|Condition or disease|
This multi-center observational study examines risk factors for HCV transmission from mother to baby. The study will also assess risk factors associated with Hepatitis C Virus (HCV) infection in pregnant women. Also, the study will describe the outcomes of pregnant women with HCV as well as the outcomes of their infants to 18 months of age.
Approximately 750 HCV antibody positive pregnant women and their infants will be followed from baseline until the infant is 18 months. A randomly selected control cohort of 500 pregnant women who are HCV antibody negative will be followed until delivery.

- HCV infection of the offspring [ Time Frame: at 2 months and/or 18 months of age ]
The primary outcome is HCV infection of the offspring, where infection is defined by satisfying any one of the following criteria:
- HCV RNA positive (i.e. presence of viral load) by polymerase chain reaction (PCR) test at 2-6 months (2 month visit)
- HCV RNA positive and HCV antibody positive at the 18-24 months (18 month visit)
- HCV RNA positive at 18-24 months with a negative HCV antibody at 18-24 months and negative RNA at 2-6 months. However, the positive result must be confirmed by a repeat test on the 18-month sample to qualify.
- HCV antibody positive at 18-24 months with negative HCV RNA at both visits. However, the positive result must be confirmed by a repeat test on the 18-month sample to qualify.
- Clinical result that is either HCV RNA positive or HCV antibody positive obtained at 18 months or older with a confirmed clinical diagnosis of HCV, if a central laboratory sample could not be obtained at 18-24 months.
- Gestational age at delivery [ Time Frame: at birth ]
- Preterm delivery < 37 weeks of gestation [ Time Frame: at birth ]
- Gestational diabetes mellitus (GDM) [ Time Frame: during pregnancy ]
- Vaginal bleeding during pregnancy [ Time Frame: during pregnancy ]
- Preeclampsia [ Time Frame: during pregnancy ]
- Cholestasis [ Time Frame: during pregnancy ]
- Viral load in infant [ Time Frame: at birth, 2 months, and 18 months ]
- HCV antibody status in infant [ Time Frame: at 18 months of age ]positive or negative
- Birth weight of infant [ Time Frame: at birth ]
- Hyperbilirubinemia [ Time Frame: at birth ]Peak total bilirubin of at least 15 mg% or the use of phototherapy
- Neonatal intensive care unit (NICU) admission [ Time Frame: at birth ]
- Small for gestational age [ Time Frame: at birth ]Defined as less than the 5th percentile birth weight for gestational age at birth, assessed specifically by sex and race of the infant based on United States birth certificate data
- Neonatal infections [ Time Frame: at birth ]sepsis and pneumonia
