title: [Trend of HIV seroprevalence among mothers of new-born infants from 1996 to 1999].
abstract: BACKGROUND
  To analyze the evolution of HIV prevalence in mothers of Spanish new-borns.
  
  
  METHODS
  Unlinked anonymous testing of HIV in blood spots for detection of metabolic diseases of all new-borns in 1996-1999 in seven regions: Baleares, Canarias, Castilla-La Mancha, Castilla y León, Galicia, Melilla and Murcia. HIV antibody detection was done with ELISA and confirmation with a immunoblot.
  
  
  RESULTS
  The prevalence of HIV antibodies was 0.99 per 1,000 in 1996, 1.29 in 1997, 1.42 in 1998 and 1.54 in 1999. There was an upward trend both in the global sample (p = 0.0015) and in those from Canarias (p < 0.0001) and Castilla y León (p = 0.0389). The prevalence of HIV-1 for the whole period was 1.31 per 1.000 and of 1.13 per 100.000 for HIV-2.
  
  
  CONCLUSIONS
  There is a need to offer systematic counselling and HIV testing to all pregnant women.
