Oregon State Veterinarian Reports Possible Feline Fatality From H1N1 Influenza
Dr. Eric Barchas, DVM

Breaking news.

This morning I received another H1N1 influenza (swine flu) action alert from the American Veterinary Medical Association (AVMA).

H1N1 update: Cat death in Oregon from presumed 2009 H1N1

November 18, 2009 – The Oregon state public health veterinarian has reported that a pet cat has died from presumed 2009 H1N1 influenza virus infection. The cat was one of 4 cats in the household and became ill approximately one week after a child in the household had a flu-like illness. It developed labored breathing and was presented to a veterinarian on November 4. The cat was not coughing or sneezing but had pneumonia. The cat’s condition deteriorated over the next 3 days, and it died on November 7. Samples were obtained and tested (PCR) positive for the 2009 H1N1 influenza virus. Additional samples were sent to the National Veterinary Services Laboratories (NVSL) for confirmation and are still pending. At this time this is a presumed, not confirmed, case of 2009 H1N1 influenza infection.

The three other cats in the household also became ill with different degrees of sneezing and coughing, but recovered from their illnesses. Samples collected from these cats were negative for the 2009 H1N1 influenza virus.

We continue to update our 2009 H1N1 influenza resources as soon as we receive and verify information. These resources are available at http://www.avma.org/public_health/influenza/new_virus/default.asp. We are also in the process of updating our “Frequently Asked Questions” document for veterinarians to include additional information about sampling and testing procedures, and anticipate the updated document will be posted within the next 24 hours. The document is linked from the H1N1 page or at http://www.avma.org/public_health/influenza/new_virus/new_flu_virus_faq_veterinarians.asp.

The messages to pet owners remain the same.

  • This is not cause for panic, but underscores the importance of taking pets to a veterinarian if they are showing signs of illness. This is especially important if someone in the household has recently been ill with flu-like symptoms.
  • Ferret and cat owners should remain vigilant.
  • To date, all of the sick pets became ill after a person in the household was ill with flu-like symptoms. There is no evidence to suggest that pets have or will spread the virus to humans or other animals.
  • Proper hygiene and sanitation measures should be followed to limit the spread of the influenza virus.
  • The web page mentioned in the action alert is a great resource for breaking developments in the matter of swine flu in pets. I recommend that you check it regularly if you are interested in the subject.

    Can Pets Catch Swine Flu?
    Dr. Eric Barchas, DVM

    3D_Influenza_virusSwine flu, also known as H1N1 influenza, has been dominating the news recently. The viral strain appears set to cause the first influenza pandemic in a generation. Influenza pandemics are big deals. The pandemic of 1918-1920 caused more people to die from flu than from bullets or bombs during World War One.

    Influenza viruses are known for infecting multiple species–as the name would imply, swine flu developed in pigs and then spread to people.

    This may lead pet owners to wonder: can cats and dogs catch swine flu?

    The answer appears to be no. DVM Newsmagazine reports that there is no evidence cats or dogs can contract, carry, spread, or suffer illness from H1N1 influenza.

    H1N1 influenza has been isolated from a ferret. Fortunately at this time there is no evidence that ferrets can spread the disease to people.

    Although it appears we can rest easy about our cats and dogs catching swine flu, remember that cats are susceptible to an even scarier form of influenza: bird flu (also known as H5N1). Cats contract bird flu by preying upon or being fed raw bird meat. The virus does not appear capable of spreading from cat to cat. That is a good thing, since the fatality rate among cats infected with H5N1 appears to be 100%.

    Fortunately, it is easy to protect your cat from H5N1. If you feed your cat commercial or cooked food and keep him indoors, his chances of catching bird flu are nil.

    How Common is Dog Flu?
    Dr. Eric Barchas, DVM

    cooperWhat and how high is the risk of your dog catching the Canine Flu, if you take them to a Dog Park?

    Also, when, where and how did this virus start?

    Thank you,

    Canine influenza was first identified in a Greyhound racing facility in Florida in January, 2004. It is suspected that equine influenza virus mutated and spread to dogs. (The ongoing swine flu pandemic is another example of influenza viruses jumping from one species to another.)

    Canine influenza caused a massive hullabaloo a few years ago. Many veterinarians worried that an epizootic (the animal equivalent of an epidemic) would occur, with unknown consequences for dogs the world over.

    Fortunately, the epizootic never developed, and canine influenza receded into obscurity.

    Canine influenza is a highly contagious disease that causes symptoms identical to kennel cough in most dogs. In other words, most dogs that contract the virus suffer mild symptoms that include coughing. Most individuals recover completely without veterinary intervention.

    However, a small minority of dogs (approximately 5% – 8%, according to the American Veterinary Medical Association’s canine influenza web page) suffer from fatal flu complications such as pneumonia.

    At this time, canine influenza does not appear to be common. The odds of a dog contracting the disease at the dog park are probably very low.

    However, influenza viruses have a knack for re-emerging after years of obscurity. It would not surprise me if, in the next several years, the dreaded epizootic were to materialize. If that happens, the dog park will be a prime place for the virus to spread.
