Authorities Investigating Mysterious Parvo-Like Illness Affecting Dogs In Michigan

Authorities are investigating cases of parvo-like illnesses among dogs in northern Michigan. Pet owners are being encouraged to take extra precautions.

A veterinarian in northern Michigan alerted the Michigan Department of Agriculture and Rural Development (MDARD) about a dog that was vomiting and had diarrhea, the agency noted in a news release dated Aug. 19. These symptoms, the agency noted, are "common symptoms of canine parvovirus," which is a very contagious virus that can lead to the dog's death within 48 to 72 hours after the onset of clinical signs.

However, the dog reportedly tested negative for the virus, and the agency continued to receive reports of dogs with similar symptoms but undetermined illnesses.

In response, the agency, together with its partners, including local veterinarians, the U.S. Department of Agriculture and Michigan State University Veterinary Diagnostic Laboratory (MSU VDL), have been working together to investigate the cause of the illnesses.

The university noted in an update from MSU VDL Monday that investigations are ongoing and that some of the samples had turned out positive for canine parvovirus. They are currently conducting more tests.

"We are still in the early stages of this investigation, but some of the first samples submitted to the Michigan State University Veterinary Diagnostic Laboratory were positive for canine parvovirus. However, there are more results pending and more to be learned," Nora Wineland, state veterinarian, said in an update.

As such, authorities are urging veterinarians to pursue further testing if a dog presents with symptoms of parvovirus but tests negative for it. Pet owners are also being urged to take precautions by ensuring that their pets' vaccinations are updated. There is a "highly effective" vaccine against parvovirus.

"Protecting animal and public health is one of the department's key pillars, but it is a team effort," Wineland added. "Dog owners need to ensure their pet is up to date on routine vaccinations as it's the first step in keeping your pet healthy."

They should also make sure to clean up after their dog and not allow them to get in contact with other animal waste. It's also important to keep them away from other dogs if they are sick and to contact their veterinarian.

Those taking care of sick or exposed dogs should also either avoid contact with other dogs or "at least" wash their hands thoroughly and change their clothes before coming in contact with them, according to the American Veterinary Medical Association.

Authorities are stressing that canine parvovirus is "NOT contagious to people or other animals."
