and even kill ticks. And then just covering up with clothing so that the ticks can't get to your skin. If you tuck your pants into your socks, you're taking away an avenue for ticks to get to your legs to bite you."

More cases of Lyme disease and other tick-borne illnesses continue to be reported as the geographic range of ticks expands in North America. A changing climate is one of the influencing factors, says the Centers for Disease Control and Prevention.

"The CDC has clearly said that the number of tick-borne infections in the U.S. that get reported to them every year is increasing, and the tick ranges are expanding throughout the U.S.," says Dr. Bobbi Pritt, director of the Clinical Parasitology Laboratory in Mayo Clinic's Department of Laboratory Medicine and Pathology. "Now we may ask then what impact does climate and climate change have on all of this? Well, the answer is, it's complicated."

Watch: Dr. Bobbi Pritt discusses tickborne illnesses.

Many factors affect tick-borne diseases.

"And you have to think not just of the tick, but also anything it feeds on, which may be a mouse or it may be a deer. And then you also have to think of the behavior of humans," says Dr. Pritt.

Temperatures, humidity and precipitation play a part, as does the length of a season.

"If we have a mild winter and the snow melts early, then the ticks are out earlier, and we have an earlier start to our season," says Dr. Pritt. "But it's not a straightforward relationship with temperature. If the weather gets too hot and dry, well, the ticks don't like that. They are very susceptible to being dried out. Then they'll retreat into the forest undergrowth, and you'll see a decrease in the risk of tick-borne diseases. It's actually not temperature; it's the length of the season in which the ticks are out and biting."

And that's when human behavior plays a role. The longer the warmer season, the more people who are outside and susceptible to tick exposure and bites.

"Climate change has all of those different factors ― not just simply temperature. There are all sorts of different behaviors of the animals, and of the ticks and migratory birds that carry the ticks when they fly ― and then again what humans are doing," Dr. Pritt says.

Of the hundreds of species of ticks worldwide, less than 60 are known to bite and spread disease to humans. Some of the common ticks in the U.S. include the black-legged tick, brown dog tick, Rocky Mountain wood tick and the Lone Star tick.

Lyme disease is perhaps one of the most well-known tick-borne illnesses. It is caused by bacteria transmitted through the bite of an infected black-legged tick. In the U.S., two types of tick-transmitted bacteria cause the illness: Borrelia burgdorferi and Borrelia mayonii. Lyme disease can be a serious, life-threatening disease, affecting many people.

"There are more than 30,000 cases of Lyme disease reported in the U.S. every year. That number greatly underestimates the true number of cases," says Dr. Pritt. "It's now estimated to be more than 475,000 people infected each year with Lyme disease."

Other tick-borne illnesses in the U.S. include:

  • Babesiosis.
  • Ehrlichiosis.
  • Rocky Mountain spotted fever.
  • Anaplasmosis.
  • Southern tick-associated rash illness.
  • Tick-borne relapsing fever.
  • Tularemia.
  • Colorado tick fever.
  • Powassan encephalitis.
  • Q fever.


Prevention remains the best way to avoid tick-borne illnesses.

Dr. Pritt recommends following the ABCs of tick bite prevention:

  • Avoid.
    "You want to avoid the areas where ticks are found. That could be something as simple as just sticking to the middle of the trail. If you're out on a hike, stay away from the tall grasses where the ticks are likely to be found. Don't walk through the leaf litter and kick up all the leaves. Some ticks may be underneath those leaves. Try to avoid areas where you're going to put yourself at risk," says Dr. Pritt.

  • (Use) bug spray.
    "You want to spray bug spray on any exposed skin. I would recommend something that has at least 30% DEET. We also have alternatives. You can use something with picaridin. There's also now oil of lemon eucalyptus that works almost as well as DEET. And then you could spray permethrin on your clothing," says Dr. Pritt. 

  • Cover up.
    "It may be too hot to completely cover up, but if you can, wearing clothing that covers your skin is going to prevent ticks from biting that exposed skin. Something as simple as tucking your pants into your socks as you're hiking through the woods could be an effective way to prevent tick bites."

