The aim of the study was to describe the diagnosis of HIV infection in a socially orderly person due to clinical evidence. A young socially successful man, on the basis of clinical considerations, underwent respective examination, which allowed diagnosis of HIV infection. The disease was not manifested by typical signs of clinical stage I, but by primary Herpes zoster and recurrent paratonsillar abscess. The wife of the patient was healthy. The hypothetical transmission of the infection was not established. The possibility of HIV infection in socially orderly individuals has been confirmed taking into account relevant clinical indications, first and foremost the episode of Herpes zoster in a young person with no obvious causes of immunodeficiency. Despite the guidelines for a revised clinical classification of HIV infection in adults and adolescents (WHO, 2006), persistent generalized lymphadenopathy is unessential in the clinical stage I and Herpes zoster may be manifested earlier the clinical stage II.
