More people in the U.S. are being diagnosed with tick-related diseases every year, but we don't have to let that stop us from getting outdoors.

At home in Brooklyn, New York, my wife and I have discovered ticks on our dog, a pit-boxer mix who lacks the wherewithal to notify us of such an intruder. A few weeks ago, I found a tick—luckily, before it bit—on my arm while visiting Oakland, California. Outside editors have been coming across the disgusting creatures in northern New Mexico, northern Virginia, and coastal Massachusetts.

A decade ago, my little sister contracted Lyme disease in high school, so I have always been paranoid about tick bites. And with growing tick populations, ever more tick-related diseases, and a flurry of headlines about both, I’m sure I’m not alone.

There are hundreds of species of ticks, but the one to be most concerned about in the United States is Ixodes scapularis. The hard-body tick, also known as the blacklegged tick or deer tick, is a vector for a handful of diseases, including Lyme. “It causes far and away the most trouble in terms of health,” says Dr. Peter Krause, a senior research scientist with a specialty in epidemiology and infectious diseases at Yale Medicine.

Ticks are experiencing a largely unwanted glow-up in our current times. The largest vector-borne disease today is still Lyme, says Alison Hinckley, epidemiologist with the Centers for Disease Control and Prevention’s (CDC) Division of Vector-Borne Diseases in Fort Collins, Colorado. She cites a 2021 estimate based on insurance records that shows 476,000 Americans are diagnosed and treated for Lyme disease each year, which can cause headaches, muscle aches, joint swelling, severe fatigue, and even neurological symptoms. (As a point of comparison, only about 2,000 cases of Rocky Mountain spotted fever are reported each year in the U.S.) The reasons for the rise in Lyme range from deer populations to climate change. It’s enough to make me consider trading my hiking boots for gym trainers.

But if we stay inside, the bugs win. So we spoke to some experts to learn why ticks are prospering, what we can do about it, and how to continue to exercise outside safely. The good news? You can take precautions no matter your outdoor sport of choice, and finding a tick doesn’t have to be a five-alarm emergency.

According to the CDC, there are ticks in every state, though different species (carrying different diseases) proliferate in different environments. For instance, the lone star tick, named for a white spot on its back, is often found in Texas, and the brown dog tick thrives in Arizona. Lyme hails from Krause’s home state of Connecticut—it was named for the town of Old Lyme, in the state—but he might also encounter wood ticks and brown dog ticks, which can both transmit Rocky Mountain spotted fever. It’s not very common, he says, but the disease can cause fever, nausea, muscle pain, and a host of other scary symptoms. Despite its name, the lone star tick can also be found in Connecticut (it’s prevalent elsewhere on the East Coast, too, and in the southeastern and south-central United States), and can transmit an infection that leads to Alpha-gal Syndrome, which sometimes causes a permanent allergy to red meat. And that’s just one state. Another tick-borne disease, Babeosis, used to be called “Nantucket fever,” because one of the first cases in America was found on the nearby Massachusetts island in 1969. The Gulf Coast, American dog, and winter ticks transmit different pathogens around the country. You can see what ticks live in your state on the CDC website.

Still, the majority of tick-borne illnesses in the United States are Lyme disease. Ticks have a three-stage life cycle, Krause explains. As larvae, ticks feed on small mammals like mice. If these mammals are carrying Lyme-causing Borrelia bacteria, the tick is now infected and can transmit the disease. The “bloodmeal” (yum!) allows the larvae to molt into its next stage, when it is known as a nymph. At this point, if a nymph feeds on a human, the human will become infected.

Climate change is a major factor in the rise in tick diseases. Ticks need temperate, moist climates—they’ll die if it’s too hot, cold, or dry. Global warming, Krause says, is increasing tick habitat, with more areas becoming warm and humid. Given the southern states are experiencing hot, dry weather, they might have a temporary decrease in tick populations, but that hasn’t yet been shown, he says.

As a point of proof, Krause points to our northern neighbor. Canada was not historically home to Lyme-carrying tick populations, but now sees many cases of Lyme each year, due to both climate change and tick migration. Deer ticks, predictably, travel on the backs of deer and other furry creatures, but they can also attach to birds, Krause says, allowing them to establish a new colony hundreds of miles away.

