Update on the “bizarre” respiratory illness in dogs
Here is information that we have currently. We appreciate all your diligence and patience in this evolving situation.
How many reports of atypical respiratory disease has the WSDA receive
Since August 2023, a total of 16 reports from veterinarians have been submitted to the Washington State Department of Agriculture concerning atypical Canine Infectious Respiratory Disease Complex (CIRDC). Of those 16 reports, two cases have met what WA considers an atypical CIRDC case. The two confirmed cases are recovering. WSDA is still collecting more information on the other 14 reports to ensure we provide accurate information. The morbidity and mortality remains low, according to the reports provided to the state.
Are the cases regionally distributed?
At this time, half of the cases reported in the state are in King County, which may be consistent with urban population distribution. We did have an outbreak reported in a single animal rescue in Spokane County. Otherwise, we have not been able to link cases to each other.
County
Number of Reports
Clark. 1
Island. 2
King. 7
Pierce 1
Skamania 1
Snohomish. 1
Spokane. 3
Are laboratories seeing an uptick in cases?
WSDA works very closely with Washington Animal Disease Diagnostic Laboratory at Washington State University (WSU-WADDL) to be sure we are tracking submissions and diagnostics. At this time, WSU WADDL has not reported an uptick in case submissions to the laboratory. Case reports have identified various causes with no linking cause between cases. It is important to remember that there are many underlying causes of canine respiratory disease. We are continuing to encourage diagnostics to help us better understand trends.
Have dogs been tested for SARS-COV2 (COVID 19)?
Several laboratories across the United States are working diligently to try to isolate any new pathogen that may be implicated or any correlation with positive COVID 19 households. Although dogs can be susceptible to SARS COV 2, experts reported that so far, all the cases submitted have been negative.
What to do if you suspect a case?
There has been no official case definition provided to the states from the United States Department of Agriculture for atypical Canine Infectious Respiratory Disease Complex (CIRDC). However, WA has adopted the following case definition:
WA Case Definition:
· Negative Canine Infection Respiratory Disease (CIRD) diagnostic panel.
o Panel should include diagnostics for:
§ Bordetella bronchiseptica, canine adenovirus 2, canine distemper virus, canine herpesvirus 1, canine influenza virus (subtypes H3N8 and H3N2), canine respiratory coronavirus, and canine parainfluenza virus, all by real time PCR.
o If the panel is negative:
· And the patient has displayed any of the below clinical syndromes:
o Chronic mild-moderate tracheobronchitis with a prolonged duration (6-8 weeks or longer) that is minimally or not responsive to antibiotics.
o Chronic pneumonia that is minimally or not responsive to antibiotics.
o Acute pneumonia that rapidly becomes severe and often leads to poor outcomes in as little as 24-36 hours
As of right now, there is no funding to pay for CIRD diagnostic panels.
