The US Centers for Disease Control and Prevention descended into turmoil this week after Health Secretary and zealous anti-vaccine advocate Robert F. Kennedy Jr. ousted the agency’s director, Susan Monarez, who had just weeks ago been confirmed by the Senate and earned Kennedy’s praise for her “unimpeachable scientific credentials.”

It appears those scientific chops are what led to her swift downfall. Since the Department of Health and Human Services announced on X late Wednesday that “Susan Monarez is no longer director” of the CDC, media reports have revealed that her forced removal was over her refusal to bend to Kennedy’s anti-vaccine, anti-science agenda.

The ouster appeared to be a breaking point for the agency overall, which has never fully recovered from the public pummeling it received at the height of the COVID-19 pandemic. In its weakened position, the agency has since endured an onslaught of further criticism, vilification, and misinformation from Kennedy and the Trump administration, which also delivered brutal cuts, significantly slashing CDC’s workforce, shuttering vital health programs, and hamstringing others. Earlier this month, a gunman, warped by vaccine misinformation, opened fire on the CDC’s campus, riddling its buildings with hundreds of bullets, killing a local police officer, and traumatizing agency staff.

Monarez’s expulsion represents the loss of a scientifically qualified leader who could have tried to shield the agency from some ideological attacks. As such, it quickly triggered a cascade of high-profile resignations at the CDC, a mass walkout of its staff, and outrage among lawmakers and health experts. While the fallout of the ouster is ongoing, what is immediately clear is that Kennedy is relentlessly advancing his war against lifesaving vaccines from within the CDC and is forcing his ideological agenda on CDC experts.

Some of those very CDC experts now warn that the CDC can no longer be trusted and the country is less safe.

Here’s what we know so far about the CDC’s downturn:

The ouster

Late Wednesday, The Washington Post reported that, for days prior to her ouster, Monarez had stood firm against Kennedy’s demands that she, and by extension the CDC, blindly support and adopt vaccine restrictions put forward by the agency’s vaccine advisory panel—a panel that Kennedy has utterly compromised. After firing all of its highly qualified, extensively vetted members in June, Kennedy hastily installed hand-selected allies on the Advisory Committee on Immunization Practices (ACIP), who are painfully unqualified but share Kennedy’s hostility toward lifesaving shots. Already, Kennedy’s panel has made recommendations that contradict scientific evidence and public health.

It is widely expected that they will further undo the agency’s evidence-based vaccine recommendations, particularly for COVID-19 and childhood shots. Experts fear that such changes would undermine public confidence in both vaccines and federal guidance, and make vaccines more difficult, if not impossible, for Americans to obtain. Kennedy has already restricted access to COVID-19 vaccines, prompting medical associations to produce divergent recommendations, which raises a slew of unanswered questions about access to the vaccines.

Amid the standoff over rolling back vaccine policy, Kennedy urged Monarez to resign. She refused, and instead called key senators for help, including Bill Cassidy (R-La.), who cast a critical vote in favor of Kennedy’s confirmation in exchange for concessions that Kennedy would not upend CDC’s vaccine recommendations.

Cassidy then called Kennedy, which angered the anti-vaccine advocate, who then chastised Monarez. The beleaguered director was then presented with the choice to resign or be fired. She continued to refuse to resign. On Wednesday evening, HHS wrote of her termination on X. But Monarez, speaking through her lawyers, reiterated that she would not resign and had not been notified of her termination. Late Wednesday night, her lawyers confirmed that White House officials had sent notification of termination, but she still refused to vacate the role.

“As a presidential appointee, senate confirmed officer, only the president himself can fire her,” her lawyers, Mark Zaid and Abbe Lowell said in a statement emailed to Ars Technica. “For this reason, we reject the notification Dr. Monarez has received as legally deficient and she remains as CDC Director. We have notified the White House Counsel of our position.”

On Thursday, the Post reported that the White House had already named a replacement. Jim O’Neill, currently the deputy secretary of HHS, is to be the interim leader of the CDC. O’Neill was previously a Silicon Valley investor and entrepreneur who became a close ally of Peter Thiel. He also worked as a federal official in the George W. Bush administration. During the COVID-19 pandemic, he was a frequent critic of the CDC, but at his Senate confirmation hearing in May, he called himself “very strongly pro-vaccine.”

