What is health surveillance for?

The aims of health surveillance are to:

  • protect your health by detecting the early signs of illness or injury that may be due to exposure to hazards at work;
  • help an employer to check if measures used to control and prevent exposure are effective; and
  • help an employer assess the immunity of workers who are exposed to biological hazards such as hepatitis B or Leptospirosis (a bacterium found in rat urine in contaminated water - canal and sewer workers are most at risk).
