Occupational health surveillance. We're making progress, but is it enough?

1. Surveillance data are used in the development of health strategies and policies. 2. The Sensor program bridges the gap that exists between the reporting of occupational disorders and infectious disease. 3. A shortage of health care professionals experienced in health surveillance has been a hindrance to the occupational health profession over the years. However, this is changing as more individuals seek advanced degrees. 4. As the ability to collect and analyze data improves, the health and safety of employees also should improve.
