    3. When Disinfection Falls Short: Examining Dilution, Technique, and Accountability

    A disinfectant dispenser that delivers the wrong concentration, shared equipment without clear cleaning responsibility, or restricted areas inaccessible to environmental services can expose gaps in environmental hygiene programs. In this interview with Infection Control Today® (ICT®), Doe Kley, MPH, RN, T-CHEST, LTC-CIP, CIC, discusses disinfectant efficacy, practical cleaning challenges, and shared accountability. Drawing on research and infection prevention experience, she emphasizes that everyday practices matter in addressing antimicrobial resistance. “Everyone has a role in preventing transmission,” Kley says. “Effective environmental hygiene isn't a supporting role in this fight - it's a frontline intervention.” ICT: You open by saying the post-antimicrobial era "isn't coming, it's here." For someone outside health care, what does that look like day-to-day? And what convinced you that it's already happening rather than a future risk?Doe Kley, MPH, RN, T-CHEST, LTC-CIP, CIC, infection prevention fellow of clinical and scientific affairs for Clorox Purell ProCare: That's the CDC's language, not mine—and I use it because the data backs it up. You know, resistance is rising faster than we can answer it. In the last decade, only about 22 new antibiotics reached the market. In contrast, up to 50 new drugs are coming out each year for things like diabetes, depression, and even weight loss.  Meanwhile, antibiotic resistance climbed nearly 40% between 2018 and 2023. Did you know that in the US, 1 in 7 bacterial infections is now resistant, costing about 48,000 lives and $5.7 billion a year? And what’s scarier is that by the year 2050, experts predict that AMR [antimicrobial resistance] will kill more people than all cancers combined. But what convinced me isn't the projection of AMR; it's the history. Methicillin came into widespread use in 1959, and the first resistant [Staphylococcus] appeared in 1960, just 1 year later. Consider that bacteria reproduce roughly every 20 minutes, whereas we humans only reproduce maybe twice in a lifetime. This replication speed is directly tied to how quickly antimicrobial resistance can emerge and spread. The math was never in our favor. What's at stake isn't just treating infections; it's whether surgery, transplants, and chemotherapy remain safe to perform. ICT: Most people hear "antibiotic resistance" and think about overprescribing. You argue that the hospital environment itself is half the story. How did you come to that view, and what do surfaces and shared equipment contribute that prescribing habits can't explain? DK: So antibiotic stewardship is essential, but it's only part of the solution, and here's what gets missed: Resistant organisms don't just live and replicate inside the patient’s body; they live and replicate on surfaces.  For perspective, a 2024 Rutala study found that 65% of resident rooms and half of common areas in long-term care facilities were positive for at least one MDRO [multidrug resistant organism]. Another 2024 study found that within just 4 hours of disinfection, Candida auris had already recontaminated 20% of surfaces. And the consequence is measurable: Being admitted to a room previously occupied by someone who harbored an MDRO raises the risk of acquiring that same organism by 1.5 to 3.5 times. Prescribing habits can't explain that. What prescribing also can't explain is gene sharing. While these organisms sit in the environment, they trade resistance genes with unrelated bacterial species. So, the environment isn't just a reservoir; it's where resistance spreads and evolves. Disinfectant #1 had no Klebsiella claim, and while disinfectant #2 (a ready-to-use sporicidal) had a Klebsiella claim, it did not have an NDM-1-specific claim. And that's the moment. People pause because neither disinfectant has the resistant strain on its label. That pause is the whole lesson. You don't need an NDM-1-specific claim. The claim for the susceptible strain covers the resistant one. And the sporicidal wipe wins on every other dimension