H1N1 Confirmed in a Dog

We must now add dogs to our list of domestic animals which can contract the H1N1 virus. The symptoms appear to be the same for all species; if you suspect your pet has the flu, please get him/her in to see your veterinarian.

The American Veterinary Medical Association reports:

December 21, 2009
IDEXX Laboratories has confirmed 2009 H1N1 influenza virus in a dog in Bedford Hills, New York. A 13-year old dog became ill after its owner was ill with confirmed 2009 H1N1 influenza. The dog was lethargic, coughing, not eating, and had a fever. Radiographs (x-rays) showed evidence of pneumonia. The dog was treated with intravenous fluids, antibiotics, nebulization and other supportive care, and was discharged from the hospital after 48 hours of care. It is currently recovering. Tests submitted to IDEXX Laboratories were negative for canine influenza (H3N8) but positive for 2009 H1N1 influenza. The results were confirmed by the Iowa State Laboratory.

Cat Death in Oregon from Presumed 2009 H1N1

From the CVMA eNews Digest 11.20.09

"On November 18, the Oregon state public health veterinarian reported that a pet cat died from presumed 2009 H1N1 influenza virus infection. The cat was one of four in the household and became ill approximately one week after a child in the household had a flu-like illness. The cat 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 three 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.

The AVMA continues to update its 2009 H1N1 influenza resources, which are available at http://www.avma.org/public_health/influenza/new_virus/default.asp including a “Frequently Asked Questions” document for veterinarians that includes additional information about sampling and testing procedures. 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."
