I keep seeing headlines about bird flu, and it’s freaking me out. I have a big trip coming up to climb a bunch of fourteeners in Colorado, but it sounds like bird flu is all over the state right now. I’m wondering how worried I should be and whether I should cancel my vacation. What can I do to protect myself from getting the bird flu? — Anxious Traveler

If you’re just about packed for an adventure in a new state, your newsfeed might be giving you some jitters—especially if you’re consistently seeing headlines about a viral disease jumping from animals to people. You might feel worried about that hiking trip in Colorado, especially given the rampant bird flu outbreak in the state. However, the current H5 bird flu (also called avian influenza or H5N1), which has jumped from birds to cows to people, is much different than COVID-19, according to experts who spoke to şÚÁĎłÔąĎÍř. Right now is a time to build awareness, not pull a Crowdstrike on your travel plans.

At the time of publication, there have been 14 cases of H5 bird flu in people since 2022. It’s running rampant in cows and has been since March of this year. The 179 cases in livestock herds across 13 states, with the majority occurring in Colorado. The state also recently reportedĚýten cases of the H5 bird flu in humans, making it the in humans in U.S. history.

Ten is still a relatively low number of human cases, but experts are concerned for several reasons.

“I’ve been studying fluĚýfor fourteen years,” said , an assistant professor of veterinary and biomedical sciences at Penn State College of Veterinary Sciences, “and we’ve never seen a flu virus expand its host range quite this much in this short period of time.” Also called host range expansion, this defines a virus’s ability to increase the types of species it’s able to infect.

This host range expansion is interesting from a virology standpoint, Sutton said, and it’s also why the flu community is concerned about it.

What Exactly Is Bird Flu?

The bird flu we’re talking about is the H5 bird flu, a strain of Goose Guangdong virus, which gets its name from the animal and location in China where it was first found in 1996.

In 1997, the first human bird flu infections occurred in Hong Kong. “Sporadically,” Sutton said, “they’d be carried by migratory birds to Europe, where they would cause outbreaks. Then, they’d kill all the chickens, and the outbreak would go away.”

However, a few years ago, the bird flu became endemic in wild birds, and migratory birds from Europe brought it to North America. “These viruses used to be in one place,” Sutton said. “Now they’re everywhere.”

In recent weeks, over chickens have been infected in the U.S., the majority of which have been detected in Colorado. Up in Minnesota, 41,500 birds have been infected.

Bird flu can propagate in multiple ways. As the numbers show, it usually spreads rapidly between birds via mucus, saliva, or feces, according to the (CDC). However, people can contract it by breathing in these same particles or making contact with contaminated surfaces. The National Institutes of HealthĚý(NIH) reported that infected cows are not very efficient in transmitting the virus via airborne particles but can infect other mammals with raw milk.

Where Bird Flu Cases Are Rising—and What You Should Be Aware of

Those infected with the bird flu primarily work on poultry and dairy farms with direct exposure to infected animals, said , a Yale Medicine infectious diseases specialist and assistant professor of medicine at Yale School of Medicine. As of right now, there’s still no evidence of human-to-human spread. Humans appear to be “functionally dead-end hosts” of this virus, he says, meaning people cannot transmit the virus to other humans.

Roberts said the risk of getting H5N1 is pretty low right now for most people. But there’s a reason why this virus is getting so much attention. For one, it’s clearly adapting to infect animals other than birds. According to Roberts, “One has to ask the natural question: How long is it until it jumps to humans in a sustained way?”

While the average person has a low risk of contracting H5N1, there is a broader food supply and labor issue highlighted by the spread of bird flu.

So far, Roberts said, the cases have been mild in humans—mostly conjunctivitis (a fancy term that refers to inflammation of the membrane that lines the eyeball and eyelid, a.k.a. “pink eye”). This is rather surprising as these not-so-serious cases “really bucked the trend of the historic fifty-percent death rate.”

SomeĚýprecautionary measures, like eyewear, weren’t necessarily adhered to because of extreme heat. In Colorado, five farm workers who contracted the virus—while culling an infected bird flock—were working in 104-plus degree temperatures, as .

“We need to take this seriously,” Roberts said. Many workers on farms are undocumented, which limits their ability to seek out healthcare even if they do get sick. Having logistics to test people onsite, he said, would help, along with resources to allow them to stay home if they are sick to avoid further spread.

“The concern right now is that the more these viruses get used to living and replicating in a mammal, the more they can adapt to do that,” Sutton said. The more humans are exposed to infected cows, the more likely they are to get infected. Every time that happens, it creates another opportunity for the virus to evolve.

“In essence, each human infection is like buying a lottery ticket for a lottery you don’t want to win,” said Roberts.

How Can I Protect Myself From Bird Flu When I’m Traveling?

If you’re planning on getting outside to soak up the last few weeks of summer, there are a few expert-backed precautions you should take note of.

“There’s very clear scientific data and evidence to show that from an infected cow, there is lots of virus in raw milk,” Sutton said. And in case you were previously inclined to do so: “If you find dead birds, I would avoid touching them,” Sutton said. Instead, contact animal control.

Aside from raw milk, Roberts suggests avoiding raw egg products. “All natural?ĚýI’m all for it, but not when it comes to safety risks.” There are many other bacteria, such as listeria, that love raw milk and can be fatal in humans.

If you live in an area where there are currently ongoing bird flu outbreaks in dairy cows, Roberts also suggests steering clear of dairy farms.

Roberts notes that the CDC and the WHO both designate the risk of human infection as low at this time. Aside from visiting the affected farms or parts of the United States (or the world) where slaughtering chickens and eating raw meat occurs, the risk is pretty low. “I wouldn’t really change my behavior aside from avoiding those places,” he said.

For theĚýgame hunters out there, the CDC recommends avoiding handling visibly sick birds and dressing birds in the field when possible—noting that birds that appear healthy can still carry the virus. The organization also recommends wearing gloves while dressing the bird and thoroughly sanitizing your hands afterward.

It’s worth noting that the current flu shots do not prevent you from getting the bird flu. But pre-pandemic vaccines for H5N1 are being prepared for human use, Sutton said, in case it does become a widespread problem in humans.

If your favorite local farm experiences an infection or outbreak, that doesn’t mean you have to cut them out of your grocery plans forever. As Sutton explained, the government reimburses farmers for culling chicken flocks to quell the infections and restart production. But in the meantime, if you can, avoid buying from farms with ongoing outbreaks, and, for obvious reasons, don’t book a slaughterhouse tour anytime soon.

Unless your travel plans revolve around visiting dairy farms, handling wild birds, or attending a raw milk tasting, you’re probably good to go.

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. şÚÁĎłÔąĎÍř 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, senior research scientist at Yale School of Public Health and Yale School of 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 each year in the U.S.) The reasonsĚýfor 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.

Different Types of Ticks—and the Diseases They Carry

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 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 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.

Why Ticks Are Going Viral

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 . 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 deerĚýas all-you-can-eat mating hotels, and a single deer can host hundreds of ticks, Krause explains.Ěý“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 researchĚýstrongly 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 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.

How Can I Avoid Tick Bites When I Go şÚÁĎłÔąĎÍř?

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 onĚýa 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 fromĚýmid-May through August,Ěýwhen 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 offeredĚýa 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,Ěýand treating your gear with permethrin, an insecticide that should not be applied directly to your skin. The organization even has to help you find effectiveĚýrepellents (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.

What if You Find a Tick?

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 beĚýtreated 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.

How to Remove Ticks

Gilbert has heard about certain tick-removal techniques like applying Vaseline, olive oil, or burning them off your skin, but herĚýadviceĚýis 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 .

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.
