![]() In March 2017, H3N2 canine influenza was identified in dogs in Los Angeles (LA) County. Most of the dogs were imported from Asia and seen by a veterinarian upon arrival into LA County. The dogs showed signs consistent with influenza such as coughing, sneezing, fever and nasal discharge. A total of 27 dogs were sick with the disease and treated with supportive care. Final testing of two dogs revealed a strain of canine influenza (H3N2) commonly found in Asia, further testing is pending. Most of the dogs have recovered. H3N2 canine influenza usually causes mild disease in dogs and on rare occasions can also infect cats. This strain of canine influenza was first found in the US in 2015 when it caused a large outbreak in the Chicago area that spread to other parts of the country. Infected dogs start shedding the the virus 2 days before the start of clinical signs (meaning the virus was "available" to other dogs if exposed), and for 21 days or longer afterward. Transmission of influenza usually occurs through contact with infected respiratory secretions (e.g. coughing, sneezing) as well as from contamination of the environment (e.g. bedding, floors, bowls, collars, leashes). |
