    Leptospirosis (Weil’s Disease)

    Leptospirosis can lead to severe symptoms, including fever, headaches, muscle pain, jaundice, and in serious cases, liver or kidney failure.

    Although rare, the disease can cause serious illness if not recognised early and prevented through good hygiene and safe working practices.

    • Why It Matters

      It most commonly affects employees working outdoors, in drainage, flood recovery, construction, agriculture, pest control and waste management.

      The infection is spread when bacteria enter the body through cuts, abrasions, or contact with the eyes, nose, or mouth.

      Early recognition, good hygiene, and correct use of personal protective equipment (PPE) can prevent infection and protect workers’ health.

    • Common causes & risks

      • Working near rivers, ponds, sewers, or flood water.
      • Contact with rodents or areas contaminated with animal urine.
      • Inadequate handwashing or welfare facilities.
      • Failure to wear appropriate PPE.
      • Uncovered cuts or abrasions during outdoor or wet work.

    • Symptoms to watch for

      • Flu-like symptoms: fever, chills, severe headache, muscle pain, and fatigue.
      • Nausea, vomiting, or diarrhoea.
      • Yellowing of the eyes or skin (jaundice).
      • Pain in the lower back, abdomen, or calves.
      • In severe cases: liver and kidney damage, or meningitis.

      If you experience any of these symptoms after working in or around water or rodent-infested areas, seek medical attention immediately and inform your manager.

    10 Controls to follow

    • 1. Wear appropriate PPE – use waterproof gloves, boots, and coveralls when working in or near water, drains, or contaminated areas.

    • 2. Wash thoroughly after work – always wash hands and exposed skin before eating, drinking, or smoking / vaping.

    • 3. Cover all cuts and grazes – use waterproof dressings before starting work and change them regularly.

    • 4. Avoid contact with stagnant or flood water where possible. Report contaminated areas to your supervisor.

    • 5. Do not touch your mouth, eyes, or nose with unwashed hands.

    • 6. Use on-site welfare and washing facilities – never eat / drink in contaminated work areas.

    • 7. Report rodent activity immediately so pest-control measures can be arranged.

    • 8. Store and clean PPE properly – do not take contaminated clothing or footwear home.

    • 9. Attend training and briefings – ensure you understand the risks and the hygiene standards required for your role.

    • 10. Report any illness early – if you feel unwell within 21 days of possible exposure, inform your manager and tell your GP you may have been exposed to Leptospirosis.

    Good Practice and Legal Responsibilities

    Employees must

    • Follow all hygiene and PPE procedures.
    • Report hazards, including standing water and rodent evidence.
    • Use facilities provided and maintain personal cleanliness.
    • Inform your supervisor if you suspect exposure or feel unwell. Consult your GP.

    • Employers must

      • Assess the risk of Leptospirosis exposure and provide suitable welfare facilities.
      • Supply and maintain appropriate PPE.
      • Provide training and supervision to ensure safe working practices.

    • Discussion Points

      • Where in our work might contact with contaminated water or rodents occur?
      • Are welfare and washing facilities adequate on site?
      • How can we ensure all cuts and abrasions are covered before work begins?
