The presented article is devoted to the study of the relationship of adolescents with tubercular infection to their parents. Tuberculosis is known to be a serious somatic infectious disease. Its treatment is carried out in a hospital and outpatiently for a long time. The prognosis of the course and cure of the disease is not always clear and predictable. The severity of the disease, side effects of drugs, changes in conditions and quality of life, disruption of social contacts, uncertainty of near and distant health prognoses, disruption of family relationships, social and material distress significantly affect attitudes toward the disease, treatment and cure for tuberculosis. Adolescence is one of the most difficult periods in every person’s life. The disease has a significant effect on the adolescent’s growing up, their ideas of future. Parental support is especially important for young people who have to be treated for a long time, who are aware of the severity of their disease, its social danger. Relations with parents play an important role in adapting to the disease, in forming adherence to treatment. However, often parents themselves become a source of infection for their child, the formation of multiple drug resistance. Improper upbringing, inadequate attitude to the child’s disease and its treatment lead to disruption of the medical-diagnostic and medical-rehabilitation processes aimed at treating tuberculosis.
