A park employee at Grand Canyon National Park in Arizona was confirmed to have been exposed to hantavirus, which is rare but often fatal, Coconino County health officials confirmed after the July 4 holiday weekend, according to local news outlet 8newsnow.com.
Officials also confirmed a separate case of rabies exposure at the park.
Newsweek has contacted the National Park Service, Coconino County Health and Human Services and the Arizona Department of Health Services outside of regular working hours via email for comment.

Why It Matters
Hantavirus is primarily spread by deer mice, which are prevalent in the Grand Canyon area. The virus can cause a host of serious, even fatal, illnesses such as hantavirus pulmonary syndrome (HPS) and hemorrhagic fever with renal syndrome (HFRS), according to the Centers for Disease Control and Prevention (CDC).
The CDC said that HPS has a 38 percent fatality rate, while fatality rates for HFRS depend on the virus strain. New Mexico, Arizona, Colorado and California record the highest number of hantavirus infections nationally, although the virus remains rare.
This is not the first time the virus has been traced to a National Park—for example, there were also cases of HPS in visitors to Yosemite National Park in 2012.
What To Know
The virus is typically transmitted from rodent to human, and not human-to-human, usually following exposure to rat or mice urine, droppings or saliva. It can also spread via a bite or scratch, but this is unlikely.
Those who handle and clean up after rodents, such National Park employees, are at higher risk of hantavirus exposure and should take precautions, the CDC advises.
Authorities did not state how the Grand Canyon employee was thought to have been exposed to the virus.
Grand Canyon spokesperson Joelle Baird told the San Francisco news outlet SFGATE that park service is going to "incredible lengths for cleanup" to control the spread of the virus.
The spokesperson informed the outlet that on June 20, the employee began to experience symptoms of HPS and went to Flagstaff Medical Center, where they received treatment.
They have since been released from the hospital and continue to recover but the spokesperson was uncertain of when the employee would return to work, SFGATE reported.
Five cases of hantavirus have been reported in Arizona so far this year, according to local news outlet 8newsnow.com, citing state officials.
Hantavirus hit the headlines earlier this year when an autopsy confirmed that the late actor Gene Hackman's wife, Betsy Arakawa, died from HPS in Santa Fe, New Mexico.
The Grand Canyon National Park has also confirmed a rabies case, which it linked to a bat collected near Kanab Creek Canyon, according to the local news outlet Austin American Stateman.
Health officials reported the bat tested positive for rabies. Two people who had physical contact with the animal received medical evaluation and treatment, according to a statement from the Grand Canyon National Park.
What People Are Saying
The CDC says on its website: "People should avoid contact with rodent urine, droppings, saliva, and nesting materials. If mice or rats are in or around your home, it's important to clean up after them safely. Rodent control is the primary strategy for preventing hantavirus pulmonary syndrome (HPS), a disease caused by infection with certain hantaviruses. Wild rodents near human populations should be controlled and excluded from homes."
The Nevada Office of State Epidemiology says on its website: "In the U.S., deer mice, cotton rats, rice rats, and the white-footed mouse can carry the hantavirus disease. These rodents spread the virus in their urine, droppings, and saliva. People mainly get the virus from breathing in contaminated air such as when cleaning sheds, barns, or garages where infected rodents are found."
What Happens Next
Public health authorities in Arizona are actively monitoring rodent populations and potential hantavirus cases, and the Grand Canyon National Park continues to adhere to a number of protocols regarding hantavirus safety.

Advertisement Nuzzo: People are worried about potential threats and what it means for them. They're looking for trusted information and unfortunately these days I think people are questioning whether the information coming out of our health agencies is correct. ... One of the reasons why we are also tracking this information is because there had been … a lot of change in terms of what data federal health agencies were sharing. We decided to start going directly to state health departments for information. Advertisement Pandemic Center Director Jennifer Nuzzo at a meeting for a new edition of the Tracking Report. Foreground: Research Assistant Alice Im. Kenneth Zirkel How has data changed since COVID-19? Where I do see a difference is that the How is the information you present different than the CDC website? I don't want to give the sense something nefarious is happening. It's not nefarious. Where we have concerning discrepancies is in interpretation of data. There's a period of time where the Secretary of Health and Human Services, Robert F. Kennedy Jr., when getting questions about these Initially, the CDC was only showing a very cursory summary of measles cases. It wasn't showing the breakdown, whether they're hospitalized, or you know, the vaccination status. ... There's now better data on CDC's website, but initially there wasn't. Part of why we're doing this exercise is if something changes we're ready to fill in the gaps. Why is it so surprising that this measles outbreak is happening? United States eliminated measles in 2000. There is no good reason why any country with the technical and financial resources of the United States should have measles, period. It's not to say that other countries haven't struggled with measles outbreaks — they have — including, other high-income countries like us, but measles elimination status is determined by how quickly you respond and contain the outbreaks.

