Possibility of Wildlife-to-Human Crossover Heightens Concern About Chronic Wasting Disease

Each fall, millions of hunters across North America make their way into forests and grasslands to kill deer. Over the winter, people chow down on the venison steaks, sausage, and burgers made from the animals.

These hunters, however, are not just on the front lines of an American tradition. Infectious disease researchers say they are also on the front lines of what could be a serious threat to public : chronic wasting disease.

The neurological disease, which is contagious, rapidly spreading, and always fatal, is caused by misfolded proteins called prions. It currently is known to infect only members of the cervid — elk, deer, reindeer, caribou, and moose.

Animal disease scientists are alarmed about the rapid spread of CWD in deer. Recent research shows that the barrier to a spillover into humans is less formidable than previously believed and that the prions causing the disease may be evolving to become more able to infect humans.

A response to the threat is ramping up. In 2023, a coalition of researchers began “working on a major initiative, bringing together 68 different global experts on various aspects of CWD to really look at what are the challenges ahead should we see a spillover into humans and food production,” said Michael Osterholm, an expert in infectious disease at the University of Minnesota and a leading authority on CWD.

“The bottom-line message is we are quite unprepared,” Osterholm said. “If we saw a spillover right now, we would be in fall. There are no contingency plans for what to do or how to follow up.”

The team of experts is planning for a potential outbreak, focusing on public health surveillance, lab capacity, prion disease diagnostics, surveillance of livestock and wildlife, risk communication, and education and outreach.

Despite the concern, tens of thousands of infected animals have been eaten by people in recent years, yet there have been no known human cases of the disease.

Many hunters have wrestled with how seriously to take the threat of CWD. “The predominant opinion I encounter is that no human being has gotten this disease,” said Steve Rinella, a writer and the founder of MeatEater, a media and lifestyle company focused on hunting and cooking wild game.

They think, “I am not going to worry about it because it hasn't jumped the species barrier,” Rinella said. “That would change dramatically if a hunter got CWD.”

Other prion diseases, such as bovine spongiform encephalopathy, also known as mad cow disease, and Creutzfeldt-Jakob disease, have affected humans. Mad cow claimed the lives of more than 200 people, mostly in the United Kingdom and France. Some experts believe Parkinson's and Alzheimer's also may be caused by prions.

First discovered in Colorado in captive deer in 1967, CWD has since spread widely. It has been found in animals in at least 32 states, four Canadian provinces, and four other foreign countries. It was recently found for the first time in Yellowstone National Park.

Prions behave very differently than viruses and bacteria and are virtually impossible to eradicate. Matthew Dunfee, director of the Chronic Wasting Disease Alliance, said experts call it a “disease from outer space.”

Symptoms are gruesome. The brain deteriorates to a spongy consistency. Sometimes nicknamed “zombie deer disease,” the condition makes infected animals stumble, drool, and stare blankly before they die. There is no treatment or vaccine. And it is extremely difficult to eradicate, whether with disinfectants or with high heat — it even survives autoclaving, or medical sterilization.

Cooking doesn't kill prions, said Osterholm. Unfortunately, he said, “cooking concentrates the prions. It makes it even more likely” people will consume them, he said.

Though CWD is not known to have passed to humans or domestic animals, experts are very concerned about both possibilities, which Osterholm's group just received more than $1.5 million in to study. CWD can infect more parts of an animal's body than other prion diseases like mad cow, which could make it more likely to spread to people who eat venison — if it can jump to humans.

Researchers estimate that between 7,000 and 15,000 infected animals are unknowingly consumed by hunter families annually, a number that increases every year as the disease spreads across the continent. While testing of wild game for CWD is available, it's cumbersome and the tests are not widely used in many places.

A major problem with determining whether CWD has affected humans is that it has a long latency. People who consume prions may not contract the resulting disease until many years later — so, if someone fell sick, there might not be an apparent connection to eaten deer.

Prions are extremely persistent in the environment. They can remain in the ground for many years and even be taken up by plants.

Because the most likely route for spillover is through people who eat venison, quick testing of deer and other cervid carcasses is where prevention is focused. Right now, a hunter may a deer to a check station and have a lymph node sample sent to a lab. It can be a or more before results in, so most hunters skip it.

Montana, for example, is famous for its deer hunting. CWD was first detected in the wild there in 2017 and now has spread across much of the state. Despite warnings and free testing, Montana wildlife have not seen much concern among hunters. “We have not seen a decrease in deer hunting because of this,” said Brian Wakeling, game management chief for the Montana Department of Fish, Wildlife & Parks. In 2022 Montana hunters killed nearly 88,000 deer. Just 5,941 samples were taken, and 253 of those tested positive.

Experts believe a rapid test would greatly increase the number of animals tested and help prevent spillover.

