  • For some people, hepatitis B is mild and lasts only a few weeks (known as an "acute" infection), but for others, it can become a chronic disease, leading to liver scarring, liver failure, and cancer that can even be life-threatening. (uberant.com)

  • 13] There is practically no maternal-fetal transmission of HAV, as anti-HAV immunoglobulin (Ig) G antibodies present during the initial stages of HAV infection cross the placenta and provide protection to the infant after delivery,[3] and it poses a minimal risk to the fetus and newborn.
