Modern clinical course of sexually transmitted infections (STIs) is characterized by a predominance of latent forms, which play an important role in the transmission of pathogens with the subsequent development of inflammatory diseases in the pelvic organs and severe complications in young adults. Methods. The objects for the study are health status, life-style characteristics and medical care assurance of 485 sexually transmitted infection patients aged 18-29 (control - 415 healthy persons of the respective age) living in the Republic of Sakha (Yakutia). Results. The incidence of sexually transmitted infection patients of the younger age has been influenced by adverse socio-hygienic factors. The main percentage of STI was taken by trichomoniasis (40.1 %), almost one in four cases was gonorrhea (up to 24.1 %), the third place belonged to syphilis (up to 18.5 %), the fourth - to chlamydia (up to 10.9 % ). Much less frequently diagnosed - the anogenital warts (4.1 %) and urogenital herpes (2.3 %). Ceftriaxone has become the drug of choice in the basic treatment of sexually transmitted infections. Conclusions. Medico-social rehabilitation of sexually transmitted infection patients should be based on complex of medical, social and psychological steps. At the heart of patients’ social rehabilitation is introduction of healthy lifestyle elements, which is currently the most relevant and effective in a number of crucial preventive measures that should be actively used for the sexually transmitted infection patients for correcting, improving and restoring their health.
