An outbreak of leptospirosis, a contagious bacterial disease, has been reported in dogs in the region, the San Diego County Health and Human Services Agency announced Thursday.
As of October, 34 confirmed and probable cases of leptospirosis have been documented in local dogs, mainly in the Hillcrest and Mission Hills areas. Several dogs had to be hospitalized and at least one was euthanized.
Boarding at kennels that allow dog-dog interaction is a major risk factor, although some sick dogs only interacted with other dogs in dog parks. The kennels associated with the cases notified the owners of all possible contacts from diagnosed cases and closed for at least two weeks for cleaning and disinfection.
Signs of leptospirosis in dogs are varied and can include fever, muscle weakness, vomiting, diarrhea, loss of appetite, low energy, and frequent urination which can be bloody.
No human cases have been associated with this outbreak in dogs, but anyone who develops a fever, headache, muscle pain – especially in the back and calves – or any other illness after contact with a sick dog should consult their healthcare provider.
This week, the county sent a health advisory on the outbreak to local doctors and veterinarians.
Leptospirosis is a disease caused by different types of spirochete bacteria called leptospira. These bacteria can infect multiple types of mammals, including humans, dogs, rats, mice, raccoons, skunks, and opossums. The bacteria are excreted in the urine of infected animals and can contaminate food, water, soil or bedding. Dogs and humans can become infected by direct contact with abrasions, mucous membranes or by drinking contaminated water.
“When dogs visit kennels and parks and play, lick and sniff each other, they run the risk of getting these bacteria,” said Dr. Wilma Wooten, the county public health officer. “If your dog shows any signs, take him to your vet immediately.”
A vaccine is available to prevent leptospirosis in dogs, especially for those who board kennels and visit dog parks.
