What is Leptospirosis?

You may not have 'leptospirosis' on your trivia night shortlist of words to spell, but it's one of those conditions you should know about — especially if you're an outdoorsy type or a pet lover. What is leptospirosis? It’s a nasty bacterial infection that can affect both humans and animals. It is spread through contaminated water, soil, and even the “tracks” left by some of nature’s least-loved critters (mice and rats, we’re looking at you!).

While the name might be a mouthful, the good news is that leptospirosis is preventable — and we’re here to explain how. From leptospirosis symptoms to top tips for leptospirosis prevention, let’s roll up our sleeves and dig into what you need to know!

How is Leptospirosis Transmitted?

Leptospirosis bacteria is transmitted through contact with the urine or saliva of infected animals or anything contaminated with these fluids, like water, soil, or even food. The bacteria are sneaky travelers that enter your body through tiny cuts or scrapes. That’s why we urge you to wear gloves when scrubbing surfaces fouled by mice or rats.

You know that stench that comes with mice or rats? That’s their urine, and chances are you’re inhaling tiny particles of it. (Ewww!) That’s not just gross — it’s dangerous. Leptospirosis bacteria can get you through the membrane in your eyes, mouth, and nose. So, safety goggles, gloves, and a mask are a must whenever you’re dealing with rodents! Score one for leptospirosis prevention.

Common Carriers of Leptospirosis

Leptospirosis bacteria love to travel — and they’re not picky about their ride. Common leptospirosis carriers include:

  • Rodents: Mice and rats are the top offenders.
  • Mosquitoes, fleas, and ticks: Yet another reason to hate these pests! Learn more about the diseases mosquitoes can carry.
  • Cats, dogs, and other animals: From livestock to wildlife. 

Pest control and keeping an eye on pets are critical steps in leptospirosis prevention. 

How Leptospirosis Spreads to Humans and Animals

Leptospirosis bacteria are sneaky! Of course, you’re not going to (knowingly) splash about in rat urine! Who would? But do you dig in the garden or pull weeds without wearing gloves? Yeah, even a trace of urine in the soil left by an infected rat or raccoon is all it takes. After heavy rains or hurricanes, contaminated water can end up anywhere — in lakes, rivers, streams, and even in your own backyard. Does your dog lap up puddles after it rains? So do rodents and wildlife that may already be infected. Does your cat catch and eat rodents? Eating or chewing on the carcass of a contaminated critter is another way to contract leptospirosis.

Leptospirosis bacteria can enter the bloodstream through tiny cuts, scrapes, or mucous membranes. It’s sneaky, but simple precautions like gloves and boots can help your leptospirosis prevention efforts.

Leptospirosis Symptoms in Humans and Animals

Leptospirosis symptoms can be subtle at first. They don’t really scream “infection!” right away, but they can turn serious if ignored.

Early Symptoms of Leptospirosis

Leptospirosis symptoms play it cool at first, making you think it’s just a bad day or a common bug. In people, early signs include fever, chills, headaches, and muscle aches. Your furry friend might lose their appetite, seem lethargic, or start vomiting. These early signs are easy to brush off, but if there is any chance you or your pets have been exposed, it’s better to take them seriously.

If these early symptoms are missed or ignored, the infection can progress and lead to severe complications.

Severe Leptospirosis Symptoms and Complications

In humans, severe symptoms include high fever, intense muscle pain, diarrhea, nausea, vomiting, yellowed skin (jaundice), rash, and pounding headaches. Worse, untreated infections can lead to kidney or liver damage or even severe breathing problems. For our pets, the stakes are just as high, with risks of organ failure or respiratory distress. Early recognition and treatment are essential. 

Diagnosing and Treating Leptospirosis

Learning what leptospirosis is and recognizing its symptoms are just half the battle. What should you do if leptospirosis symptoms occur and you suspect an infection?

How Leptospirosis is Diagnosed

Think you or your pet may have leptospirosis? Diagnosis begins with discussing your symptoms with a doctor or vet while explaining the potential exposure to contaminated water or animals. Your healthcare practitioner can confirm the diagnosis with a simple blood or urine test. For pets, your vet may run extra tests to make sure their organs are functioning properly.

Treatment Options for Leptospirosis

Leptospirosis is undeniably scary, but the good news is that it’s treatable! Antibiotics are the first line of defense and work best when started early. Your doctor or vet may also recommend supportive care, like intravenous fluids or medications, to manage symptoms. In severe cases, hospitalization may be required to address complications like organ damage. 

With early diagnosis and treatment, a full recovery is not just possible — it’s likely.

Preventing Leptospirosis Infection

As is often the case, leptospirosis prevention beats treatment every time! It’s easier than you think and involves a few smart precautions.

Leptospirosis Prevention Pest Control 

The first step in leptospirosis prevention is tackling the source: wildlife, rodents, mosquitoes, and other pests. These critters are more than just nuisances — they can infect your property with bacteria dangerous to you, your family, and your pets.

  • Keep your property tidy: Secure trash bins with tight lids, avoid leaving pet food outdoors, clean up the grill after barbecuing, and clean up spilled birdseed from any feeders. All these attract rodents and wildlife.
  • Repair fences and seal entry points: Keep your fences in good repair to deter wildlife and seal even small holes or gaps in your home’s exterior to prevent rodents from moving into your home, garage, attic, or crawl space.'
  • Eliminate standing water and repair leaky irrigation: Mosquitoes, fleas, and ticks are attracted to standing water and moist areas. Their presence increases the risk of contamination on your property.
  • Maintain your yard: Trim grass and shrubs, remove weeds, and discard leaf litter where mosquitoes, ticks, fleas, and rodents may hide.
  • Call professional pest control: Mosquito Joe® is your trusted pest control specialist, providing:

Reducing Exposure to Contaminated Water and Soil

Occasionally, wily critters can sneak past even the best pest control, and many outdoor adventures take you onto the wildlife’s turf. Learning how to reduce exposure to contaminated water and soil is a must for leptospirosis prevention:

  • Avoid stepping into puddles, ponds, or streams: Especially after heavy rains or in areas where wildlife or rodents may roam.
  • Be cautious with water sports: Popular activities like kayaking, boating, or inner-tubing on lakes and rivers can pose a risk of exposure, especially following heavy rains. If you’ll be playing in wild water, take the following precautions:
    • Always wash thoroughly with soap and water after water activities.
    • Cover any cuts or wounds with waterproof bandages first.
    • Avoid swallowing water and keep pets away from suspect areas.
  • Bring your own water: Always carry clean, treated water (either boiled, filtered, or purified) for drinking or cooking for both you and your pets.
  • Treat natural water sources: If you must use water from lakes, rivers, or streams, boil or purify it before drinking, cooking, or bathing with it.
  • Practice good hygiene: Always wash your hands with soap and water after outdoor activities, particularly before eating.
  • Remain alert for potential symptoms: If you or your pets experience early leptospirosis symptoms after visiting a lake or river, contact medical assistance promptly.

Vaccination for Pets as a Preventive Measure

Think of vaccination as your pet’s first line of defense against contracting leptospirosis. If your dog loves exploring the great outdoors or your cat is a mighty hunter, the vaccine can help protect them from serious illness. It reduces the risk of infection and complications, so ask your vet whether a leptospirosis vaccine is right for your furry friends.
