title: Geographic and temporal stability of HIV seroprevalence among pregnant women in Bujumbura, Burundi.
abstract: OBJECTIVE
  To establish whether HIV seroprevalence in Bujumbura is stable or continuing to increase.
  
  
  METHODS
  HIV seroprevalence data among pregnant women from 1986 were compared with comparable data from 1991-1992.
  
  
  RESULTS
  HIV seroprevalence among antenatal clinic attendees at three sites was 10.5, 28.0 and 11.9% in 1986, compared with 7.7, 25.6 and 12.4%, respectively, in 1991-1992. A weighted least squares analysis showed significant differences in HIV seroprevalence between the different sites (chi 2, 71.71; P > 0.0001), but no evidence of any differences between the 1986 and the 1991-1992 prevalence levels (chi 2, 0.51; P = 0.6).
  
  
  CONCLUSIONS
  Bujumbura appears to be in the endemic phase of the spread of HIV. The stable geographic variation among clinic populations in Bujumbura suggests the need for focused interventions, and a general need for surveillance data to be gathered from numerous sites so to identify those with the highest incidence of HIV infection.
