title: Measuring the HIV epidemic: the Western Australian experience.
abstract: Previous discussion about sources of error in measuring the human immunodeficiency virus (HIV) epidemic has tended to emphasise errors which underestimated the number of HIV infected persons. Data are provided from Western Australia illustrating potential errors which may result in overestimating the size of the epidemic. Duplication of persons notified in more than one State and multiple notifications by doctors and laboratories of single cases may give rise to substantial errors in over-estimation.
