Objectives:To analyze mother-to-child HIV transmission (MTCT) rates over time in light of changes in management, demographic, and pregnancy characteristics.Design:Population-based surveillance data on diagnosed HIV-positive women and their infants are routinely collected in the UK and Ireland.Methods:A total of 12 486 singleton pregnancies delivered in 2000-2011 were analyzed. HIV infection status was available for 11 515 infants (92.2%).Results:The rate of MTCT declined from 2.1% (17/816) in 2000-2001 to 0.46% (nine of 1975, 95% confidence interval: 0.21-0.86%) in 2010-2011 (trend, P = 0.01), because of a combination of factors including earlier initiation of antenatal combination antiretroviral therapy (cART). Excluding 63 infants who were breastfed or acquired HIV postnatally, MTCT risk was significantly higher for all modes of delivery in women with viral load of 50-399 copies/ml (1.0%, 14/1349), compared with viral load of less than 50 copies/ml (0.09%, six of 6347, P