too: broader spectrum, faster contact time, and no risk for dilution error. Audiences respond well because it's not abstract; they see the consequence play out. In the first path, the next patient admitted to the room acquires the NDM-1 pathogen. In the second path, the patient goes home in just 3 days with no complications. When participants make the choice themselves, it lands differently than when they are told the principle. ICT: You recommend a sporicidal disinfectant for every discharge clean, not just isolation rooms. That's a real workflow shift. How do you make that case to a skeptical hospital leader, and what evidence moves them?DK: I would start by defining the problem, which, in this case, is that we simply don’t know. Meaning, we don’t always know what pathogens a patient may have been harboring.  We only apply enhanced measures when we're aware a patient is carrying something, but all too often we are not aware until sometime later, and the damage is already done. In the scenario I used in this presentation, the patient wasn't even on contact precautions until the culture came back on the day of discharge. And that's not unusual. To convince my leadership, I would lean into the available evidence. I would point to the plethora of studies that have demonstrated the risk to the next patient admitted to a room previously occupied by a patient colonized or infected with a drug-resistant or a C difficile infection. These studies have demonstrated that the risk can be up to 3.5 times higher than had the prior occupant not been harboring a drug-resistant pathogen. Another study worth sharing is a 2019 Donskey study, which showed that when bleach replaced the quat for all discharge cleans, C difficile contamination in non-C difficile rooms dropped from 24% to 5%.   I would also share this important data that always gets a leader’s attention: the human and financial costs of AMR infections, which are associated with up to 70% higher mortality, up to 24% longer stays, and roughly 29% higher costs.  Finally, I would remind the leadership team that cleaning with a sporicidal agent is the highest level of clean you can offer the next patient admitted to a room. Remember, sporicidal disinfectants are considered intermediate-level disinfection—just 1 step below high-level disinfection and 1 step above low-level disinfection.  ICT: You shared a personal story that reminded participants not to overlook ancillary departments. Can you reshare that story here for us? Absolutely! At my last hospital, I had wandered down to Radiology, where MRIs are performed. As you know, this is a highly restricted area for safety reasons. You know, those magnets don’t play around! It's so restricted that I asked the radiology manager about cleaning. I learned they didn’t even permit EVS in the space! Rather, the radiology staff, untrained in C&D, were doing the cleaning! Guess how they mopped the floors? They dropped disinfecting wipes on the floor and shuffled around the room with their feet! Obviously, as an IP, this was completely unacceptable, so working together: •       We trained EVS staff on MRI safety,  •       We purchased non-ferrous aluminum cleaning tools that were dedicated to the department, and  •       We mapped out cleaning responsibilities. The key takeaway from this story is that IPs and EVS must look behind every door in every department! ICT: What's the one thing you'd want every EVS professional to hear from this: what's their role in preserving antibiotics for the next generation?DK: I want them to know how absolutely vital their role is in patient safety. You know, IPs and EVS professionals don't prescribe antibiotics — but they certainly help protect them. Every transmission prevented is potentially a life saved and an antibiotic preserved for someone who'll need it, possibly even years from now. Effective environmental hygiene isn't a supporting role in this fight - it's a frontline intervention working on 2 fronts: preventing infections so fewer antibiotics get used, and containing resistance so it doesn't reach the next patient.  (Edited for readability and length)