Kennedy, meanwhile, went on Fox News’ Fox and Friends program Thursday and said the CDC is “in trouble” and that “we’re fixing it. And it may be that some people should not be working there anymore.”

Kennedy’s ACIP is now scheduled to meet September 18–19 to discuss COVID-19 shots, among other vaccines.

Response at the CDC

Soon after news broke of Monarez’s removal, three high-ranking CDC officials resigned together: Daniel Jernigan, director of the National Center for Emerging Zoonotic Infectious Diseases; Debra Houry, chief medical officer; and Demetre Daskalakis, director of the National Center for Immunization and Respiratory Diseases.

Their resignation letters spoke to the dangers of Kennedy’s anti-vaccine, anti-science agenda.

“For the good of the nation and the world, the science at CDC should never be censored or subject to political pauses or interpretations,” Houry wrote in her resignation letter. “Vaccines save lives—this is an indisputable, well-established, scientific fact. … It is, of course, important to question, analyze, and review research and surveillance, but this must be done by experts with the right skills and experience, without bias, and considering the full weight of scientific evidence. Recently, the overstating of risks and the rise of misinformation have cost lives, as demonstrated by the highest number of US measles cases in 30 years and the violent attack on our agency.”

In his resignation letter, Daskalakis slammed Kennedy for his lack of transparency, communication, and interest in evidence-based policy. He accused the anti-vaccine advocate of using the CDC as “a tool to generate policies and materials that do not reflect scientific reality and are designed to hurt rather than to improve the public’s health.” He also blasted ACIP’s COVID work group members as having “dubious intent and more dubious scientific rigor.”

“The intentional eroding of trust in low-risk vaccines favoring natural infection and unproven remedies will bring us to a pre-vaccine era where only the strong will survive and many if not all will suffer,” Daskalakis wrote. “I believe in nutrition and exercise. I believe in making our food supply healthier, and I also believe in using vaccines to prevent death and disability. Eugenics plays prominently in the rhetoric being generated and is derivative of a legacy that good medicine and science should continue to shun.”

In a conversation with The New York Times published Friday, Daskalakis revealed that Kennedy has never accepted a briefing from his center’s experts and said the resignations should indicate that “there’s something extremely wrong [at CDC].

“And also I think it’s important for the American public to know that they really need to be cautious about the recommendations that they’re hearing coming out of ACIP,” he added.

As the three leaders were escorted out of the CDC on Thursday, the staff held a boisterous rally to show support for them and their agency. On his way out, Jernigan, who worked at CDC for more than 30 years, praised his colleagues.

“What makes us great at CDC is following the science, so let’s get the politics out of public health,” he said to cheers. “Let’s get back to the objectivity and let the science lead us, because that’s how we get to the best decisions for public health.”

While those three resignations made news on Wednesday and Thursday, they are part of a steady stream of exits from the agency since Kennedy became secretary. Earlier on Wednesday, Politico reported that Jennifer Layden, director of the agency’s Office of Public Health Data, Surveillance, and Technology, had also resigned.

Response outside the CDC

Lawmakers have expressed concern and even outrage over Monarez’s firing and what’s going on at the CDC.

Sen. Bernie Sanders (I-Vt.) quickly demanded a bipartisan investigation into Monarez’s firing, calling Kennedy’s actions “reckless” and “dangerous.”

He went on to blast Kennedy’s work as health secretary. “In just six months, Secretary Kennedy has completely upended the process for reviewing and recommending vaccines for the public,” Sanders said. “He has unilaterally narrowed eligibility for COVID vaccines approved by the FDA, despite an ongoing surge in cases. He has spread misinformation about the safety and effectiveness of vaccines during the largest measles outbreak in over 30 years. He continues to spread misinformation about COVID vaccines. Now he is pushing out scientific leaders who refuse to act as a rubber stamp for his dangerous conspiracy theories and manipulate science.”

Sanders called on Cassidy, chair of the Senate Health, Education, Labor, and Pensions (HELP) Committee, to immediately convene a public hearing with Kennedy and Monarez.

Cassidy called for the upcoming ACIP meeting to be postponed.

