Health of the population - a statistical concept that is characterized by a complex socio-economic and demographic indices, level of physical development, morbidity and disability specific groups of people.

Illness - total or partial restriction of vital activity, due to the disruption of the compensatory - adaptive mechanisms under the influence of external and internal factors and is characterized by restraint of (free hand) freedom.
Disease - the fact of the disease in an individual. The concept of disease concerns a specific person, in contrast to the concept of the disease, which is used to refer to abstract a nosological unity.