    The IFU Problem: Is Sterile Processing Information Becoming Unmanageable?

    Sterile Processing's Hidden Patient Safety Risk: When Cognitive Overload Meets Complex WorkSterile processing professionals perform high-stakes work requiring sustained attention to detail, yet burnout, fatigue, interruptions, and cognitive overload receive far less attention in SPD than in many patient-facing areas of health care. Randalyn Harreld, CRCST, CIS, CER, CHL, CSPDT, CASSPT, CLS, AAS, FHSPA, clinical education manager for Steelco Belimed, wants that to change. “This particular topic, I think, is pertinent and is not something that we talk about enough,” Harreld told Infection Control Today® following her presentation at the Southern California Sterile Processing Association chapter meeting in Newport Beach, California. “Because we're such a labor-intensive and hardworking environment, I just felt like it's important to bring it up.”  One major concern is interruption. “We say, and I say this all the time, ‘I'm a multitasker, and I can multitask.’ And really, there's a study that talks about how humans, we're not multitasking; we're task switching,” Harreld said. Consider an employee assembling an implant tray with 200 components. After counting 40, the technician is interrupted and later returns to the tray. “You forgot where you were,” Harreld said. “Now we're introducing rework.” But cognitive demands are only increasing. Harreld pointed to the rapidly evolving complexity of medical devices and the IFUs sterile processing professionals must follow. Some instructions she has encountered contain more than 100 steps, while formatting and organization vary considerably among manufacturers. “Just the complexity of the information that we are expected to know is getting harder, is getting faster, is getting more, bigger and longer,” Harreld said. “But how are we making it easier, and are we making it achievable to adhere to?”  Harreld would like to see greater standardization of IFUs, comparing the concept with safety data sheets, where information appears in predictable sections. Meanwhile, facilities can address human factors now. Harreld suggested standardized workflows, protected safe zones, micro-rests, staff rotation, technology aids, checklists, better access to IFUs, and reinforced training. “If your staff is tired or burnt out, try to come up with some strategies,” she said. “Really support your team to make sure that they feel like they're getting the relief before you lose them and before you have an injury.”

    Lead Aprons May Represent an Overlooked Infection Prevention Blind Spot

    Reusable lead aprons have long been viewed as essential radiation protection for clinicians, but infection prevention experts say they may also represent an overlooked environmental hygiene challenge. During a recent Infection Control Today and Diagnostic Imaging roundtable, experts from infection prevention, perioperative services, and radiology discussed why lead garments often escape the scrutiny applied to other reusable equipment despite being used every day in patient care environments.  Moderator Tori Whitacre Martonicz, MA, opened the discussion by asking whether reusable lead aprons have simply been overlooked rather than proven to be low risk. That question shaped a conversation focused on contamination, inconsistent cleaning practices, and the need for clearer guidance. Peter Graves, BSN, RN, CNOR, argued that lead garments should not be dismissed simply because they are covered by sterile gowns during procedures. "We don't go back and culture the lead ever," Graves said. "When we think about radiation-attenuating devices, lead actually functions much like PPE." Several panelists pointed to the absence of standardized cleaning protocols as a significant barrier. Jill Holdsworth explained that organizations may document cleaning activities, but there is often little consistency in how those garments are actually disinfected. Justin McKay said ATP testing has proven to be one of the most effective ways to demonstrate the problem. In one comparison, he found lead garments in an operating room to be far more contaminated than a gas pump handle. "When infection prevention sees the data, they say, 'We cannot ignore this,'" McKay said. The discussion also addressed practical challenges, including uncertainty about which disinfectants are compatible with lead garments, conflicting manufacturer recommendations, and questions over whether individual clinicians or hospitals are responsible for maintaining embroidered personal garments. Brenna Doran, PhD, MA, ACC, CIC, AL-CIP, suggested that hospitals would benefit from a practical implementation guide. "I would love there to be a playbook that IPs can go to," she said. "It's so much easier to do something someone else has done successfully than to create the wheel on our own." The panel concluded that addressing lead garment hygiene will require multidisciplinary collaboration and standardized protocols. As hospitals continue to strengthen environmental hygiene programs, experts believe reusable lead aprons should no longer be an infection prevention blind spot.