It's based on what's going on in the world. For instance, a few months ago, we were very actively tracking Are you seeing an influx of people who are craving good, scientific information? I think there's always going to be a role for independent expert voices. People want to hear from people in their community. I do think, now, that people are very worried about the integrity of our health agencies, about funding cuts that make it harder to do the important work and research that keeps people healthy. ...

Talk about the global pandemic early warning system intended to 'rapidly detect future outbreaks of infectious diseases with epidemic or pandemic potential?' It's part of the Global Health Exemplars Program. We're studying really interesting approaches to surveillance in four low- and middle-income countries. What we're learning is applicable to all countries, but these are countries who are doing things with surveillance that are starting to allow them not to just understand when an outbreak happens and figure that out early, but perhaps to give them a better sense of what are the conditions that make outbreaks more likely to occur. And then, perhaps, take action to prevent them from occurring in the first place. Advertisement Can you talk a little bit about use of wastewater testing? I think one important innovation that came out of the pandemic … is wastewater surveillance and the increased understanding of it as a potential tool for monitoring infections in a community. We are now using wastewater to monitor other things: influenza, mpox, and it's now just starting to be used for measles. We have been seeing signals of measles infections in states that hadn't yet reported measles cases. This is important because we think that measles cases are being under-detected in the US and wastewater data is giving us even more indication of that. On the site there is a 'testing playbook' for biological emergencies. Can you share more about preparedness and response to these emergencies? If we have to think of what's the single biggest thing that went wrong in the US response to COVID, it was that we didn't quickly establish and scale up the availability of testing. It was a well-acknowledged challenge and yet in 2022 when the mpox outbreaks started happening in the United States, yet again, we were hearing clinicians saying, 'I can't get my patient tested.' There were tests available, but it just wasn't where the patients were. We decided to write the testing playbook to better clarify the different approaches to testing to give busy decision-makers a better set of questions to be asking in response to a biological emergency.

Does Anyone Know What ‘Wellness' Means Anymore?
PHOTOGRAPH: TONJE THILESEN Yes or no: Do you have any idea what 'wellness' is? Depending on where you live and which online rabbit holes you've tripped into, your answer to that question—and your actual definition of wellness—may vary widely. And yet, we're in a moment where wellness is the holy grail du jour, sometimes at the expense of our actual health. There's the softer version of wellness, one characterized by some combination of smoothie consumption and aspirational TikTok videos. Then there are the more hard-line (and health hazardous) variations involving everything from (basically) bleach drinking to parasite cleanses to 'wellness farms' designed to wean you off antidepressants. Regardless of which wellness doctrine you ascribe to, one thing is clear: The business of wellness, now worth, by one estimate, more than $6.3 trillion worldwide, is booming. So too is the politicization. Some of the most prominent figures in the nebulous world of wellness are now, of course, firmly ensconced in key US government roles—and are using their authority to wreak havoc on the lives of Americans. In his first few months leading US Health and Human Services, anti-vax poster boy Robert F. Kennedy Jr. has fired every member of the CDC's advisory committee on immunization practices, replacing them with a mixed bag of credible experts and 'vaccine skeptics'; laid off thousands of civil servants and cut billions in research funding to colleges and public health departments; and used his White House perch to take shots of raw milk on camera. All in the name of Kennedy's anti-science bid to Make America Healthy Again. But don't despair just yet. As you'll read in this issue, robust, invigorating, truly innovative research is still uncovering new tools and therapies, and solving once intractable medical mysteries, in the US and around the world. To that end, we'll take you inside the forefront of AI-fueled drug discovery and the weakened state of cancer research. There's lighter fare, too, like a look at animal wellness hobbies, including iceberg exfoliation. And our trusted Gear team is here to tell you which out-there health products are really worth your hard-earned money. As a recent trip to Paris reminded me, wellness doesn't need to be that complicated. If only we could all eat fresh food, walk a lot, and enjoy a vice or two at an outdoor table. Pair that with a heartfelt vow not to drink anything resembling bleach, and I promise, you're halfway to peak performance already.

