Highly Contagious Dog Flu Now Confirmed in 8 States

Just one week after a resurgence of the highly contagious dog flu, H3N2 was discovered Florida, the dangerous flu has now been confirmed in at least 8 states.

The University of Florida’s College of Veterinary Medicine named eight states that have confirmed current cases of the H3N2 dog flu. Those states are Florida, Georgia, South Carolina, North Carolina, Tennessee, Kentucky, Texas, and Illinois.

Canine influenza A H3N2, a type of bird flu that adapted with the ability to infect dogs first appeared in parts of Asia in 2007. In April of 2015, the first case of Canine H3N2 was found in the United States. Although it’s unknown how the virus made its way here, the outbreak first began in Illinois where an estimated 2,000 dogs were infected.

Over the next several weeks, the flu spread to surrounding states in the Midwest and made its way as far south as Alabama, Georgia, and Texas and as far west as California. For several months, it seemed as if the spread of the flu had been contained – until now.

The flu is spread from dog to dog (and now, to cats) much in the same way the human flu is spread – through direct contact, through coughing and sneezing, through contact with contaminated objects and surfaces, etc. Dogs infected may only show symptoms for about two weeks, but will remain contagious for four weeks.

In infected dog’s cough can spread the virus up to 20-feet in any direction. While the flu is not contagious to humans, the virus can live for 24-hours outside of a host, on surfaces including human clothing, floors, bedding, sidewalks, and any areas where an infected dog has had access. For these reasons, the flu is considered highly contagious and is very quickly spread over wide regions.

Researchers have traced the most recent cases of the dog flu to a dog show held in Perry, Georgia on May 19-21 and a Deland, Florida dog show the following weekend, and to any dog that came in (direct or indirect) contact with an infected dog.

The most common symptoms of H3N2 virus in dogs are runny nose, cough, and fever, but not all dogs will show symptoms.

In other words, your dog could appear to be perfectly healthy while carrying and infecting other dogs with the virus. Likewise, your dog could be infected by a dog that appears healthy.

If you’re living in an area where the dog flu has been confirmed, keep your dogs on leash and away from other dogs. Avoid dog parks, kennels, and doggie day care centers where dogs are in close proximity to one another or sharing toys and play surfaces.

Currently, a canine flu vaccine does exist, but it’s effectiveness against the H3N2 virus is not yet proven.

A test for the H3N2 virus has been developed and is available from a veterinarian. If your dog shows any signs of the flu or if you suspect he’s been exposed, immediately talk to your veterinarian.

Outbreak News Today urges dog owners suspecting dog flu to call their veterinarian prior to going to the clinic in order to decrease the chances of spreading the virus to other animals at the clinic. Many dogs have a fever, decreased appetite and lethargy during the first few days of illness.

Most dogs recover at home without any complications, but the flu has led to hospitalization and death in multiple dogs infected.
