Neonatal hepatitis is a rare but serious liver disease in infants during the first year of life. The term "neonatal hepatitis" refers to infectious liver damage that develops either in utero or during the first three months after birth. The timing of disease onset varies significantly depending on the etiology and is determined by the gestational period during which the fetus was infected as well as the incubation period. Therefore, in some cases, symptoms may appear almost immediately after birth, and in others - weeks or even months later.
