According to the current medical knowledge, the so-called “emergency diagnosis“ is attributed to the CFS. So far,it is not clearly decided whether it is a disease or nonspecific symptoms which may precede the manifestation of a specificdisease for a couple of years, namely autoimmune, tumorous, endocrine, metabolic or infectious one. CFS has not beenrecognized as a diagnosis by the WHO, consequently it was not included in the 10th International Classification of Diseases.Accordingly, it is still considered a syndrome, i. e. the sample of objective and subjective symptoms which we are not able toclassify precisely as a diagnosis and which may occur in relation to different diseases.The article includes the update review of current views on the CFS.
