Canine Influenza infection was identified in dogs attending dog shows in Perry, GA and DeLand, FL in late May 2017. It has not been reported in pet dogs in south Florida since this outbreak. Canine Influenza Virus (CIV), or dog flu, is a highly contagious respiratory infection of dogs that is caused by an influenza A virus. CIV causes mild disease in most dogs exposed. CIV can be spread by direct contact, airborne routes, or through contaminated objects or clothing.
The CIV vaccination is a "lifestyle" vaccination, recommended for dogs at higher risk such as dog shows, boarding, grooming, dog parks, and attending events with groups of dogs present. Vaccination may not prevent infection altogether, but can reduce the severity and duration of illness and decrease the spread of infection – similar to human influenza vaccination. Avoidance of exposure to other dogs is the best prevention.