American dog tick

The American dog tick, also known as a wood tick, is mainly located east of the U.S. Rocky Mountains and in some areas of the Pacific Coast. It's responsible for spreading Rocky Mountain spotted fever and tularemia.

Rocky Mountain wood tick

The Rocky Mountain wood tick is mainly located in the U.S. Rocky Mountain states and southwestern Canada. It's responsible for spreading Colorado tick fever, Rocky Mountain spotted fever and tularemia.

Lone Star tick

The Lone Star tick is mainly located in the southeastern and eastern U.S. It's responsible for spreading ehrlichiosis, Heartland virus disease, southern tick-associated rash illness (STARI), Bourbon virus disease and tularemia. Bites from the Lone Star tick can sometimes lead to alpha-gal syndrome.

Asian longhorned tick

The Asian longhorned tick is usually located in countries including eastern China, Japan, the Russian Far East and Korea. Since 2017, the tick has been found in several eastern states in the United States. The tick can potentially spread germs that cause serious human diseases, such as anaplasmosis, babesiosis, ehrlichiosis and rickettsiosis, but the risk to humans in the United States from this tick is still unknown.

Tick-borne diseases in the U.S. have tripled in recent years, according to the Centers for Disease Control and Prevention. A new study says a warming climate and other environmental changes may play a role in expanding the regions where ticks can be found. This includes the lone star tick, or (Amblyomma americanum).

"There are multiple factors associated with the rise in tick-borne diseases throughout the U.S., and it does appear that climate change is one of these factors," says Dr. Bobbi Pritt, a parasitic and vector-borne diseases expert at Mayo Clinic. "Climate strongly influences the development and survival of ticks in the wild, as well as animals on which they feed, such as deer, rodents and birds. Some of these important climatic factors are temperature, precipitation and humidity."

"For example, take the time that ticks are out feeding," says Dr. Pritt. "Ticks will generally be out looking for blood meal once the snow melts in the spring, and they will remain active to some extent until the snow falls — temperatures around and above 40F. With climate change and global warming, we are seeing earlier springs and shorter, milder winters, with the end result of there being a longer warm season in which humans may be exposed to tick bites."

Lone star tick

"Along with this, the survival and activity of the ticks and animals hosts, such as rodents and deer, is also influenced by climatic factors. Anything that favors increase survival or expansion of these populations can result in an increase in the tick populations. The lone star ticks, in particular, are susceptible to cold winters. Thus global warming may favor their expansion into more northern regions of the country where the winters were previously too cold for the immature ticks to survive.

The lone star tick is common in southern, central and eastern parts of the country and is now reported to be in Midwest and in parts of Canada. The tick can transmits several diseases including ehrlichiosis, alpha gal syndrome (commonly referred to as meat allergy) and a condition called southern tick-associated rash illness.

Dr. Pritt says tick survival and activity increases with temperature up to a point. High temperatures, low humidity and heavy precipitation may decrease tick activity, and prompt ticks to find refuge in woodland. "The length of the season seems to be more important in terms of increased risk of exposure, rather than extremes in temperature."

Other factors that are important to mention, says Dr. Pritt, include modifications to tick and animal habitats, in conjunction with climate change. Examples include habitat fragmentation that creates wooded areas where deer and rodents thrive; loss of biodiversity, such as the loss of the predators that keep deer populations in check; and animal food and habitat resource availability. These modifications to tick and animal habitats will affect the risk of tick exposure for humans. "So, unfortunately, it's a complex story with multiple factors to consider."

Ready or not, ticks are out. Lyme disease is the most common tick-borne illness, but it's not the only concern, says Dr. Bobbi Pritt, a parasitic diseases expert at Mayo Clinic. "There are other tick-borne diseases like anaplasmosis, babesiosis, Powassan virus and Borrelia miyamotoi infection, and those are just diseases transmitted by the black-legged tick, formerly known as the deer tick," says Dr. Pritt. "We have other ticks that will transmit the disease-causing agents of ehrlichiosis. Now there are new viruses, such as Bourbon virus and Heartland virus. And there is also Rocky Mountain spotted fever."

