In Wisconsin an occupational disease in workers compensation claims is a disease or condition that is caused by the job duties or working conditions. This means that the condition must have developed due to work in the workplace and that the correlation between the work and the condition or disease is well known in medical research. An occupational disease is typically identified when it is shown that it is more prevalent in a given body of workers than in the general population, or in other worker populations. There is epidemiological evidence supporting neck and low back conditions developing over time from job duties at work.
