SO Annu Conf Australas Soc HIV Med. 1993 Oct 28-30;5:39 (abstract no. TE4). Unique Identifier : AIDSLINE ASHM5/94348969 AB OBJECTIVE: To describe the epidemiology of perinatal HIV exposure and transmission in Australia. METHODS: A registry of all cases of perinatal exposure to HIV was established using data retrieved retrospectively to test for possible factors affecting transmission rate, maternal and infant variables were examined using Chi square. RESULTS: Between 1982 and June 1993, 72 babies were reported as perinatally exposed to HIV infection. Six infants have indeterminate status. Of the 66 children for whom infection status could be determined, 22 (33%) have acquired HIV infection. Infants horn to mothers infected as the result of injecting drug use had a 47% transmission rate. Those infants born to mothers from Pattern II countries had a transmission rate of 83% (p = 0.02). Among 19 infants known to have been breastfed, 10 are infected (52%). Among 29 infants who were never breastfed, 7 are infected (24%) (p = 0.04). No other factors were noted. CONCLUSION: The perinatal HIV register appears informative and prospective data acquisition is advocated.
