Public health is a theoretical and practical activity undertaken in order to prevent diseases, prolong life and improve its quality population-wide. In the past these tasks used to be carried out by doctors, however their activities were scattered and not contained in organization structures. In the beginning of the 20^th century the period of structuring and consolidating of the public health started, it was also the time when a new occupation was created – public health specialist. In time, a clear distinction between medicine (so-called curative medicine) and public health was made. However, already in the 1970s, as a result of numerous circumstances, it was decided that the scopes of both of the areas were becoming closer and that it was necessary to cooperate and communicate. As a result the areas and occupations were tried to be integrated.
