Hantavirus anxiety is testing the next phase of client trust

A new Veterinary Viewfinder discussion is using hantavirus as a case study in something larger: how fast-moving health fears, online misinformation, and post-pandemic skepticism can reshape what pet parents expect from veterinarians. In the episode, Dr. Ernie Ward and Beckie Mossor, RVT, connect concern about hantavirus to broader questions around science skepticism, vaccine hesitancy, and the future of client trust in practice. That framing resonates because veterinary medicine is already seeing evidence that trust, not just clinical recommendation, increasingly determines whether preventive care moves forward.

The hantavirus backdrop is clinically important, but specific. CDC says hantaviruses are spread mainly by infected rodents through urine, feces, and saliva, with exposure often linked to inhalation of contaminated particles during cleanup or infestation events. In the United States, dogs and cats are not known to become infected with hantavirus, although pets may bring infected rodents into the home. CDC also notes that hantavirus pulmonary syndrome can be severe, with a fatality rate of nearly 4 in 10 people who are infected, underscoring why public concern rises quickly when the virus enters headlines.

For veterinarians, though, the more relevant operational issue may be how these stories alter client behavior. The profession has been tracking spillover from human vaccine politics for several years. A 2023 study in Vaccine, cited in recent AVMA coverage, found that 52% of U.S. dog owners showed some degree of canine vaccine hesitancy. A 2025 JAVMA study found that 62.9% of dog owners and 61.2% of cat owners were classified as trusting their veterinarians, and that higher trust was associated with vaccination behavior and reliance on veterinarians as a primary information source.

That helps explain why organized veterinary medicine is now responding more directly. According to recent reporting, AVMA launched a new resource in January 2026 to help veterinarians address pet vaccine hesitancy and explain the value of vaccination to clients. The timing appears deliberate: earlier research in U.S. and Canadian veterinarians found that clinicians were already encountering clients who resisted vaccination because of cost concerns, low perceived need, or fears of chronic or severe illness, and that vaccine resistance tracked with broader anti-vaccine activity in the community.

Industry and clinical commentary points to a similar pattern. In AAHA’s 2025 coverage of vaccine hesitancy, Cheryl Roth, DVM, said pet parents may absorb misinformation from breeders, groomers, pet store employees, friends, and internet sources. Jordan Gagne, DVM, added that successful vaccination programs can paradoxically make disease risk feel remote, leading some clients to judge the perceived harms or costs of vaccination as greater than the risk of infection. AAHA’s guidance emphasizes a nonadversarial approach, arguing that trust is strengthened when teams frame the conversation around shared goals rather than debate. (aaha.org)

There is also a narrower hantavirus-related veterinary angle in rodents. CDC’s guidance for Seoul virus, a hantavirus carried by Norway rats, recommends serologic testing for exposed rats, heightened PPE and scheduling precautions for veterinary staff, and client education about human symptoms after exposure. Infected rats can pose a risk to people and other rats, and CDC recommends euthanasia of infected rats under AVMA-approved guidance. That means exotic and small mammal practices may face more direct workflow and biosafety questions than dog and cat clinics do. (cdc.gov)

Why it matters: The bigger lesson for veterinary professionals is that trust is becoming a clinical tool, not just a soft skill. When pet parents arrive with fears shaped by headlines, social feeds, or generalized distrust of institutions, the exam room becomes a place where zoonotic risk communication, preventive medicine, and relationship-building all happen at once. Hantavirus may not represent a new widespread companion animal disease threat in the U.S., but it does illustrate how quickly public anxiety can migrate into everyday practice, especially around vaccines, diagnostics, and perceived overreach. Practices that can explain uncertainty clearly, acknowledge concern without validating misinformation, and keep recommendations grounded in local risk and evidence may be better positioned to preserve both compliance and long-term trust.

What to watch: Expect more communication tools from AVMA, AAHA, and practice management voices, along with growing attention to how teams handle zoonotic disease questions, rodent-related exposures, and vaccine conversations as client skepticism evolves through 2026. (dvm360.com)