The second factor that might be fueling today’s tickflation is deer distribution. Adult ticks use deer as all-you-can-eat mating hotels, and a single deer can host hundreds of ticks, Krause explains. “Wherever deer are, there are a lot more ticks than there would be without deer,” he says.

There is some agreement from across the pond. Dr. Lucy Gilbert is a Senior Research Fellow at the University of Glasgow with a focus on ecology, environmental change, and infectious disease ecology, along with evolution and diversity. Her research strongly suggests that the boom in deer distribution and abundance is a greater factor in the proliferation of ticks (though not necessarily Lyme disease) than climate change.

Lyme disease cases surged by 69 percent in 2022, according to the CDC. But even as data collections gets more efficient, there are still likely many cases missed. As STAT News reports, “There are a lot more cases of Lyme disease in the country than are ever reported to the CDC.”

The increase in disease incidence, Gilbert says, may be related to deer and climate change. Additional factors could be better awareness from the public and doctors identifying tick-related diseases, paired with an increase in outdoor recreation.

The simple answer is that activities that put you in tick habitat—long grass or forests with dense shrubs—will be higher risk than sports that don’t. Hiking and running in the woods increase the likelihood that you’ll encounter a tick. Even short grass, like you’d find on a baseball field or soccer pitch, can carry ticks, Krause says. Something on a hard court, like basketball, would be very low-risk.

The CDC recommends staying away from thick vegetation, high grass, and leaf litter and to “walk in the center of trails when hiking,” to avoid brushing up against grass or other plants where ticks might be hanging out.

Riding a bike on a trail might be lower-risk than running it, says Krause, because ticks will have greater difficulty reaching you from the grass, and cyclists are more likely to stay in the center of the trail. Walking may also be safer than trail running, as you’re more likely to avoid brushing any grasses in places with sharp turns, Krause says.

Dr. Kevin DuPrey, a sports medicine specialist, wrote a 2015 article about Lyme disease in athletes for Current Sports Medicine Reports, and he also has firsthand experience. When running cross-country at University of Delaware, Duprey contracted Lyme disease. Before he was diagnosed and treated, he’d experienced mid-race fatigue—to the point of wanting to lie down and nap during the middle of a competition.

Today, as a precaution, DuPrey tries to avoid overgrown trails especially from mid-May through August, when the transmission rate is highest for Lyme and other tick-borne diseases. He’ll check himself for ticks after running, or even mid-run if he’s in an overgrown area.

He recommended bug spray with DEET to repel ticks, but also offered a clothing tip: light-colored threads can make it easier to spot ticks on your body.

The CDC also recommends using EPA-registered insect repellents (like OFF! Active Insect Repellent I), wearing loose-fitting clothing, and treating your gear with permethrin, an insecticide that should not be applied directly to your skin. The organization even has chat bots to help you find effective repellents (they recommend something with DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol, or 2-undecanone) and assessing tick bites.

“In general, DEET, if used as prescribed, is safe,” Krause says. You wouldn’t want to apply it to a small child if they’re going to lick their skin, he says, but considers it safe overall when used as directed. If ingested, it can cause serious side-effects including seizures, according to the National Pesticide Information Center. But aside from a chance of skin irritation, it’s safe to apply topically. Permethrin, which is only suitable for application to gear and clothing, has more safety concerns, says Krause.

When you head back inside, Hinckley recommends you check your clothing and gear for ticks. Then, using a mirror, check your entire body, particularly under your arms, in and around ears, inside your belly button, the backs of your knees, your hair, between your legs, and around your waist. Then, take a shower as soon as possible.

Hinckley also encourages good tick hygiene for pets. Preventative products like topicals, chews, and collars can help, and she advises manual pet-downs for ticks after time outside. This isn’t just for your pets sake—ticks can take a pitstop on your four-legged roommate before making their way to you.

It’s understandable that you might freak out if you find a tick, especially if it’s attached. But if you find it early—within 36 to 48 hours—DuPrey say, the chance of Lyme disease transmission is actually very low.

If you’re uncertain how long it’s been since you were bitten, he advises seeking professional medical advice, especially if you were bit during the summer months, find a circular rash, or experience flu-like symptoms. If caught early, both Krause and Duprey says, Lyme and other tick-borne diseases can be treated with antibiotics.

