At this point, it is essential to specify that both health and occupational medicine do not have their own scientific status, because neither of them has built a body of knowledge with their own laws and theories, but rather has used sciences such as biology, chemistry, mathematics, and social sciences for their knowledge.

Another characteristic of both is their multidisciplinary nature, since both involve disciplines such as toxicology, safety and hygiene), ergonomics, statistics, administration, psychology, legislation, sociology, audiology, industrial engineering, among others.

However, the factors that differentiate it can be classified into two: its object of study and the second is the characteristic practice of each of them.

For occupational medicine, the object of study is the disease and the sick patient") as well as the causes that cause the disease, since they underlie the reason for the disease, since occupational medicine, being a branch of public health, cannot leave aside the reasons for the disease.

On the other hand, for occupational health, the object of study is the health of workers, considered as a collective phenomenon, and the space of the actions deployed is at the population level, it is preventive in nature and carried out by occupational doctors, with a duration of two years of study, a title to be obtained as "occupational health specialist."

Therefore, the concept of work (for this type of medical practice, which is the topic at hand) is located depending on the object of study, and refers to the work environment as the production area, where only risk factors or agents can be the determining causes of the individual health problems of each worker, where the majority of these are caused by unsafe acts.

At the same time, we see that the field of action of health at work is limited to researchers, professionals and technicians interested in improving working conditions; in demanding total quality in workplaces to achieve greater worker productivity.
