title: [Clinical and epidemiological characteristics of persons newly diagnosed of HIV infection].
abstract: BACKGROUND
  We describe the characteristics of people with a recent diagnosis of HIV infection.
  
  
  METHODS
  Series of 126 new cases of HIV infection diagnosed in an infectious diseases Service.
  
  
  RESULTS
  Sexual transmission was the commonest form of infection (74%). Fifteen percent of individuals were aged over 50 years and 16% were immigrants. A late diagnosis (stage C) accounted for 36% of cases and it was associated with being more than 50 years old (OR: 5.1; 95% CI: 1.6-16.8).
  
  
  CONCLUSIONS
  It is necessary to implement HIV infection surveillance systems and to improve preventive services.