“Serious allegations have been made about the meeting agenda, membership, and lack of scientific process being followed for the now announced September ACIP meeting,” Cassidy said in a statement. “These decisions directly impact children’s health and the meeting should not occur until significant oversight has been conducted. If the meeting proceeds, any recommendations made should be rejected as lacking legitimacy given the seriousness of the allegations and the current turmoil in CDC leadership.”

Outside health organizations also expressed alarm about the situation at the CDC.

The American Medical Association said it was “deeply troubled” by the agency’s turmoil and called Monarez’s ouster and the other resignations “highly alarming at a challenging moment for public health.”

In a joint press conference on Thursday of the Infectious Disease Society of America and the American Public Health Association, leaders for the groups spoke of the ripple effects in the public health community and the American public more broadly.

“When leadership decisions weaken the CDC, every American becomes more vulnerable to outbreaks, pandemics, and bioterror threats,” Wendy Armstrong, vice president of the Infectious Disease Society of America said in the briefing. “We’re speaking out because protecting public health is our responsibility as physicians and scientists. It’s imperative that the White House and Congress take action to ensure a functioning CDC as the current HHS Secretary Robert Kennedy has failed.”

Georges Benjamin, executive director of the American Public Health Association, echoed the call, saying, “We’ve had enough.”

CDC director has been ousted just weeks after Senate confirmation

CDC, health, Monarez, robert f kennedy jr / Rejus Almole / August 28, 2025

Georges Benjamin, executive director of the American Public Health Association, told the outlet that Monarez “values science, is a solid researcher, and has a history of being a good manager. We’re looking forward to working with her.”

A low point for the agency

The reported ouster comes at what feels like a nadir for the CDC. The agency has lost hundreds of staff from layoffs and buyouts. Vital health programs have been shuttered or hampered. Dangerous rhetoric and health misinformation from Kennedy and other health officials in the Trump administration have made once-respected CDC experts feel vilified by the public and like targets of hate. Kennedy himself has falsely called the COVID-19 shots the “deadliest vaccine ever made” and the CDC a “cesspool of corruption,” for example.

On August 8, a gunman warped by vaccine disinformation opened fire on the CDC campus. Of nearly 500 shots fired, about 200 struck six CDC buildings as terrified staff dove for safety. One local police officer was killed in the incident. The gunman had specifically targeted the CDC for the shooting and blamed COVID-19 vaccines for his health problems.

Additional exits reported

After news broke of Monarez’s removal, Stat News reported that a wave of CDC leadership has resigned. The high-ranking resignations include: Daniel Jernigan, director of the National Center for Emerging Zoonotic Infectious Diseases; Deb Houry, Chief Medical Officer; and Demetre Daskalakis, director of the National Center for Immunization and Respiratory Diseases.

“I am not able to serve in this role any longer because of the ongoing weaponization of public health,” Daskalakis said in a message to staff seen by Stat.

“I am committed to protecting the public’s health, but the ongoing changes prevent me from continuing in my job as a leader of the agency,” Houry wrote in a message to staff. Houry added that science should “never be censored or subject to political interpretations.”

Earlier today, Politico reported that Jennifer Layden, director of the agency’s Office of Public Health Data, Surveillance, and Technology, has also resigned.

8/27/2025 8: 15 pm ET: This post has been updated to include the social media post from HHS, reporting from the Washington Post on the circumstances around Monarez’s exit, additional resignations reported by Stat and Politico, and the statement from Monarez’s lawyers.

CDC slashed food safety surveillance, now tracks only 2 of 8 top infections

CDC, food safety, foodborne, foodnet, health, infections / Tim Belzer / August 28, 2025

In July, the Centers for Disease Control and Prevention dramatically, but quietly, scaled back a food safety surveillance system, cutting active tracking from eight top foodborne infections down to just two, according to a report by NBC News.

The Foodborne Diseases Active Surveillance Network (FoodNet)—a network of surveillance sites that spans 10 states and covers about 54 million Americans (16 percent of the US population)—previously included active monitoring for eight infections from pathogens. Those include Campylobacter, Cyclospora, Listeria, Salmonella, Shiga toxin-producing E. coli (STEC), Shigella, Vibrio, and Yersinia.