    AIDS 2026 Research Shows Individualized HIV Treatment Is Shaping the Future

    New research presented at AIDS 2026 demonstrates that HIV treatment continues to evolve, with growing evidence supporting both simplified 2-drug regimens and long-acting injectable therapies designed to improve adherence and quality of life. Jean van Wyk, MD, chief medical officer at ViiV Healthcare, discussed with Infection Control Today®, said the expanding treatment landscape gives people living with HIV more choices than ever before. "The important thing is clear communication and joint decision making," van Wyk said. "It's not for the physician to just decide what's best for the person sitting in front of them. It has to be a joint decision on what suits that person best." Among the studies presented was new data from the Long-Acting Treatment in Adolescents (LATA) trial, which found superior outcomes for long-acting injectable therapy compared with daily oral treatment in adolescents living with HIV. "Adherence is a real issue in adolescents," van Wyk said. "That's why long-acting injectables are a really good option for adolescents." He explained that injectable therapy removes the challenge of remembering to take a daily pill, while clinic-administered treatment results in consistently high adherence rates. Long-acting treatment may also help reduce HIV-related stigma because patients no longer need to keep medications at home or take pills every day. Beyond long-acting therapy, van Wyk highlighted the VOGUE study comparing the 2-drug regimen Dovato with the 3-drug regimen Biktarvy. The findings demonstrated comparable efficacy while potentially reducing patients' lifetime exposure to medications. Despite these advances, van Wyk emphasized that significant challenges remain. "We have great options, but why is it that between a quarter and a third of people around the globe do not have virologic suppression?" he said. "There's clearly a big unmet medical need still." Looking ahead, he remains optimistic that continued innovation, broader access to treatment, and stronger collaboration will help advance the global HIV response. "The whole model needs to be rethought," van Wyk said. "It is possible, and I'm always an optimist. I know we will get there. We just have to all work together."

    Contagious Conversations: One Profession, Many Pathways Into Infection Prevention