Because of the importance of deer to Indigenous people, several tribal nations in Minnesota are working with experts at the University of Minnesota to come up with ways to monitor and manage the disease. “The threat and potential for the spread of CWD on any of our three reservations has the ability to negatively impact Ojibwe culture and traditions of deer hunting providing venison for our membership,” said Doug McArthur, a tribal biologist for the White Earth Nation, in a statement announcing the program. (The other groups referenced are the Leech Lake Band of Ojibwe and Red Lake Band of Chippewa.) “Tribes must be ready with a plan to manage and mitigate the effects of CWD … to ensure that the time-honored and culturally significant practice of harvesting deer is maintained for future generations.”

Peter Larsen is an assistant professor in the College of Veterinary Medicine at the University of Minnesota and co-director of the Minnesota Center for Prion Research and Outreach. The center was formed to study numerous aspects of prions as part of the push to get ahead of possible spillover. “Our mission is to learn everything we can about not just CWD but other prionlike diseases, including Parkinson's and Alzheimer's disease,” he said. “We are studying the biology and ecology” of the misfolded protein, he said. “How do prions move within the environment? How can we help mitigate risk and improve animal health and welfare?”

Part of that mission is new technology to make testing faster and easier. Researchers have developed a way for hunters to do their own testing, though it can take weeks for results. There's hope for, within the next two years, a test that will reduce the wait time to three to four hours.

“With all the doom and gloom around CWD, we have real solutions that can help us fight this disease in new ways,” said Larsen. “There's some optimism.”

Julie Rovner is chief Washington correspondent and host of KFF Health News' weekly health policy news podcast, “What the Health?” A noted expert on health policy issues, Julie is the author of the critically praised reference book “Health Care Politics and Policy A to Z,” now in its third edition.

Public health are watching with concern since a strain of bird flu spread to dairy cows in at least nine states, and to at least one dairy worker. But in the wake of covid-19, many farmers are loath to let in health authorities for testing.

Meanwhile, another large health company — the Catholic hospital chain Ascension — has been targeted by a cyberattack, leading to serious problems at some facilities.

Among the takeaways from this week's episode:

  • Stumbles in the early response to bird flu bear an uncomfortable resemblance to the early days of covid, the troubles protecting workers who could be exposed to the disease. Notably, the Department of Agriculture benefited from millions in covid relief funds designed to strengthen disease surveillance.
  • Congress is working to extend coverage of telehealth care; the question is, how to pay for it? Lawmakers appear to have settled on a two-year agreement, though more on the extension — including how much it will cost — remains unknown.
  • Speaking of telehealth, a new shows about 20% of medication abortions are supervised via telehealth care. -level restrictions are forcing those in need of abortion care to turn to options farther from home.
  • And new on Medicaid illuminates the number of people falling through the cracks of the health system for low-income and disabled Americans — including how insurance companies benefit from individuals' confusion over whether they have Medicaid coverage at all.

Also this week, Rovner interviews Atul Grover of the Association of American Medical Colleges about its recent analysis showing that graduating medical students are avoiding training in states with abortion bans and major restrictions.

California’s $12 Billion Medicaid Makeover Banks on Nonprofits’ Buy-In

TURLOCK, Calif. — For much of his young life, Jorge Sanchez regularly gasped for air, at times coughing so violently that he'd almost throw up. His mother whisked him to the emergency room late at night and slept with him to make sure he didn't stop breathing.

“He's had these problems since he was born, and I couldn't figure out what was triggering his asthma,” Fabiola Sandoval said of her son, Jorge, now 4. “It's so hard when your child is hurting. I was willing to try anything.”

In January, community health workers visited Sandoval's home in Turlock, a in California's Central Valley where dust from fruit and nut orchards billows through the air. They scoured Sandoval's home for hazards and explained that harsh cleaning products, air fresheners, and airborne dust and pesticides can trigger an asthma attack.

The team also provided Sandoval with air purifiers, a special vacuum cleaner that can suck dust out of the air, hypoallergenic mattress covers, and a humidity sensor — goods that retail for hundreds of dollars. Within a few months, Jorge was breathing easier and was able to and play outside.

The in-home consultation and supplies were paid for by Medi-Cal, California's Medicaid health insurance program for low-income residents. Gov. Gavin Newsom is spearheading an ambitious $12 billion experiment to transform Medi-Cal into both a health insurer and a social services provider, one that relies not only on doctors and nurses, but also community health workers and nonprofit groups that offer dozens of services, including delivering healthy meals and helping homeless people pay for housing.

These groups are redefining health care in California as they compete with businesses for a share of the money, and become a new arm of the sprawling Medi-Cal bureaucracy that serves nearly 15 million low-income residents on an annual budget of $158 billion.

But worker shortages, negotiations with health insurance companies, and learning to navigate complex billing and technology have hamstrung the community groups' ability to deliver the new services: Now into the third year of the ambitious five-year experiment, only a small fraction of eligible patients have received benefits.

“This is still so new, and everyone is just overwhelmed at this point, so it's slow-going,” said Kevin Hamilton, a senior director at the Central California Asthma Collaborative.

