Always contact your veterinarian and your physician if you have concerns about a possible exposure to an infected animal. Do not handle or come in contact with urine, blood, or tissues from your infected pet before it has received proper treatment. As a general rule, always wash your hands after handling your pet or anything that might have your pet's excrement on it. If you are cleaning surfaces that may be contaminated or have urine from an infected pet on them, use an antibacterial cleaning solution or a solution of 1 part household bleach in 10 parts water. Make sure that your infected pet takes all of its medicine and follow up with your veterinarian.
Rodents can carry and spread the bacteria.
Get your pet vaccinated against leptospirosis. It is important to get your pet vaccinated again even if it gets leptospirosis because it can still get infected with a different strain of leptospires.