Now the network is only monitoring for STEC and Salmonella.

A list of talking points the CDC sent the Connecticut health department (which is part of FoodNet) suggested that a lack of funding is behind the scaleback. “Funding has not kept pace with the resources required to maintain the continuation of FoodNet surveillance for all eight pathogens,” the CDC document said, according to NBC. The Trump administration has made brutal cuts to federal agencies, including the CDC, which has lost hundreds of employees this year.

A CDC spokesperson told the outlet that “Although FoodNet will narrow its focus to Salmonella and STEC, it will maintain both its infrastructure and the quality it has come to represent. Narrowing FoodNet’s reporting requirements and associated activities will allow FoodNet staff to prioritize core activities.”

Horrifying screwworm infection confirmed in US traveler after overseas trip

health, infection, larvae, Maryland, parasites, screw worms, texas / Paul Patrick / August 26, 2025

Flesh-eating screwworm larvae poised to invade the US have snuck into Maryland via the flesh of a person who had recently traveled to El Salvador, upping anxiety about the ghastly—and economically costly—parasite.

Reuters was first to report the case early Monday, quoting Andrew Nixon, spokesperson for the US Department of Health and Human Services, who said in an email that the Centers for Disease Control and Prevention had confirmed the case on August 4 in a person who had returned from a trip to El Salvador.

While other outlets have since reported that the screwworm case found in Maryland is the first human case in the US, or first travel-related case in the US, or the first case in years—none of those things are true. Screwworms are endemic in parts of South America and the Caribbean and travel-related cases have always been a threat and occasionally pop up in the US. While the CDC doesn’t keep a public tally of the cases, experts at the agency have noted several travel-related human cases in the US in recent years, including one as recent as last year.

The new case in Maryland doesn’t change anything in the US. “The risk to public health in the United States from this introduction is very low,” Nixon wrote to Reuters. But, what has changed is that the risk of an incursion at the US-Mexico border is no longer low—in fact it’s rather high currently.

Savage parasites

Screwworms were once endemic to the US before a massive eradication effort that began in the 1950s drove the population out of the US and Central America. The flies were held at bay with a biological barrier of constant releases of sterile male flies along the Darién Gap at the border of Panama and Colombia. The flies were declared eradicated from Panama in 2006. But, in 2022, the barrier was breached and the flies have worked their way back up through Central America, including El Salvador, since then. Now they are merely 370 miles or less from the Texas border, and state and federal agencies are preparing for an invasion, including with plans to build a sterile fly facility in the state.

Two men fell gravely ill last year; their infections link to deaths in the ’80s

CDC, Georgia, health, hurricane helene, Infectious disease, melioidosis, soil bacterium / Mike M. / August 23, 2025

Doctors soon discovered they were infected with the rare soil bacterium, which causes a disease called melioidosis.

Dangerous infection

Generally, melioidosis can be difficult to diagnose and tricky to treat, as it is naturally resistant to some antibiotics. It can infect people if they breathe it in or get it into open cuts. Sometimes the infection can stay localized, like a lung infection or a skin ulcer. But it can also get into the blood and become a systemic infection, spreading to various organs, including the brain. Fatality rates can be as high as 90 percent in people who are not treated but fall to less than 40 percent in people who receive prompt, proper care.

Both men in 2024 were quickly hospitalized and diagnosed with sepsis. Both were treated with heavy antibiotic regimens and recovered, though patient 2 relapsed in November, requiring another hospital stay. He ultimately recovered again.

According to the CDC, about a dozen melioidosis cases are identified each year in the US on average, but most occur in people who have traveled to areas known to harbor the bacterium. Neither of the men infected last year had recently traveled to any such places. So the researchers turned to genetic sequencing, which revealed the link to two cases in the 1980s.

In those cases, both men died from the infection. The man dubbed Patient 3 died in October of 1989. He was a veteran who fought in Vietnam—where the bacterium is endemic—two decades prior to his infection. The researchers note that such a long latency period for a B. pseudomallei infection is not entirely out of the question, but it would be rare to have such a large gap between an exposure and an infection. More suspiciously, the researchers note that in the month prior to Patient 3’s death, Hurricane Hugo made landfall in Georgia as a Category 4 storm, dumping three to five inches of rain.

