title: New Zealand's HIV infected population under active follow-up during 2000.
abstract: OBJECTIVE
  To audit New Zealand's HIV infected population currently under active follow-up.
  
  
  METHODS
  Multiple sources were used to determine anonymously the demographic and management characteristics of HIV infected individuals being monitored with HIV viral load measurements and/or receiving antiretroviral therapy during 2000.
  
  
  RESULTS
  593 people (480 males and 113 females) were under active follow-up. The most common transmission risk was male homosexual contact (56%) followed by heterosexual contact (28%), injecting drug use (3%) and mother to infant transmission (1%). Ethnicity data showed a disproportionate number of Africans (13%) compared to recent census figures. Anti-retroviral therapy was used in 71% of the cohort of whom 62% had HIV viral load measurements below 400 copies/mL. An upper estimate of diagnosed HIV individuals living in New Zealand at 30/9/2000 was 801.
  
  
  CONCLUSIONS
  This is the first time that the demographic and clinical state of HIV infected individuals has been assessed throughout New Zealand. The results suggest a slightly lower number of HIV infected individuals currently living in New Zealand than previously estimated. Anti-retroviral therapy is being used effectively within the HIV infected population. The changing demographics, with a higher proportion of people under care from Africa, increasing numbers of females, and an increase in the proportion with heterosexual risk factors are particular challenges.
