Norovirus on the PCT . . . How an outbreak spreads along the trail

September 24

By Pien Huang for NPR

I was just corresponding with another PCT-hiking friend about the few times we have felt unsafe on the trail. All of our examples related, not to bears or rattlesnakes or even lightning (I might have included lightning had I thought about it more), to human encounters. A lost soul or two on the trail, hunters combining alcohol and firearms, a camping area near a road. Now here is another thing to worry about . . . norovirus. It is a good reminder not to abandon hygiene in the wilderness. RH

EIS officer Arran Hamlet walks into the Government Meadows site to conduct environmental sampling for norovirus.

Last September, Kevin Quinn was trekking through a remote, mountainous region in central Washington state, when he started feeling sick. "At first, I thought it was just a stomachache," he says, "But when we got to the campsite I started throwing up, and it started coming out the other end as well."

Quinn was on the trail with his daughter, who had left her job so they could hike together. After months of hiking, he found himself wiped out at a campsite in the middle of nowhere.

"I had heard about the norovirus for years, but it was always in the context of 'Oh, there's a cruise ship in the Caribbean,'" he says, "You don't think about this being an issue when you're out on the Pacific Crest Trail."

Norovirus is a highly contagious virus that can cause serious gastrointestinal distress for several days. It's often associated with enclosed, crowded settings like cruise ships, health care facilities and childcare centers.

But it also crops up in the wilderness – like in an outbreak among hikers like Quinn last year which was documented in a recent investigation by the Centers for Disease Control and Prevention.

Call in the disease detectives

After a stream of sick Pacific Crest Trail hikers came through the Washington Alpine Club Lodge near Snoqualmie Pass last summer, a volunteer named Robert Henry closed the dorm-style lodge and emailed health authorities.

"My concern at the time was to make sure that the hikers on the trail didn't get any worse, and to make sure that the volunteers at the Washington Alpine Club didn't contract whatever it was they were bringing in," Henry ways. He also worked to warn other hikers about the threat.

EIS officer Dr. Arran Hamlet observes a water source being tested for environmental contamination of fecal waste and norovirus.

Hamlet focused on a 70-mile stretch of trail south of the Lodge, where ill hikers were coming from. One common rest stop, he learned, was a remote log cabin in the meadows, with a pit latrine and a stream that's used for drinking water.

Hamlet and his team hiked out to the cabin and tested water from the stream. They also swabbed the toilets, the door handles, the tabletops, the poker chips – anything people were touching. While the water samples came back clean, "every single [surface] swab tested positive for fecal contamination," he says.

"This doesn't mean that we can see human feces on things," he adds, "but at some point in time, there was transmission of human fecal contamination onto every surface in the cabin we swabbed, and also everywhere in the latrine."

The results of the investigation were published this month in the CDC's Morbidity and Mortality Weekly Report. Investigators concluded that there was an outbreak of norovirus on the trail last summer that was spreading between hikers and that "exposure to contaminated surfaces within the cabin and ... latrines likely amplified transmission."

EIS officer Dr. Arran Hamlet swabs a backcountry pit latrine for norovirus sampling during an investigation for an outbreak of gastrointestinal illness among Pacific Crest Trail Hikers in 2022.

Shanna Miko, a nurse epidemiologist at CDC, was part of the field team on the Pacific Crest Trail study — and it wasn't her first norovirus-in-the-woods investigation. Last year, she traced an outbreak at the Grand Canyon, among people who were backcountry hiking and whitewater rafting.

"These are very well-planned trips. For many people, they're once-in-a-lifetime," she says. Travelers often read books and blogs in preparation, and get advice from others who have done the trip before them, accumulating trail wisdom – "places where people frequently stop, or places that have shelters where people frequently sleep over," good places to get water, or use the bathroom, she says.

These hubs, which seem so remote, see thousands of people – in varying levels of wellness – pass through in a season. They may not leave visible traces but some may leave germs, like norovirus, that can live on environmental surfaces for a long time, Miko says. (According to the CDC, this hardy virus can stay alive on surfaces for "days or weeks.")

Hand sanitizer doesn't cut and other advice for staying well

With norovirus, hand sanitizer and common water filters don't work. The virus is small, and "extra sticky" on skin, Miko says. And it takes just a few dozen viral particles to make a person very ill.

Miko says there are ways that hikers can cut their risks.

Always wash your hands with soap and water after you have a bowel movement – and wash them again before you eat. "The soap is a great detergent to remove the virus from your hands," she says. While any soap and water will work, she recommends biodegradable soaps in protected national parks and backcountry woods to reduce the impact on the environment.

Make sure to drink and cook with good, clean water. Pay attention to where the water comes from, and treat it properly. "Boiling for at least three minutes is the best way to kill everything you would typically come across," Miko says. And note: Most water filters are good at removing bacteria and common parasites but they don't cut it when it comes to norovirus. You'll need to layer on either chemical treatment or UV light treatment to kill the virus. (Here's the CDC's breakdown of what works for which pathogens.)

If you do fall ill, shelter in place if you can. This is for your own safety, and for the sake of others, "so you aren't seeding norovirus particles along the trail and putting others at risk," Miko says. This is not the time to try to push ahead but to rest and hydrate. "If possible, try to keep your defecation far from the trail and bury it, and don't prepare food anywhere near where you're using the restroom or vomiting," she says.

The worst of the symptoms usually passes in two to three days, though "you can still spread norovirus after you feel better," Miko says. She recommends waiting at least two days after symptoms have resolved before continuing on.