As an expert who’s closely studied ticks and tick-borne diseases, Gilbert praises the media’s coverage in highlighting tick awareness and Lyme disease. But she says there is sometimes “too much scare-mongering and exaggerating the outcomes of Lyme disease.” While noting that some people progress to chronic Lyme disease, which can be debilitating, the vast majority of people who contract Lyme do not develop a long-term illness.

Gilbert has heard about certain tick-removal techniques like applying Vaseline, olive oil, or burning them off your skin, but her advice is simple: “This is not a good idea!” Instead, she recommends gently plucking the tick off of your skin by its mouth, using fine tweezers or tick tools (available at veterinary clinics, pharmacies, and online) which won’t squash the tick. If you do find a tick, take a picture before you dispose of it, so you can show it to a doctor in the event you need to visit one.

For disposal, the CDC recommends putting the bug in alcohol, a sealed bag, tape, or a soon-to-be-flushed toilet. The CDC also has resources that can help you decide what to do after a tick bite.

People with immunocompromising conditions are at greater risk for tick-borne infection, Krause says, and should exercise additional caution. As a historical example, he notes when Babesia (the parasite that causes Babesiosis) took over Nantucket, an editorial in the New England Journal of Medicine advised people who didn’t have a spleen avoid buying land on Nantucket. (The spleen, which helps fight infection, is crucial in warding off Babesiosis.)

The best path forward might be to channel an anti-Robert Frost mentality. If you’re going to choose a path to hike, run, or a bike, choose a well-worn one, and stay in the center of it. And I’m not sure if Frost wrote a poem about this, but check your body, take a shower, and throw all your clothes in the dryer when you get back inside.

Melissa Jefferson-Wooden delivered a sensational performance in Budapest, storming to victory in the women’s 100m at the inaugural World Athletics Ultimate Championship in a breathtaking 10.62 seconds.

The American produced a superb display of acceleration and composure to claim the World Ultimate Championship title while recording the fastest women’s 100m time in the world this year. Her 10.62 mark underlined her exceptional form and placed her firmly at the top of the global sprinting hierarchy.

Jefferson-Wooden controlled the race through the decisive stages and maintained her form all the way to the finish to secure a statement victory against a field packed with championship pedigree. She crossed the line ahead of Olympic champion Julien Alfred, who clocked 10.74 seconds with a -0.2 m/s wind, while Sha’Carri Richardson took third in 10.76.

Women’s 100m Final

1. Melissa Jefferson-Wooden — 10.62

2. Julien Alfred — 10.74 (-0.2 m/s)

3. Sha’Carri Richardson — 10.76

The victory was especially significant given the quality of the opposition. Jefferson-Wooden held her nerve against Alfred and Richardson, two of the most accomplished sprinters of the current generation, to produce the fastest performance in the world this year when it mattered most.

Alfred once again demonstrated her consistency at the highest level by taking silver, while Richardson completed an all-star podium in a race that brought together three of the biggest names in women’s sprinting.

But beyond the time, the title and the celebration, one of the most touching moments came after the race when Jefferson-Wooden embraced her father, Melvin, in an emotional celebration.

Their moment carried a deeply personal meaning. When Melissa was just 17 years old, she donated her stem cells to help her father undergo a bone marrow transplant after he was diagnosed with myelodysplastic syndrome. Years later, the two shared an unforgettable embrace in Budapest after she had become the World Ultimate Champion.

For Jefferson-Wooden, however, the evening was about far more than a medal. It was the culmination of an extraordinary journey, now highlighted by a world-leading 10.62 seconds on one of the biggest stages in athletics.

With the Ultimate Championship title secured and her father by her side, Jefferson-Wooden leaves Budapest with more than being an ultimate champion. She leaves with momentum, confidence and a powerful statement of intent — turning a high-profile showdown into one of the defining sprint performances of her season.

Audrey Werro has added another major title to her extraordinary season, storming to victory in the women’s 800m at the inaugural World Athletics Ultimate Championships in Budapest.

The Swiss star delivered a commanding performance, taking control from the opening gun and refusing to surrender the lead as she powered through an absorbing battle against two of the biggest names in the event.

Werro stopped the clock at 1:55.88 to become the Ultimate Championships 800m champion, producing another statement performance on one of the sport’s newest and most prestigious stages.