    Infection prevention and control (IPC) has long been recognized as a multidisciplinary field, yet the pathways into the profession vary dramatically across the globe. In the latest installment of Contagious Conversations, hosts Heather Stoltzfus, MPH, RN, CIC, and Brenna Doran, PhD, MA, ACC, CIC, AL-CIP, brought together 2 international infection prevention leaders to discuss how their countries educate, recruit, and support IPC professionals and what the future workforce may look like. Joining the discussion were Sinead Creedon, PhD, RGN, LLB, PCICP, MAAPP, director of the postgraduate certificate in infection prevention and control at University College Cork in Ireland, and Mohammed Halwani, PhD, professor, consultant, and infection control pioneer in Saudi Arabia. Together, they offered a fascinating look at how different health care systems approach the same mission: preventing infections and protecting patients. Both guests described unique journeys into infection prevention. Creedon began her career in infectious diseases and tropical medicine in London before returning to Ireland and transitioning into infection prevention. Halwani first became interested in IPC while pursuing graduate studies in medical microbiology in the United Kingdom, then completed additional training at Johns Hopkins Hospital and helped establish infection control programs throughout Saudi Arabia. Despite differences in geography and health care systems, both agreed that infection prevention has become increasingly complex, data-driven, and interdisciplinary. Traditionally, infection prevention roles in Ireland have been dominated by nurses. However, Creedon explained that modern IPC teams increasingly include microbiologists, pharmacists, surveillance scientists, and public health professionals. She noted that newer educational programs are also attracting professionals from diverse backgrounds, including veterinarians, physiotherapists, laboratory scientists, dental professionals, and public health specialists. "We've had a vet on our course because of the introduction of One Health," Creedon said. "We've had lab scientists, surveillance people, physiotherapists, [and] dental staff. It's really broad, and it's really nice to get all of those different people involved because each person brings a different flavor to the table." Halwani described a similar evolution in Saudi Arabia. While nurses continue to comprise many infection preventionists, professionals from microbiology, laboratory sciences, medicine, and public health are increasingly entering the field. He emphasized that public health professionals often contribute valuable expertise in epidemiology, statistics, and surveillance while receiving additional clinical training after joining IPC departments. The conversation quickly turned to a debate that has gained attention in the United States: Should infection prevention be reserved primarily for nurses, or should the profession actively recruit individuals from diverse disciplines? Both guests argued strongly for broader inclusion. Creedon believes the future of IPC depends on expanding opportunities for professionals with expertise in epidemiology, surveillance, behavioral science, quality improvement, and systems thinking. "IPC has become so scientific and data-driven," she said. "If we don't engage with that and if we're not able to do that, then we're just going to be left behind." She also highlighted the growing importance of behavioral science and patient safety competencies. "We've always had a role with quality patient safety. IPC and quality patient safety go hand in hand," Creedon said. Halwani offered an even more ambitious vision. Looking toward the future, he hopes universities will eventually establish dedicated bachelor's degrees in infection prevention and control. "I would love to see a bachelor’s degree in infection control," Halwani said. "You can teach some clinical nursing parts, microbiology parts, and then the public health and epidemiology part. If we did a 4- or 5-year program, that would be perfect." Such programs, he argued, would create professionals specifically trained for infection prevention from the start of their careers rather than requiring them to enter through nursing, microbiology, or public health pathways first. “That's an opportunity for us,” Doran said. “Many people who want to get into infection prevention, if they're not clinical or don't already work in a hospital, are dependent on someone taking a chance on them. Much of that training, that cross-training, happens internally within that department, and not all hospitals or departments have the bandwidth to provide the level of education and cross-training necessary. So, it sounds again like you're able to leverage this external, internal infection prevention training that allows people to get up to speed without really taxing the department.”  Another striking difference discussed during the conversation involved professional certification. While certification is highly valued in the United States, both guests noted that advanced academic degrees often carry greater weight within their healthcare systems. In Saudi Arabia, Halwani explained that certifications such as CIC are respected and common among infection preventionists, but master's degrees and doctoral education tend to be more influential when it comes to hiring and career advancement. Similarly, Ireland places significant emphasis on postgraduate qualifications, although new guidance from the European Centre for Disease Prevention and Control may eventually lead to broader certification frameworks across Europe. The panel also explored how the COVID-19 pandemic altered perceptions of infection prevention. Halwani described how the profession gained visibility and influence during the pandemic, leading more healthcare workers to pursue careers in IPC. "We actually had a stronger role in the hospitals, and people do respect infection control," he said. "After COVID, a lot of people wanted to do infection control." Throughout the discussion, a common theme emerged: there is no single path into infection prevention. Whether professionals arrive from nursing, microbiology, medicine, public health, epidemiology, pharmacy, or another discipline entirely, the field benefits from diverse perspectives. As healthcare becomes increasingly complex and data-driven, future infection prevention programs may need to embrace broader educational models and multidisciplinary teams to meet emerging challenges. As Stoltzfus noted during the conversation, the future of infection prevention will be shaped by professionals willing to learn from one another and build on their collective strengths. The more the global IPC community shares ideas, experiences, and approaches, the stronger the profession becomes. If this conversation demonstrated anything, it is that while infection prevention may look different from country to country, the commitment to patient safety remains universal. This conversation is part of the ongoing Contagious Conversations series exploring the future of infection prevention and control through diverse global perspectives.