Norovirus was the last straw

Kevin Quinn set out to hike the Pacific Crest Trail with his daughter, Katie, who had left her job so they could hike together. Norovirus derailed their plans.

He was thirsty, he was really tired – and while he filtered the water, he skipped the additional, chemical treatment. Soon, he knew he'd made a mistake. "I was completely debilitated. I didn't have the energy to set my tent up," he recalls, "All I was doing was, like, every 15 minutes, going off into the woods and either throwing up or having diarrhea."

After a night of being very ill, Quinn and his daughter made a long, slow trek out of the woods. "We never made the whole trail," he says, "We just decided to call it quits."

Earlier in the summer, he caught COVID, which derailed his trail plans for a month. Up ahead, there were wildfires and trail closures. For Quinn, getting norovirus was the last straw.

A year later, he still regrets that he didn't take the time to treat the water properly.

To other hikers – he says: heed the signs, wash your hands and make sure your water is clean. In his experience, it's not worth the risk.

And, we would add, that water treatment options like the Steripen (using UV technology), would seem to be more effective.

Water Scarcity in Idaho

As someone who grew up in Idaho I feel like I have a good understanding of how important agriculture is to our economy. My grandparents had a small farm and I would spend the summers with them learning about the animals and helping in the garden. During my time I saw how important having access to water was.

Water is fundamental for the growth of crops and animals and unfortunately it is not a limitless resource. Due to this it is important that we consider how we allocate our water resources. Focusing in on Idaho much of our water infrastructure was created during the early 1900s and pairing that with the drought conditions we are seeing contributes to us seeing less and less available water.

This problem is putting a strain on Idaho's agriculture sector and by extension Idaho's economy. Idaho's farmlands are responsible for roughly $11.7 billion a year, much of this money is cycled back into the community to benefit the people that live there. This just goes to show how important water is within our community.

Something that is currently going on in Idaho is that the Department of Water Resources has issued a water curtailment on 6 different districts where junior water holders have not been following the approved mitigation plans. A curtailment means that these areas have restricted water usage as the priority lies with more senior water rights holders.

You might be asking yourself what is the difference between a senior and a junior water rights holder is, I know I was. The only difference is that the senior permit holders established water rights prior to March 31st, 1954. These permit holders get first access to the ground water in the East Snake Plain Aquifer.

The East Snake River Plain Aquifer covers over 10,800 square miles of southern Idaho. Water from the aquifer is pumped out for irrigation purposes and funnily enough, most of the water that goes into the aquifer comes from irrigation (about 60%!). It's important to note that because irrigation techniques are changing and the availability of excess water is dwindling, the volume of the aquifer is dwindling as well.

My goal for this blog is to highlight the importance of water not only within our community but also around the world and share more information about how we are upgrading the current systems we have in order to protect this limited resource. I also want to share some of the stories of the people who are impacted by the decreasing availability of water. I think it is important to share this information so that people can understand not only what their money is being used for but also so that they can understand what is going on in their communities.

I would love it if anyone wanted to reach out with any stories, questions, or just wanted to engage in the conversation with me!

I'll be back soon with more stories to share!

The joys of having a private water supply. The water went off just after everyone arrived for the barbecue so I missed the barbecue and worked on temporarily getting it back on again.

Continued the following day with bypassing the pumps with a spare, a more permanent temporary solution and then deconstructing the existing system to take the pumps out. I’ll have a look at those tomorrow.

What Is an Industrial Water Treatment System and How Does It Work?

Water is the lifeblood of countless industrial processes. But unlike the kind that comes out of your tap, industrial water often needs a little extra TLC before it's ready for action. That's where industrial water treatment systems come in. At PureBact, we understand the importance of clean, reliable water for your facility's operations.

Here's a breakdown of what industrial water treatment systems are and how they work:

What is an Industrial Water Treatment System?

An industrial water treatment system is a customized set of processes designed to remove impurities and adjust the properties of water to make it suitable for a specific industrial application. This could involve anything from making boiler feed water ultra-pure to treating wastewater before it's released back into the environment.

Why is Industrial Water Treatment Important?

Untreated water can wreak havoc on your industrial processes. Minerals can cause scaling and corrosion in pipes and equipment, while contaminants can affect product quality. Proper water treatment helps to:

Protect equipment: By removing impurities that can cause corrosion and scaling, you can extend the lifespan of your valuable machinery.

Ensure product quality: Consistent water quality is essential for producing consistent, high-quality products.

Minimize environmental impact: Industrial wastewater treatment helps to remove pollutants before they are released back into the environment.

Reduce operating costs: By preventing equipment damage and ensuring efficient operation, proper water treatment can save you money in the long run.

How Does Industrial Water Treatment Work?

The specific treatment processes used will vary depending on the source water and the desired end product. However, some common methods include:

Pre-treatment: This stage removes large particles such as sand, debris, and organic matter through filtration or sedimentation.

Clarification: Coagulation and flocculation techniques help suspended solids clump together and settle out of the water.

Filtration: Various filtration technologies, like sand filters or membrane filters, remove finer particles and contaminants.

Ion exchange: This process removes unwanted ions by exchanging them for harmless ones.

Deionization: A specialized form of ion exchange that removes both positively and negatively charged ions to create high-purity water.

Disinfection: Chemicals like chlorine or ultraviolet light can be used to kill bacteria and other microorganisms.
