Definition

IIntntraurautterineerine infections (IUI) are an established infections (IUI) are an established fact of the virus or microorganism entry to the fact of the virus or microorganism entry to the

fetus from mother, it has clinical and laboratory fetus from mother, it has clinical and laboratory signs of infection disease.signs of infection disease.

Among the IUI the most frequent is Among the IUI the most frequent is TORCHTORCH--infectioninfection, , that means Tthat means T--ToxoplasmosisToxoplasmosis, ,

RR--RubeolaRubeola, , CC––CytomegaliaCytomegalia, , HH––Herpetica Herpetica infectioinfectio, , OO––OtherOther. .

Intrauterine contamination is a possible fact of Intrauterine contamination is a possible fact of the entry to the fetus of various causative agents, the entry to the fetus of various causative agents,

but there is no clinical manifestationsbut there is no clinical manifestations..