    Dental PPE and Hand Hygiene: Avoiding the Most Common Infection Control Breaches

    Welcome Back to The Clean Bite!In May 2026, I had the honor of presenting an infection control class for just shy of 900 participants at the California Dental Association’s Art & Science Annual Meeting in Anaheim. I’m not going to lie, my biggest class ever. And the good news? I didn’t fall off the stage or throw up. So as far as this writer is concerned… huge success 😊 If you’ve ever had to “teach the experienced,” you know it can feel a little intimidating. But here’s the best part: I had a line of people waiting afterward and nearly 50 questions submitted through my Google form. That’s always my sign that it landed well: People felt comfortable, engaged, and curious enough to ask. Let’s Talk About the Real IssuesDuring the conference, my friend and fellow infection control enthusiast, Lori Serna-Pate, RDH, MEd, CDIPC, CEO and founder of Dental Training Solutions, and I sat down to discuss the most common infection control breaches we’re seeing. (You can catch the full conversation in the video!) Not surprisingly, personal protective equipment (PPE) usage rose right to the top, second only to hand hygiene. Let that sink in for a second. We’re either: Not using PPE at allUsing PPE as a uniform Or not removing it properly (like wearing clinical barriers outside treatment areas) And here’s the kicker: This isn’t isolated. It’s happening across the country in every type of dental setting. In Maryland and DC, where Lori works as a dental board inspector, the top 3 violations are: Lack of hand hygiene Improper PPE usage and disposal of PPE Failure to use utility gloves when handling sharps in the sterilization area Sound familiar? “When We Are at Risk”Lori made a statement that really stuck with me: “PPE is to be used when we are at risk, when we face occupational risk in our work setting.” Quick reality check: We are at risk in dentistry. Every single day. Even something as routine as treating a small cavity creates aerosols. That high-speed handpiece (aka…the “drill”) spins at incredible speeds, aerosolizing water and debris. Ultrasonic scalers do the same thing during hygiene visits. And those aerosols?They can travel up to 6 feet in any direction in the operatory. So yes, we suit up differently than our medical colleagues. PPE is chosen based on the risks faced in the work setting or during the activity to be performed. It’s essentially PPE-on-repeat all day long: Barriers (jackets or gowns) that cover the wrist, neck, and lap Exam gloves Masks Eye protection (safety glasses or face shields) Where We’re Falling ShortHere’s the truth: We’re pretty good about using gloves during patient care, but we struggle with: Hand hygiene before and after gloves Removing clinical barriers when leaving treatment areas Occupational Safety and Health Administration (OSHA) regulations and CDC guidelines are crystal clear: Hand hygiene must happen before donning and after doffing gloves. But what do we often do? Glove-to-glove transitions. No hand hygiene in between. Yes, this is a big deal. Offices have been fined $10,000 to $15,000 for a single violation. They are not playing around with this one. Now let’s talk about dental barriers (jackets/gowns). I’ll be honest; I used to wear mine everywhere: Front desk Bathroom Breakroom And I still see it all the time. Not because people don’t care, but because we’re busy and it’s easy to forget, or we just don’t know. The Overlooked Risk: Utility GlovesAnother big miss? Not using utility gloves when handling sharps and chemicals in the central sterilization area.Here’s something that may surprise you:About 90% of sharps injuries happen during instrument processing—not chairside. That’s exactly why OSHA mandates utility gloves. But here’s the reality in most offices: One size Shared by everyone (can you say gross here?) Poor fit for almost everyone Employer supplying dishwashing gloves instead of puncture and chemical resistant gloves. And when gloves don’t fit?They make instrument handling harder, not safer—especially when you’re dealing with burs, files, blades, cassette wraps, or pouch tape. A Simple Strategy That WorksLori and I also talked about workflow solutions, and one concept I absolutely love: Habit StackingThis means pairing a new habit with something you already do. For example: Perform hand hygiene while explaining the procedure to your patient Sanitize while asking, “Do you have any questions before we begin?” It’s simple, but incredibly effective. The Bottom LineHere’s what I want you to walk away with: Perform hand hygiene before and after glove use Remove jackets or gowns when leaving clinical areas Use properly fitting utility gloves when handling sharps and chemicals Make It Easy to Do the Right ThingA few quick wins for your practice: Create a team pact to remind each other about clinical barriers (jackets and gowns) Install hooks by operatory doors for easy removal and storage during the busy day Invest in multiple sizes of utility gloves, or better yet, assign personal pairs Small changes. Big impact. I’ve included the link to our full conversation above (and here again!) so you can dive deeper into the discussion. Because at the end of the day, staying on top of these fundamentals protects you, your team, and your patients and allows you to continue delivering the world-class care you’re known for. Until next time, my friends—Stay informed. Stay clean. Stay safe.🦷✨ — Sherrie, The Clean Bite