The collaborative has served about 3,650 patients, including Sandoval, in eight counties since early 2022, he said. It has years of experience with Medi-Cal patients in the Central Valley and has received about $1.5 million of the new initiative's money.

By contrast, CalOptima Health, Orange County's primary Medi-Cal insurer, is new to offering asthma benefits and has signed up 58 patients so far.

“Asthma services are so difficult to get going” because the nonprofit for these services is virtually nonexistent, said Kelly Bruno-Nelson, CalOptima's executive director for Medi-Cal. “We need more community-based on board because they're the ones who can serve a population that nobody wants to deal with.”

Newsom, a Democrat in his second term, says his signature health care initiative, known as CalAIM, seeks to reduce the cost of caring for the state's sickest and most vulnerable patients, including homeless Californians, foster , former inmates, and people battling addiction disorders.

In addition to in-home asthma remediation, CalAIM offers 13 broad categories of social services, plus a benefit connecting eligible patients with one-on-one care managers to help them obtain anything they need to get healthier, from grocery shopping to finding a job.

The 25 managed-care insurance companies participating in Medi-Cal can choose which services they offer, and contract with community groups to them. Insurers have hammered out about 4,300 large and small contracts with nonprofits and businesses.

So far, about 103,000 Medi-Cal patients have received CalAIM services and roughly 160,000 have been assigned personal care managers, according to state data, a sliver of the hundreds of thousands of patients who likely qualify.

“We're all new to health care, and a lot of this is such a foreign concept,” said Helena Lopez, executive director of A Greater Hope, a nonprofit organization providing social services in Riverside and San Bernardino counties, such as handing out baseball cleats to children to help them be active.

Tiffany Sickler runs Koinonia Family Services, which offers California foster children mental health and other types of care, and even helped a patient pay off parking tickets. But the program is struggling on a shoestring budget.

“If you want to do this, you have to learn all these new systems. It's been a huge learning curve, and very time-consuming and frustrating, especially without adequate funding,” she said.

Brandon Richards, a Newsom spokesperson, defended CalAIM, saying that it was “on the cutting edge of health care” and that the state was working to increase “awareness of these new services and support.”

For nonprofits and businesses, CalAIM is a money-making opportunity — one that top state health hope to make permanent. Health insurers, which receive hefty payments from the state to serve more people and offer new services, share a portion with service providers.

In some places, community groups are competing with national corporations for the new funding, such as Mom's Meals, an Iowa-based company that delivers prepared meals across the United States.

Mom's Meals has an advantage over neighborhood nonprofit groups because it has long served seniors on Medicare and was able to immediately start offering the CalAIM benefit of home-delivered meals for patients with chronic diseases. But even Mom's Meals isn't reaching everyone who qualifies, because doctors and patients don't always know it's an option, said Catherine Macpherson, the company's chief nutrition officer.

“Utilization is not as high as it should be yet,” she said. “But we were well positioned, because we already had departments to do billing and contracting with health care.”

Middleman companies also have their eye on the billions of CalAIM dollars and are popping up to assist small organizations to go up against established ones like Mom's Meals. For instance, the New York-based Nonprofit Finance Fund is advising homeless service providers how to get more contracts and expand benefits.

Full Circle Health Network, with 70 member organizations, is helping smaller nonprofit groups develop and deliver services primarily for families and foster children. Full Circle has signed a deal with Kaiser Permanente, allowing the health care giant to access its network of community groups.

“We're allowing organizations to launch these benefits much faster than they've been able to do and to reach more vulnerable people,” said Camille Schraeder, chief executive of Full Circle. “Many of these are grassroots organizations that have the trust and expertise on the ground, but they're new to health care.”

One of the biggest challenges community groups face is hiring workers, who are key to finding eligible patients and persuading them to participate.

Kathryn Phillips, a workforce expert at the California Health Care Foundation, said there isn't enough seed money for community groups to hire workers and pay for new technology platforms. “They bring the trust that is needed, the cultural competency, the diversity of languages,” she said. “But there needs to be more funding and reimbursement to build this workforce.”

Health insurers say they are trying to increase the workforce. For instance, L.A. Care Health Plan, the largest Medi-Cal insurer in California, has given $66 million to community organizations for hiring and other CalAIM needs, said Sameer Amin, the group's chief medical officer.

“They don't have the staffing to do all this stuff, so we're helping with that all while teaching them how to build up their health care infrastructure,” he said. “Everyone wants a win, but this isn't going to be successful overnight.”

In the Central Valley, Jorge Sanchez is one of the lucky early beneficiaries of CalAIM.

His mother credits the trust she established with community health workers, who spent many hours over multiple visits to teach her how to control her son's asthma.

“I used to love cleaning with bleach” but learned it can trigger breathing problems, Sandoval said.

Since she implemented the health workers' recommendations, Sandoval has been able to let Jorge sleep alone at night for the first time in four years.

this program and all the things available is amazing,” said Sandoval, as she pointed to the dirty dust cup in her new vacuum cleaner. “Now my son doesn't have as many asthma attacks and he can run around and be a normal kid.”
