π‘π¨ We understand many of you are concerned about the potential leptospirosis cases in our neighboring community, and while we have not seen any positive cases at this hospital, weβre here to provide clear, actionable information to protect your beloved pets. Leptospirosis is a serious bacterial disease, but with the right knowledge and preventative steps, we can keep our furry friends safe.
πΎ What is Leptospirosis? Leptospirosis is caused by bacteria called Leptospira. These bacteria thrive in warm, wet environments and are often spread through the urine of infected animals (like rodents, raccoons, and opossums) into standing water, puddles, wet soil, and even contaminated food. Pets can become infected by coming into contact with these contaminated sources through their skin, nose, mouth, or by drinking contaminated water.
πΎ How Does it Affect Pets? Leptospirosis can cause a wide range of symptoms, from mild to severe, and can be life-threatening. The bacteria primarily affect the kidneys and liver, leading to:
Fever
Lethargy and depression
Loss of appetite
Vomiting and diarrhea
Increased thirst and urination (early stages) or decreased/absent urination (later stages due to kidney failure)
Jaundice (yellowing of the skin, eyes, or gums)
Muscle pain, stiffness, or reluctance to move
Dehydration
Some pets may show no symptoms at all but can still carry and shed the bacteria. If you notice any of these signs, contact us immediately.
πΎ Can Humans Get Leptospirosis? (Yes, It's Zoonotic!) One of the reasons for heightened concern is that leptospirosis is a zoonotic disease, meaning it can be transmitted from animals to humans. While it's relatively rare to get it directly from your dog, humans can become infected through contact with contaminated water, soil, or the urine of infected animals. Always practice good hygiene: wear gloves when cleaning up pet urine, wash hands thoroughly, and avoid direct contact with suspect contaminated areas. It is important to note this is the most widespread zoonotic disease worldwide.
πΎ Prevention is Key! The good news is that leptospirosis is largely preventable:
Vaccinate
Avoid Standing Water
Rodent Control
Be aware of hygiene actions you can take
** It's important to understand that while the leptospirosis vaccine is highly effective and strongly recommended, it doesn't offer 100% guaranteed protection. Modern leptospirosis vaccines (specifically the 4-serovar vaccines, which are the most widely recommended) are very effective, with studies suggesting efficacy rates between 84% and 97% against clinical disease. This means they significantly reduce your dog's risk of becoming ill.
πΎ Can I test for lepto? YES! There is a test that includes a urine & blood sample and is sent to an outside lab. If you think your pet needs to be tested, they do need an appointment with their veterinarian to discuss clinical signs and possibly get more tests ran depending on what is going on to check their kidney and liver values.
π Please be patient with our staff as we have had a large increase in calls, emails, and text messages. We hope this post can answer some of your questions, and we are doing our best to get back to everyone in a timely manner. We will post more resources in the comments that you can follow.