America’s fragile drug supply chain is extremely vulnerable to climate change

health, hurricane helene, medical supply chain, natural disaster, supply chain shortages, supply chains / Kris Guyer / August 21, 2025

Vulnerabilities

Using data from the Food and Drug Administration, the researchers identified 10,861 drug facilities that were active for at least one year between 2019 and 2024. These facilities represent the array of manufacturing stages of a drug, from analyzing raw drug materials, to manufacturing active ingredients, to packaging drug products. The researchers then looked at the county location of each of these facilities and whether any federally declared weather emergencies occurred in those counties during the period. Weather-related emergencies included those from fires, hurricanes, storms, tornadoes, and floods.

During the six-year span, 6,819 facilities (63 percent) faced at least one weather-related emergency. Per year, an average of 2,146 facilities (33 percent) experienced such an emergency.

The researchers noted that there was no statistically significant difference in the likelihood that counties with or without a drug facility would experience a weather-related emergency. That is, it’s not the case that drug facilities have been built in areas uniquely vulnerable to climate-related disasters.

Still, with a third of US facilities at risk of weather disasters each year, the study clearly shows how fraught it is to have flimsy supply chains—like having a single plant produce 60 percent of the country’s supply of an essential drug product.

“These findings underscore the importance of recognizing climate-related vulnerabilities and the urgent need for supply chain transparency, for strategic allocation of production, and for disaster risk management strategies to prevent health care disruptions in the US,” the authors conclude.

Top pediatricians buck RFK Jr.’s anti-vaccine meddling on COVID shot guidance

aap, american academy of pediatrics, anti-vaccine, CDC, childhood vaccines, COVID-19, COVID-19 vaccines, health, kennedy, robert f kennedy jr, vaccines / Paul Patrick / August 20, 2025

“It’s clear that we’re in a different place in the pandemic than we were four or five years ago in terms of risks to healthy older kids,” Sean O’Leary, chair of the AAP Committee on Infectious Diseases (COID), said in a statement. However, “the risk of hospitalization for young children and those with high-risk conditions remains pretty high.”

According to CDC data, the rate of COVID-19 hospitalization in children under 2 is the highest among any pediatric group. Further, the rate of hospitalization among children 6 months to 23 months is comparable to that of adults ages 50 to 64. Critically, more than half of children ages 6 months to 23 months who are hospitalized for COVID-19 have no underlying medical condition that puts them at high risk for severe infection.

For children 2 to 18, the AAP recommends COVID-19 shots for children who have a medical condition that puts them at high risk, are residents of care facilities, have never been vaccinated, or have household contacts who are at high risk of severe COVID-19. All other children and teens should also have access to updated seasonal shots if they desire them, the AAP says.

“The AAP will continue to provide recommendations for immunizations that are rooted in science and are in the best interest of the health of infants, children, and adolescents,” Kressly said. “Pediatricians know how important routine childhood immunizations are in keeping children, families, and their communities healthy and thriving.”

Coverage questions

With school starting, COVID-19 cases ticking up around the country, and cold-weather respiratory virus season looming, the question now is how the conflicting recommendations will be interpreted by insurance companies. Insurers are required to cover vaccines recommended by the CDC. But there is no such obligation for recommendations from medical groups.

AAP has been holding meetings with insurers to press for continued coverage of evidence-based vaccine recommendations.

O’Leary told The Washington Post that insurers are “signaling that they are committed to covering our recommendations.” The Post also noted that AHIP, the major insurance lobby, released a statement in June saying its members are committed to “ongoing coverage of vaccines to ensure access and affordability for this respiratory virus season.”

The West Texas measles outbreak has ended

health, measles, measles outbreak, syndication / Tim Belzer / August 20, 2025

A large measles outbreak in Texas that has affected 762 people has now ended, according to an announcement Monday by the Texas Department of State Health Services. The agency says it has been more than 42 days since a new case was reported in any of the counties that previously showed evidence of ongoing transmission.

The outbreak has contributed to the worst year for measles cases in the United States in more than 30 years. As of August 5, the most recent update from the Centers for Disease Control and Prevention, a total of 1,356 confirmed measles cases have been reported across the country this year. For comparison, there were just 285 measles cases in 2024.

