Contagious, deadly dog virus detected at Ft. De Soto Park after 3 raccoons test positive for distemper

ST. PETERSBURG, Fla. - Pinellas County officials are out with an alert for pet owners regarding the discovery of the highly contagious canine distemper virus at Ft. De Soto Park Campground. 

The alert took effect on Wednesday, Jan. 10, confirming the presence of the virus on the county's online campsite reservation system. 

Pinellas County officials say the outbreak stems from infected raccoons at the campground. 

Chief ranger Dave Harshbarger said three raccoons were reportedly displaying seizure-like symptoms and were sent away from distemper testing this week. An additional raccoon was also found showing the same symptoms. 

This isn't the first time raccoons tested positive for distemper at the park. There was a distemper outbreak at Ft. De Soto in January 2019 when animal services found infections in multiple raccoons at the park.

"Distemper is a highly contagious disease spreading quickly among dogs," the alert said. "It has the potential to kill dogs that have not been vaccinated or are susceptible for reasons of age or compromised immune system." 

A dangerous dog virus has been detected at Fort DeSoto. 

Dogs showing any symptoms of distemper should see a vet right away. 

"It is a virus that can attack your gastrointestinal systems, explained Gibsonton-based veterinarian Dr. Jenese Williams. "So vomiting, diarrhea, if we notice any of that going on, which is very common, but specifically if your pet is not vaccinated... and we're starting to see symptoms and changes like that, we want to be on high alert."

Williams said the virus also attacks the respiratory system. Symptoms may include coughing, nasal discharge and ocular discharge. Distemper can also affect the nervous system.

"So very severe cases you can get neurologic symptoms such as ataxia, which, basically if you see a pet walking like it's drunk and wobbly, (those) are signs of neurologic dysfunction.
