Hepatitis C virus (HCV) infection is a global problem in our health systems. The prevalence of infected patients in general population is about 2%. In the subgroup of pregnant woman the percentage of infected patients ranges from 1-3%. Several studies have described the relationship between pregnancy and chronic HCV infection, and in most cases serum transaminases levels return to normal values while HCV-RNA levels increase during the second and third trimester. The influence of maternal hormones after delivery in the natural history of HCV infection has not been sufficiently studied and consequently remains controversial. This case report shows the peculiar clinical course of a patient with chronic HCV infection in the puerperium.