The Texas outbreak began in January in a rural Mennonite community with low vaccination rates. More than two-thirds of the state’s reported cases were in children, and two children in Texas died of the virus. Both were unvaccinated and had no known underlying conditions. Over the course of the outbreak, a total of 99 people were hospitalized, representing 13 percent of cases.

Measles is a highly contagious respiratory illness that can temporarily weaken the immune system, leaving individuals vulnerable to secondary infections such as pneumonia. In rare cases, it can also lead to swelling of the brain and long-term neurological damage. It can also cause pregnancy complications, such as premature birth and babies with low birth weight. The best way to prevent the disease is the measles, mumps, and rubella (MMR) vaccine. One dose of the vaccine is 93 percent effective against measles while two doses is 97 percent effective.

RFK Jr.’s Wi-Fi and 5G conspiracies appear to make it into MAHA report draft

5G, health, MAHA, robert f kennedy jr, trump administration, vaccines, wi-fi / Mike M. / August 19, 2025

The Trump administration’s plans to improve Americans’ health will include a push to review the safety of electromagnetic radiation, echoing long-held conspiracy theories and falsehoods about Wi-Fi and 5G touted by health secretary and anti-vaccine advocate Robert F. Kennedy Jr.

On Friday, Politico obtained a draft version of the “Make Our Children Healthy Again Strategy,” a highly anticipated report from the Make America Healthy Again (MAHA) Commission intended to steer the administration’s health policy. The report, which has not been adopted by the White House, is being viewed as friendly to industry, and it contains little to no policy recommendations or proposed regulations. For instance, it includes no proposed restrictions on pesticides or ultra-processed foods, which are top priorities of the MAHA movement.

Otherwise, the document mainly rehashes the talking points and priorities of Kennedy’s health crusades. That includes attacking water fluoridation, casting doubt on the safety of childhood vaccines, pushing for more physical activity in children to reduce chronic diseases, getting rid of synthetic food dyes, and claiming that children are being overprescribed medications.

Notably, the report does not mention the leading causes of death for American children, which are firearms and motor vehicle accidents. Cancer, another top killer, is only mentioned in the context of pushing new AI technologies at the National Institutes of Health. Poisonings, another top killer, are also not mentioned explicitly.

While the importance of water quality is raised in the report, it’s only in the context of fluoride and not of any other key contaminants, such as lead or PFAS. And although the draft strategy will prioritize “whole, minimally processed foods,” it offers no strategy for reducing the proportion of ultra-processed food (UPF) in Americans’ diets. The strategy merely aims to come up with a “government-wide definition” for UPF to guide future research and policies.

Anti-vaccine RFK Jr. creates vaccine panel of anti-vaccine group’s dreams

anti-vaccine, childhood vaccines, health, mRNA, robert f kennedy jr, vaccines / Kris Guyer / August 16, 2025

Immediate concern

It’s possible that Kennedy did not immediately set up the task force because the necessary leadership was not in place. The 1986 law says the task force “shall consist of consist of the Director of the National Institutes of Health, the Commissioner of the Food and Drug Administration, and the Director of the Centers for Disease Control [and Prevention].” But a CDC director was only confirmed and sworn in at the end of July.

With Susan Monarez now at the helm at CDC, the Department of Health and Human Services said Thursday that the task force is being revived, though it will be led by the NIH.

“By reinstating this Task Force, we are reaffirming our commitment to rigorous science, continuous improvement, and the trust of American families,” NIH Director Jay Bhattacharya said in the announcement. “NIH is proud to lead this effort to advance vaccine safety and support innovation that protects children without compromise.”

Kennedy’s anti-vaccine group cheered the move on social media, saying it was “grateful” that Kennedy was fulfilling his duty.

Outside health experts were immediately concerned by the move.

“What I am concerned about is making sure that we don’t overemphasize very small risks [of vaccines] and underestimate the real risk of infectious diseases and cancers that these vaccines help prevent,” Anne Zink, Alaska’s former chief medical officer, told The Washington Post.

David Higgins, a pediatrician and preventive medicine specialist at the University of Colorado Anschutz Medical Campus, worried about eroding trust in vaccines, telling the Post, “I am concerned that bringing this committee back implies to the public that we have not been looking at vaccine safety. The reality is, we evaluate the safety of vaccines more than any other medication, medical intervention, or supplements available.”

