Background Estimation of the risk of vertical transmission of human immunodeficiency virus (HIV) has been complicated by the lack of a reliable diagnostic test for paediatric HIV infection.
Methods A literature search was conducted to identify all statistical methods that have been used to estimate HIV vertical transmission risk.
Although the focus of this article is the analysis of birth cohort studies, ad hoc studies are also reviewed.
Conclusions The standard method for estimating HIV vertical transmission risk is biased and inefficient.
Various alternative analytical approaches have been proposed but all involve simplifying assumptions and some are difficult to implement.
However, early diagnosis/exclusion of infection is now possible because of improvements in polymerase chain reaction technology and complex estimation methods should no longer be required.
The best way to analyse studies conducted in breastfeeding populations is still unclear and deserves attention in view of the many intervention studies being planned or conducted in developing countries.
