Leptospirosis is a bacterial infection spread through the urine of infected rats and other animals. Construction workers are at risk when working near watercourses, sewers, canals, or in damp environments where rats are present. The severe form, known as Weils disease, can cause organ failure and death if untreated. This talk explains how the infection spreads, the symptoms to recognise, and the precautions that prevent it.
Key Hazards
Severe organ failure and potential death from untreated Weils disease
Infection through open cuts or wounds exposed to contaminated water
Bacteria entering through mucous membranes of eyes, nose, or mouth
Delayed diagnosis because early symptoms resemble common flu
Control Measures
Cover all cuts, grazes, and wounds with waterproof dressings before starting work.
Wash hands thoroughly with soap and water before eating, drinking, or smoking.
Wear waterproof gloves and overalls when working in or near potentially contaminated water.
Avoid touching your face, eyes, or mouth while working in areas where rats may be present.
Report any rat sightings or evidence of rat activity to the site manager for pest control action.
Seek medical attention immediately if you develop flu-like symptoms after working near water.
Tell your doctor that you work on construction sites near water and may have been exposed.
Clean and disinfect any equipment that has been in contact with canal, river, or sewer water.
Carry a leptospirosis warning card in your wallet so medical staff are aware of the risk.
Remember
Cover all cuts and wounds with waterproof dressings before working near water or in damp areas
Wash hands thoroughly before eating, drinking, or smoking after any water exposure on site
Wear waterproof gloves and overalls when working near canals, rivers, sewers, or standing water
Seek medical attention immediately if flu-like symptoms develop after working near water
Tell your doctor you work on construction sites and may have been exposed to leptospirosis
Report rat sightings or evidence of rat activity to the site manager for prompt pest control
