The study of viral hepatitis was expanded over the past decade with the emergence of new viruses, therapies, and vaccination guidelines as well as new data on the risks of perinatal transmission. There are now at least six hepatitis viruses. Hepatitis A and E are causes of epidemic, enteric infection and do not carry a significant risk of chronic infection. Hepatitis B, C, D, and G are hematogenously spread and are significant causes of chronic hepatitis, hepatocellular carcinoma, and cirrhosis. The following report reviews the types of hepatitis as well as the consequences of infection to the mother and fetus.
