Estimated rates of perinatal human immunodeficiency virus (HIV) transmission for different times of gestation and delivery in nonbreast feeding populations

Estimated rates of perinatal human immunodeficiency virus (HIV) transmission for different times of gestation and delivery in nonbreast feeding populations. Estimates are based on a hypothetical cohort of 100 children born to HIV-infected women without any interventions. Numbers in blue indicated number of children at risk for infection.
