A recent study (S Lopata et al. Pediatrics 2020; 145: e20192482. Link to Abstract/Video: Hepatitis C Testing Among Perinatally Exposed Infants) was well-summarized in a recent practical gastroenterology issue: Full link: Hepatitis C Screening of Infants

An excerpt:

• During the study period, 384,837 mother-infant dyads were enrolled in the Tennessee Medicaid program, and 4072 of these mothers had HCV during pregnancy…
• The prevalence of infants with exposure to HCV increased significantly throughout the study with 5.1 infants exposed to HCV per 1000 live births in 2005 and 22.7 infants exposed to HCV per 1000 live births in 2015 with 92.9% of the mothers of these children being white.
• Only 946 infants (23%) exposed to HCV had HCV testing in the first 2 years of life, and 354 of these infants (41%) had testing per recommended national guidelines…
• Infants who were exposed to HCV and who were African American or who lived in rural areas next to metropolitan areas were significantly less likely to have HCV testing.

My take: As with adults, this study shows that selective HCV testing is a messy proposition.  This study shows that more than 75% of at risk infants are not being tested for HCV.  Now that curative treatment is available, more needs to be done to address this public health failure.