Behind her, Great Britain’s Keely Hodgkinson fought her way to second in 1:56.26, while the Netherlands’ Femke Broeders-Bol completed the podium in 1:56.74.

The result once again brought together the same formidable trio that featured on the podium at the European Championships, but Werro again proved to be the athlete who could rise above the challenge when it mattered most.

Her Budapest triumph is the latest chapter in a season that has already included records, a successful Diamond League Trophy defence and European Championship gold. Now, she can add the Ultimate Championships crown to a growing list of accomplishments.

Werro’s consistency has been particularly impressive in an 800m event packed with elite talent. Rather than simply relying on a fast finish, the Swiss athlete showed her authority by taking the initiative from the beginning and maintaining enough strength and composure to hold off Hodgkinson and Broeders-Bol all the way to the line.

The victory also underlined the remarkable depth of the women’s 800m, with three athletes separated by less than a second at the finish. Hodgkinson’s 1:56.26 and Broeders-Bol’s 1:56.74 showed just how fiercely contested the race was, but Werro’s decision to dictate the pace ultimately gave her the decisive advantage.

For Werro, this was more than another medal. It was another opportunity to demonstrate that her rise is no passing moment. On a stage featuring established champions and elite rivals, she once again produced the performance required to claim the biggest prize.

For Hodgkinson, the silver medal adds another major podium finish, while Broeders-Bol once again demonstrated her ability to compete with the very best over two laps.

But the spotlight in Budapest belonged unmistakably to Werro.

With another championship crown secured, the Swiss star has strengthened her claim as the athlete setting the standard in women’s 800m running. This is Audrey Werro’s era — and the rest of the field is chasing.

Busang Collen Kebinatshipi has delivered another sensational performance, storming to victory in the men’s 400m at the inaugural World Athletics Ultimate Championship in Budapest.

The reigning world champion stopped the clock at an astonishing 43.39 seconds, smashing his own Botswana national record and moving to fifth on the world all-time list.

Kebinatshipi produced a commanding finish to pull away from his rivals and secure the Ultimate Championship title. American star Rai Benjamin finished second in 44.15, while Jereem Richards of Trinidad and Tobago completed the podium in 44.23.

 Men’s 400m

1. Busang Collen Kebinatshipi — 43.39 NR

2. Rai Benjamin — 44.15

3. Jereem Richards — 44.23

The performance is even more remarkable considering that Kebinatshipi had already rewritten the Botswana record just one week ago in Brussels, where he ran 43.40. In Budapest, he lowered that mark by another 0.01 seconds to establish a new national record of 43.39.

That improvement has also propelled the 22-year-old into rare territory. His latest time now ranks him fifth fastest in history over 400m, placing him among an extraordinary group of athletes who have broken the 43.40 barrier.

Kebinatshipi's victory also caps an extraordinary season for the Botswana star. After establishing himself as a global champion, he has continued to demonstrate that he belongs among the very best one-lap runners in the world.

And there is a major reward for his historic night in Budapest: Kebinatshipi walks away as the Ultimate Champion and $150,000 richer.

From another national record to a place among the five fastest 400m runners ever, Kebinatshipi has turned an already remarkable season into something truly special.

Botswana has its latest sprinting superstar — and Kebinatshipi is showing that his ceiling may be even higher than anyone imagined. 

Marileidy Paulino once again proved why she is the undisputed queen of the one-lap event, powering to victory in the women’s 400m at the inaugural World Athletics Ultimate Championship in Budapest.

The Dominican Republic superstar produced a sensational 49.07 seconds to claim gold, pulling decisively away in the final straight and holding off a fiercely competitive field to extend her remarkable unbeaten run.

Paulino delivered her trademark combination of controlled speed and devastating finishing strength. She remained firmly in contention through the opening stages before unleashing her decisive move down the home straight, where she quickly opened a gap on her closest challengers.

Norway’s Henriette Jæger mounted a strong challenge but could not match Paulino’s finishing speed, crossing the line second in an impressive 49.28. Jamaica’s Nickisha Pryce completed the podium after clocking 49.56, ensuring that three of the world’s leading 400m talents occupied the medals.

