An outbreak of leptospirosis, a contagious bacterial disease in dogs in the region, was reported Thursday, the San Diego County Agency for Human Services and Health said.
Since October, 34 confirmed and probable cases of leptospirosis have been documented among local dogs, mostly in the Hillcrest and Mission Hills areas. Several dogs required hospitalization and at least one was euthanized.
Boarding kennels that allow interaction between dogs is a major risk factor, although some sick dogs only had contact with other dogs at dog parks. Case-linked kennels notified owners of all possible contacts of 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 linked to this outbreak in dogs, but anyone with fever, headache, muscle aches (especially in the back and calves) or any other illness after contact with a sick dog should consult your doctor.
This week, the county sent health advice to local doctors and veterinarians about the outbreak.
Leptospirosis is a disease caused by several species of spirochete bacteria called leptospira. These bacteria can infect several species of mammals, including humans, dogs, rats, mice, raccoons, skunks, and opossums. Bacteria are shed in the urine of infected animals and can contaminate food, water, soil or beds. Dogs and people can become infected through direct contact with skin abrasions, mucous membranes, or drinking contaminated water.
“When dogs visit kennels and parks and play, lick and smell each other, they run the risk of suffering from these bacteria,” said Dr. Wilma Wooten, the county’s public health official. “If your dog shows any signs, you should take him to your vet immediately.”
A vaccine is available to prevent leptospirosis in dogs, especially for those who board kennels and frequent dog parks.
