Leptospirosis: Diagnosis & Treatment of This Waterborne Infection
A clear guide to leptospirosis, a bacterial infection linked to contaminated water and flooding, requiring prompt antibiotic treatment.
Treatment usually begins with
Blood Testing
Clinical Assessment
Antibiotic Therapy
Organ Function Monitoring
Treatment with the appropriate antibiotic is most effective when started early, alongside monitoring for kidney and liver involvement.
You may need this evaluated if...
Leptospirosis is considered when these appear, especially after exposure to floodwater or contaminated water:
- Sudden high fever with severe muscle pain, especially in the calves
- Yellowing of the skin or eyes
- Reduced urine output
- Recent exposure to floodwater, ponds or contaminated water
Most cases of leptospirosis respond well to prompt antibiotic treatment, especially when started before complications develop.
What is Leptospirosis?
Leptospirosis is a bacterial infection spread through contact with water or soil contaminated by animal urine, often linked to flooding, causing fever and, in some cases, kidney or liver complications if untreated.
Linked to Flooding & Contaminated Water
Cases often rise after heavy rain or flooding when contaminated water is more widespread.
Wide Range of Severity
Illness can range from mild flu-like symptoms to severe organ involvement.
Early Treatment Prevents Complications
Starting antibiotics early significantly reduces the risk of kidney or liver complications.
Distinctive Symptom Pattern
Severe calf muscle pain alongside fever is a characteristic clue.
Common Symptoms
- Sudden high fever with chills
- Severe muscle pain, especially in the calves
- Headache
- Red eyes (conjunctival redness)
- Jaundice in more severe cases
What Increases Your Risk
A combination of exposure, immune status and underlying health conditions can increase the likelihood of this infection.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
Leptospira Serology or PCR Testing
Confirms the specific infection.
Kidney & Liver Function Tests
Assesses for organ involvement guiding treatment intensity.
Complete Blood Count
Checks for anemia or low platelet count associated with the infection.
Urine Testing
Evaluates kidney involvement and monitors recovery.
Treatment Approaches
Medical Management
- A course of antibiotics effective against leptospirosis, started as early as possible
- Supportive care for fever and muscle pain
- Close monitoring of kidney and liver function
- Dialysis support in the rare case of significant kidney involvement
Hospital-Based & Advanced Care
Leptospirosis is treated with medication and supportive care. Hospital admission is used for monitoring and organ support in more severe cases.
Treatment decisions are guided by culture results, severity and your overall health, not a single standard prescription.
Know When to Act
Recognising these signs early and acting promptly helps prevent serious complications.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing concern.
- Fever with muscle pain after possible floodwater exposure
Seek Urgent Care
Reach out for emergency care immediately if you notice any of the following.
- Yellowing of the skin or eyes, or a marked drop in urine output