Paul Offit, a vaccine expert at Children’s Hospital of Philadelphia, worried about a more direct attack on vaccines, telling CNN, “Robert F. Kennedy Jr. is an anti-vaccine activist who has these fixed, immutable, science-resistant beliefs that vaccines are dangerous. He is in a position now to be able to set up task forces like this one [that] will find some way to support his notion that vaccines are doing more harm than good.”

Bat colony checks in to hotel; 200 guests check out, unaware of rabies scare

bats, Exposure, health, infectious, rabies, risk, wyoming / Paul Patrick / August 13, 2025

Health officials in Wyoming are sinking their teeth into a meaty task.

Over 200 people who stayed in a hotel in Grand Teton National Park between May and July may have unknowingly been exposed to rabies, according to Wyoming Public Radio.

In an announcement on Friday, the National Park Service reported finding evidence of a bat colony in the attic. The discovery was made after there had been at least eight incidents in which guests encountered winged mammals inside the hotel.

Now, the Wyoming Health Department is trying to contact all guests who stayed in a block of rooms under the bat’s lair. Specifically, they’re reaching out to the over 200 who stayed in rooms 516, 518, 520, 522, 524, 526, 528, and 530 at the Jackson Lake Lodge between May 15 and July 27. It was on July 27 that the eighth bat run-in occurred and the hotel closed the eight rooms.

“Although there were a lot of people exposed in this incident, one positive about it is that we know who 100 percent of those people are,” Travis Riddell, director of the Teton County Public Health Department, told Wyoming Public Radio.

In Wyoming, bats are one of the two main carriers of rabies, the other being skunks. But bats are of particular concern because—unlike an extremely obvious skunk attack—people might not be aware of bat exposures.

Inconspicuous risk

The rabies virus generally transmits through saliva via bites and scratches, and bat bites and scratches are easy to miss. The most common bat in Wyoming is the small brown bat, which weighs less than half an ounce on average—though they can look larger due to their wide wings. These teeny bats, with their wee teeth, can leave bites and scratches that are not visible, do not bleed, and are not painful.

Worm invades man’s eyeball, leading doctors to suck out his eye jelly

eyeball, eyes, health, infection, parasites, worms / Kris Guyer / August 13, 2025

For eight months, a 35-year-old man in India was bothered by his left eye. It was red and blurry. When he finally visited an ophthalmology clinic, it didn’t take long for doctors to unearth the cause.

In a case report in the New England Journal of Medicine, doctors report that they first noted that the eye was bloodshot and inflamed, and the pupil was dilated and fixed. The man’s vision in the eye was 20/80. A quick look inside his eye revealed it was all due to a small worm, which they watched “moving sluggishly” in the back of his eyeball.

To gouge out the parasitic pillager, the doctors performed a pars plana vitrectomy—a procedure that involves sucking out some of the jelly-like vitreous inside the eye. This procedure can be used in the treatment of a variety of eye conditions, but using it to hoover up worms is rare. In order to get in, the doctors make tiny incisions in the white parts of the eye (the sclera) and use a hollow needle-like device with suction. They replace extracted eye jelly with things like saline.

In this case, the device was able to suck in part of the worm’s tail and drag it out—still squirming. Under the microscope, they quickly identified the peeper creeper. With a bulbous head, well-formed intestines, and a thick outer layer, it perfectly fit the description of Gnathostoma spinigerum, a known bodily marauder that can sometimes wiggle its way into eyeballs.

Stomach-churning cycle

G. spinigerum are endemic parasites in India that infect carnivorous mammals, particularly wild and domestic cats and dogs. In these primary hosts, adult worms form tumor-like masses on the walls of the animals’ intestinal tracts. There, the adults mate, and the mass erupts like an infernal, infectious volcano, spewing out eggs. The eggs are passed in the animals’ feces and can then spread to intermediate hosts. These include freshwater plankton, which get eaten by fish and amphibians, which then get eaten by the cats and dogs to complete the cycle. The young parasites can also be taken up by dead-end hosts like birds, including chickens, and snakes—these are called paratenic hosts.
