title: [Evolution of the new number of diagnoses of HIV infection in Asturias, Navarra and La Rioja].
abstract: BACKGROUND
  To describe the time-trend of people diagnosed with HIV infection in Asturias, Navarra and La Rioja up to 1998.
  
  
  METHODS
  HIV case reports since the beginning of the epidemic have been analysed. Only the first positive confirmed result for each patient was taken into account.
  
  
  RESULTS
  In the three regions a total of 7,870 HIV infections had been diagnosed by 1998 (4 cases per 1,000 inhabitants). New diagnoses decreased 60% since 1991 to 1998, with the greatest fall among intravenous drug users, and the lowest fall in sexually transmitted infections.
  
  
  CONCLUSIONS
  This time-trend supports a reduction in HIV transmission in these three regions; however, the number of new diagnosed infections remains high.