    Hantavirus: A Podcast with Matthew Pullen, MD, an Infectious Disease Doctor

    A rare hantavirus outbreak linked to an expedition cruise ship near South America has drawn international attention and renewed concerns about emerging infectious diseases. While experts emphasize that the risk of a widespread outbreak remains extremely low, the appearance of Andes virus-associated hantavirus pulmonary syndrome on a cruise ship has raised questions about global preparedness, travel-related transmission, and public understanding of infectious disease threats.A rare hantavirus outbreak linked to an expedition cruise ship near South America has drawn international attention and renewed concerns about emerging infectious diseases. While experts emphasize that the risk of a widespread outbreak remains extremely low, the appearance of Andes virus-associated hantavirus pulmonary syndrome on a cruise ship has raised questions about global preparedness, travel-related transmission, and public understanding of infectious disease threats. Matthew Pullen, MD, an infectious disease physician and member of the Infection Control Today® Editorial Advisory Board, said much of the concern stems from confusion about the virus itself. “Hantavirus is actually a very large family of viruses,” Pullen explained. “The ones we’re hearing about most right now are the Sin Nombre virus and Andes virus.” According to Pullen, Sin Nombre virus is the hantavirus most commonly found in the United States and is transmitted through infected deer mice. Andes virus, first identified in Argentina and Chile, has generated greater concern because of limited evidence suggesting possible human-to-human transmission. “There are a few cases where they’re pretty confident there was human-to-human transmission,” Pullen said. “But there’s still academic debate about whether some of those outbreaks represented true transmission or simply shared exposure.” Both viruses can cause hantavirus pulmonary syndrome, a severe disease with a case fatality rate approaching 40%. “It starts like a flu-like illness,” Pullen said. “Body aches, headaches, fever, nausea, vomiting. Then the severe cardiopulmonary phase develops, and that’s what kills people.” Despite the seriousness of the illness, Pullen stressed that fears of a COVID-19-like pandemic are unsupported by current evidence. “I would say the likelihood is very, very, very low,” he said. One reason is the virus's limited transmissibility. “It doesn’t spread like COVID[-19] does. It doesn’t spread like the flu does,” Pullen said. “The last estimate I saw had an R-naught of about 1.2, meaning not every case even propagates to another case.” Pullen also questioned whether current monitoring measures surrounding the cruise ship outbreak are sufficient. “While balancing public health with patient autonomy is important, there are still seemingly unanswered questions about the transmission and exposure events in this outbreak,” Pullen told Infection Control Today®. “This raises concerns about the current monitoring strategy, especially as compared to other nations that have repatriated citizens from the ship and are following tighter monitoring plans.” More than the virus itself, however, Pullen worries about the social environment surrounding emerging disease events. “What worries me most actually isn’t the virus itself,” Pullen said. “It’s the social conditions around the virus.” He pointed to rapidly changing narratives on social media. “One morning, people on social media were saying this was going to be the next pandemic that would kill us all,” he said. “By that afternoon, those same people were posting that hantavirus was nothing to worry about and that the government was lying.” Pullen also warned about individuals attempting to profit from public fear. “There was even a physician online promoting ivermectin as a cure for hantavirus,” Pullen said. “Then conveniently mentioning they also sell ivermectin.” For clinicians, awareness remains important despite the rarity of the disease. “If someone comes in with severe pulmonary syndrome after traveling through Argentina or Chile, that should absolutely bubble up in your mind,” he said. Pullen believes most US hospitals already have the infection prevention infrastructure necessary to manage suspected cases. “Every hospital should be equipped to do respiratory isolation and airborne precautions,” he said. “The key is recognizing the syndrome early and escalating appropriately.” Still, he expressed concern about broader public health capacity. “The people working at CDC are phenomenal,” he said. “But they’re being hamstrung by funding limitations and policy decisions.” Ultimately, Pullen said the outbreak serves as another reminder that emerging zoonotic diseases will remain a global challenge. “Viruses don’t respect borders,” he said. “And the more interconnected the world becomes, the more important preparedness, communication, and public trust become.”