The result once again underlined Paulino’s extraordinary consistency at the highest level. She entered Budapest as the world leader after running 48.48 in Paris in June, a performance that also set a Diamond League record. She subsequently remained unbeaten throughout her Diamond League campaign, closing the circuit with a meeting-record 48.64 in Brussels.

Budapest has also become a special venue in Paulino’s career. Three years ago, at the same National Athletics Centre, she captured her first individual world title, marking the beginning of another dominant chapter in her career. She later added Olympic gold in Paris in 2024, further establishing herself among the defining 400m athletes of her generation.

The inaugural World Athletics Ultimate Championship has brought together the sport’s biggest stars in a new winner-takes-the-spotlight format, with Olympic and world champions, Diamond League winners and leading performers competing for ultimate honours.

For Paulino, the occasion once again ended with Ultimate Crown on her arms.

With 49.07 seconds, she did more than win another major 400m title. She delivered another statement of authority, powering through the final straight with the confidence and speed that have made her one of the most dominant figures in modern women’s athletics.

Marileidy Paulino remains unbeaten, remains relentless and, once again, remains the queen of the one lap.

Jakob Ingebrigtsen has made a major decision regarding the remainder of his World Athletics Ultimate Championship campaign, confirming that he will withdraw from the men’s 1500m in Budapest despite producing a sensational performance to win the 5,000m title.

The Norwegian superstar stormed to victory in the inaugural Ultimate Championship 5,000m on Friday night, clocking a season-best 12:59.24 and delivering a devastating finishing kick to defeat Olympic 5,000m champion Cole Hocker and American Parker Wolfe.

Ingebrigtsen’s final 100 metres was arguably the defining moment of the race. The Olympic champion produced a remarkable 12.60-second closing 100m, powering away from the field to secure the $150,000 winner’s prize and underline just how far his fitness has progressed since returning from Achilles surgery.

The victory was particularly significant after what has been an extremely difficult period for the 25-year-old. Earlier in the season, Ingebrigtsen faced serious uncertainty over whether he would even be able to compete at the highest level again. His return has gradually gathered momentum, and his performance in Budapest offered perhaps the clearest indication yet that the Norwegian is rediscovering his formidable racing ability.

But rather than risk pushing his recovering body further, Ingebrigtsen has now opted to step away from the 1500m.

The decision means the highly anticipated showdown with British rival Josh Kerr will not take place in Budapest after all. The two stars had been expected to renew one of the biggest rivalries in modern middle-distance running in the 1500m final.

Instead, Ingebrigtsen is looking beyond the immediate opportunity and towards the bigger picture.

“I’m thinking about 2027… Fitness cannot be faked,” the Norwegian said, signalling that protecting his long-term condition has become more important than chasing another major victory only days after his return to peak-level competition.

The decision comes just one week after an emotionally charged Diamond League Final in Brussels, where Ingebrigtsen finished fourth in the 1500m behind Australia’s Cameron Myers, Kenya’s Phanuel Kipkosgei Koech and American Ethan Strand.

After that race, Ingebrigtsen delivered a fiery assessment of his rivals and questioned the tactics surrounding the pacemaking, particularly involving Hocker. He later acknowledged that there had been “a little too much adrenaline and emotion” when microphones were placed in front of him immediately after the race.

Yet his latest decision shows that beneath the emotion and competitive intensity lies a longer-term strategy.

Ingebrigtsen has already demonstrated that he can compete at an elite level again. His 12:59.24 in Budapest was not simply a victory — it was a statement that the Norwegian remains capable of producing a world-class finish even after months of injury rehabilitation.

Now, however, he is choosing not to gamble with that progress.

For a runner who has spent much of the year fighting his way back from injury, another 1500m race could have offered enormous rewards but also carried unnecessary risk. By withdrawing, Ingebrigtsen is effectively prioritising longevity over one more opportunity for immediate glory.

His message is clear: the comeback is underway, but it will not be rushed.

The 5,000m victory has given Ingebrigtsen confidence, momentum and perhaps, most importantly, proof that his body can once again handle elite competition.

Now comes the harder part — knowing when to stop.

With 2027 already firmly in his sights, the Norwegian has chosen recovery over risk. And after everything he has endured, that could ultimately prove to be one of the most important decisions of his comeback.

Jakob Ingebrigtsen is not walking away from the sport. He is protecting his future in it.