Approximately 300,000 people each year are infected with Lyme disease due to a tick bite, according to the Centers for Disease Control and Prevention. "It's the most common vector-borne disease in the Northern Hemisphere and in North America, in the U.S. specifically," says Dr. Pritt.

"By vector-borne, we mean something that can transmit an infectious organism, be it a bacterium, a virus or a parasite, to a human. Lyme disease is caused by Borrelia burgdorferi. It's also caused by Borrelia mayonii, which we helped to identify here at Mayo Clinic."

extreme close up with high magnification of tick embedded in human skin

Here are some tips to protect yourself from ticks and mosquitoes:

  • When possible, avoid areas where ticks and mosquitoes are more frequently found.
  • Use repellent with 30 % or more of DEET.
  • Wear clothing that covers your arms and legs.
  • Tuck pants into socks while hiking.

If bitten by a tick, you should:

  • Remove the tick promptly and carefully. Use fine-tipped forceps or tweezers to grasp the tick as close to your skin as possible. Gently pull out the tick using a slow and steady upward motion. Avoid twisting or squeezing the tick. Don't handle the tick with bare hands. Experts don't recommend using petroleum jelly, fingernail polish or a hot match to remove a tick.
  • If possible, seal the tick in a container. Put the container in a freezer. Your health care provider may want to see the tick if you develop new symptoms.
  • Wash your hands and the bite site. Use warm water and soap, rubbing alcohol, or an iodine scrub

A Wisconsin woman has died of Rocky Mountain spotted fever in what Wisconsin health officials have confirmed is the first documented death from the infection in the state.

"Rocky Mountain spotted fever is an uncommon but very serious tick-borne illness that can lead to death if untreated," says Dr. Bobbi Pritt, a parasitic diseases expert at Mayo Clinic.

It is very rare in Wisconsin. Only 69 cases have been reported from this state during the past five years. And most, if not all, of these infections were likely acquired outside of Wisconsin. However, we know that locally acquired cases have been reported from Wisconsin’s neighboring state, Minnesota. So it’s not a surprise that a patient exposed to ticks in Wisconsin got this potentially deadly infection.

Rocky Mountain spotted fever is caused by infection with a bacterium called Rickettsia rickettsii. In the upper Midwest, it is transmitted through the bite of a Dermacentor variabilis tick, also known as a "wood’ tick" or "American dog tick." However, other ticks in the U.S. also can transmit this pathogen. Dr. Pritt says it is most commonly reported from patients in the southeastern and south central U.S. Missouri, Arkansas, North Carolina, Tennessee, and Oklahoma have the most cases each year.

Those infected with the tick-borne disease may begin to show symptoms 3 to 12 days after being infected.

Symptoms may include:

  • High fever
  • Chills
  • Severe headache
  • Muscle aches
  • Nausea and vomiting
  • Confusion or other neurological changes

"Rocky Mountain spotted fever is another tick-borne disease that residents of Wisconsin and other states need to worry about. And therefore it’s essential to take steps to avoid all tick bites. People often think that 'black-legged ticks' – also known as 'deer ticks' are the only ones to worry about, but the dog ticks are also important to avoid," says Dr. Pritt.

To prevent tick bites, you should:

  • Avoid areas where ticks and mosquitoes live.
  • Use repellent with 30 percent or more of DEET.
  • Wear clothing to cover arms and legs.
  • Tuck pants into socks while hiking.
  • Perform a thorough tick check after being outdoors.

"With ticks, some of it is knowing where their habitat is — staying out of low-growing vegetation, bushes, shrubs — so something as simple as staying to the middle of a path," says Dr. Pritt. "If you’re going on a hike, stay in the middle. Avoid the grasses — the tall grasses on either side."

Dr. Pritt also recommends using insect repellent. "Wearing permethrin on your clothing and spraying a repellent on your skin, especially if you’re going out into the deep woods and you really think you’re going to be exposed, that’s going to be your maximum prevention method."
