Here's some good information about canine influenza from our friends at Animal Medical Hospital in Mason City. Thanks for sharing! ...
We've had a lot of questions about canine influenza over the last few days. Here's what we know:
-Canine influenza has been confirmed in Illinois, Wisconsin, and Indiana. Not yet in Iowa, but it seems inevitable.
-Dogs are infected and transmitting virus for approximately 4 days before they start showing signs of disease. Shortly after signs, virus shedding significantly decreases. (So just like in humans, dogs transmit the virus before anyone knows they are sick.)
-Signs of influenza disease in dogs are coughing (sometimes until vomiting), nasal discharge, and a fever.
-100% of dogs exposed will be infected, and 80% of dogs exposed will get sick. Current numbers indicate 2-5% mortality rate.
-There is a vaccine for canine influenza, H3N8 strain, but the current strain causing issue is H3N2. Studies are being performed currently to see if there is any cross-protection (ie-to see if the vaccine will help with the current outbreak).
-Canine influenza can be transmitted to your cats as well, but further testing is needed to determine if this virus can be transmitted to humans or other animals.
The best protection is avoidance! We may caution you to keep your dogs home from dog parks, pet stores and doggie daycares.
Early treatment is important! Please let us know if you have been traveling, if your dog has been in contact with other dogs that are ill, or if you have other reason to believe he/she has been exposed. We will likely suggest you keep your dog in the car or outside for the initial exam.
