By now you've probably seen the headlines. The MV Hondius, a Dutch research vessel carrying 147 passengers and crew, departed Ushuaia, Argentina on April 1 and traveled through the South Atlantic, stopping at Antarctica, South Georgia Island, and several remote Atlantic islands. Somewhere along the way, multiple passengers were exposed to Andes virus, a hantavirus strain endemic to South America and carried by long-tailed pygmy rice rats in Patagonia. As of this writing, eight cases have been confirmed or suspected, three people have died, and WHO has dispatched its director-general to the Canary Islands to coordinate the ship's evacuation. The CDC is working to locate and monitor dozens of passengers who disembarked before the outbreak was identified.

Cats, dogs, and livestock are not reservoir hosts for hantavirus, and companion animals do not transmit the Andes strain to humans. If a client calls your clinic worried about their pet, you can reassure them. But the broader story has implications for our profession. Hantaviruses are zoonotic pathogens maintained in wild rodent populations, transmitted through aerosolized particles from rodent urine, feces, and saliva, and capable of causing severe pulmonary disease with a case fatality rate that can reach 40%. The only reason the Andes strain is worth watching beyond the usual hantavirus playbook is that it has documented human-to-human transmission, which is what has the epidemiological community paying close attention to this cluster. Seoul orthohantavirus, a different strain, has been found in pet rat breeding colonies in the US and Europe and has transmitted to owners. Veterinarians who see exotic or pocket pet species are an underappreciated link in detecting and counseling around that exposure risk.

World Veterinary Day was celebrated just two weeks ago, on April 25, under the theme "Veterinarians: Guardians of Food and Health." The World Veterinary Association chose that framing deliberately, to highlight the role the profession plays in safeguarding not just animal health but food safety, food security, and human public health. The hantavirus outbreak is a timely, if grim, illustration of exactly that premise.

Rodent surveillance, wildlife population monitoring, zoonotic disease detection, and the early warning systems that catch spillover events before they become crises, these are areas where veterinary training and veterinary infrastructure matter enormously.

The American Heartworm Society released its triennial incidence survey this month, and the headline that should get practitioners' attention is this: for the first time, the 2026 survey did not identify a single heartworm-free state. The survey, which drew on more than one million canine heartworm antigen tests from over a thousand practices and shelters, confirms what many practitioners in historically low-risk regions have already been noticing. The parasite is not staying where it used to live.

Texas has, for the first time, claimed the top spot nationally, with participating clinics averaging nearly 50 heartworm-positive dogs each, a rate of 3.78%, up from 2.97% in the 2022 survey. The usual Southern suspects round out the top ten: Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, and Tennessee. But the more striking data is at the edges. New moderate-infection areas, defined as six to 25 cases per clinic, have now been documented in southern California, southwest Colorado, east-central Wisconsin, western Virginia, and southern Maine. Cases have been confirmed in central Washington, northern Idaho, northwest Nevada, and southeast Wyoming, areas that previously reported fewer than one case per clinic. The drivers are familiar: infected coyotes expanding into urban areas, dog relocations from endemic regions through rescue networks, post-hurricane mosquito surges, and climate shifts lengthening transmission seasons. With heartworm present in every state, prevention conversations now belong in every wellness visit.

Minnesota Governor Tim Walz signed a new veterinary technician framework into law on April 29. As of July 1, anyone in the state using the title "veterinary technician" or "vet tech" must be licensed by the Minnesota Board of Veterinary Medicine or stop using the title. The new law clarifies remote supervision authority, broadens livestock management tasks LVTs can perform, and formalizes disciplinary and recordkeeping standards. It is good workforce policy, and it is the result of a decades-long push by the Minnesota VMA and the Minnesota Association of Veterinary Technicians that finally got across the finish line.

The Minnesota story matters beyond state lines because it is happening in the middle of a profession-wide argument about scope of practice and who fills the access gap. Eight states still have no regulation of veterinary technicians at all. Colorado just launched its first Veterinary Professional Associate program, a midlevel practitioner model that the AVMA, AAHA, NAVTA, and most state VMAs oppose. The VPA and the LVT are different instruments aimed at the same underlying problem: there are not enough credentialed veterinary professionals to meet demand, and something has to give. Minnesota's answer is to invest in the credentialed technician pipeline, extend their scope under appropriate supervision, and protect the title so it means something. That approach is less disruptive to the profession's existing structure, but it only works if practices actually deploy LVTs to the top of their training, which remains inconsistent. The VPA debate is not going away, and how well the technician-centered model performs over the next few years in states like Minnesota will directly shape whether the VPA argument gets harder or easier to make.
