OBJECTIVES: To estimate the HIV seroprevalence rate in a representative sample of all women bearing live children in Ontario, Canada. METHODS: Neonatal heelprick specimens routinely collected for genetic screening were tested for HIV from Nov. 1/89 to Oct. 31/91. A customized computer program randomly selected 60% of all specimens for testing. Month and year of delivery, and hospital of birth were the only demographic information linked to the specimen test result. The computer program only provided rates by provincial health units if at least 200 observations were in the denominator. Specimens were first tested with a commercial EIA assay (Organon Teknika) and confirmatory testing was conducted using a mini-blot system (Genetic Systems). RESULTS: During the first year of testing (Nov. 1/89-Oct. 31/90) 94,119 specimens were tested and 26 confirmed as seropositive for the crude overall seroprevalence rate of 2.8 per 10,000 women having live births (95% CI 1.8-4.1). In the second year (Nov. 1/90-Oct. 31/91) 90,255 specimens were tested and 20 were confirmed as positive for a crude seroprevalence rate of 2.2 per 10,000 (95% CI 1.3-3.4). In both years, the majority of positives came from babies born in three main areas of the province. CONCLUSIONS: HIV infection among childbearing women in Ontario, Canada has remained relatively stable over the two years of testing under an anonymous, unlinked study.