'Flesh-eating' bacteria: 2 cases found in Escambia, Santa Rosa counties
Eleven people have contracted Vibrio vulnificus, the so-called "flesh-eating" bacteria, and two of the cases were reported in Escambia and Santa Rosa counties respectively. Vibrio vulnificusa is a naturally occurring bacterial infection found in brackish seawater. People can contract it by exposing open cuts or wounds to the water or by eating raw or undercooked seafood. The FDOH did not specify the sources of the new cases. Four people have died from it so far in 2025, according to the Florida Department of Health. The deaths were in Bay, Broward, Hillsborough and St. Johns counties, the FDOH reported on July 11. If the bacteria infects a person, it can cause the skin and soft tissue around a wound to quickly break down. Treatment may require limb amputation to stop the rapid flesh deterioration, and the infection can be fatal. Last year, there were a record 82 cases and 19 deaths, most of them after October when large areas of the state were flooded by back-to-back hurricanes Helene and Milton. Vibrio vulnificusa requires brackish saltwater to spread. Nationwide, vibriosis from Vibrio vulnificus and other Vibrio bacteria causes an estimated 80,000 illnesses and 100 deaths every year, according to the Centers for Disease Control (CDC). How many people have died from flesh-eating bacteria in Florida? According to the FDOH, four people have died so far in 2025, as of Friday, July 11: Bay County: 1 Broward County: 1 Hillsborough County: 1 St. Johns: 1 Between 2008 and 2025, 178 people in Florida have died from Vibrio vulnificus, according to FDOH records. How many cases of flesh-eating bacteria have been reported in Florida? According to the FDOH, 11 cases have been reported so far in 2025, as of Friday, July 11: Bay County: 1 Broward County: 1 Escambia County: 1 Hillsborough County: 1 Lee County: 1 Manatee County: 1 St. Johns County: 2 Santa Rosa County: 1 Walton County: 1 What is Vibrio vulnificus? The Vibrio vulnificus bacteria can be found in raw or undercooked seafood, saltwater, and brackish water, which is created when fresh water from a river or lake meets the salty water of the sea. Flooding spreads brackish water into places it doesn't usually get to, and people working in floodwaters during and after storms are susceptible. Vibrio vulnificus, while rare, can be life-threatening. Some Vibrio vulnificus infections lead to necrotizing fasciitis, a severe infection in which the flesh around an open wound dies. Without treatment, death can occur in just a few days. People with compromised immune systems, liver disease, or open wounds are at higher risk for Vibrio vulnificus, the FDOH said. What are the symptoms of Vibrio vulnificus or 'flesh-eating bacteria'? (WARNING, AN IMAGE BELOW MAY BE TOO GRAPHIC FOR SOME AUDIENCES) Common symptoms of Vibrio infection may include: Watery diarrhea, often accompanied by stomach cramping, nausea, vomiting, and fever. Bloodstream infection: fever, chills, dangerously low blood pressure, and blistering skin lesions. Wound infection, which may spread to the rest of the body: fever, redness, pain, swelling, warmth, discoloration, and discharge (leaking fluids). If you experience these symptoms after being exposed to floodwaters, seek medical attention immediately. Healthcare professionals can treat the infection with antibiotics, but in extreme cases arms and legs may need to be amputated to remove dead or infected tissue. "Many people with Vibrio vulnificus infection require intensive care or limb amputations," the CDC said on its site, "and about 1 in 5 people with this infection die, sometimes within a day or two of becoming ill." Does 'flesh-eating bacteria' actually eat flesh? While colloquially known as a "flesh-eating bacteria," vibrio vulnificus technically kills flesh rather than "eats" it. Vibrio vulnificus can cause necrotizing fasciitis that kills human tissue, including the skin and outer layer surrounding muscles, nerves, fat, blood vessels and organs. It cannot penetrate intact skin, but must enter through an existing break in the skin. No, but it does kill it. Vibrio vulnificus can cause necrotizing fasciitis that kills human tissue, including the skin and outer layer surrounding muscles, nerves, fat, blood vessels and organs. Calling it 'flesh-eating bacteria' is inaccurate, − though a common reference − because (1) it kills tissue, but does not eat it; and (2) it cannot penetrate intact skin, but must enter through an existing break in the skin. Can you get the flesh-eating bacteria from another person? "There is no evidence of person-to-person transmission of Vibrio vulnificus," the FDOH said. How can I avoid contracting Vibrio vulnificus? According to the FDOH and CDC: Avoid exposure of open wounds or broken skin to warm salt or brackish water, especially flood water, or to raw shellfish harvested from such waters. Stay out of the water, or cover your wound with a waterproof bandage. Immediately wash wounds and cuts thoroughly with soap and water after they have contact with saltwater, brackish water, raw seafood, or its juices. Seek immediate medical care if a wound develops redness, swelling, or oozing, or other signs of infection such as fever, increasing pain, shortness of breath, fast or high heart rate, or confusion or disorientation. Do not eat raw oysters or other raw shellfish. Eat shellfish promptly after cooking and refrigerate leftovers. Cook them thoroughly: Boil shellfish in the shell until the shells open and then for 5 more minutes, or steam them until the shells open and then for 9 more minutes. Boil shucked oysters for at least 3 minutes or fry them in oil for at least 10 minutes at 375 degrees. Do not eat shellfish that does not open during cooking. Avoid cross-contamination of cooked seafood and other foods with raw seafood and juices from raw seafood. Wear protective clothing (e.g., gloves) when handling raw shellfish.
