> The infectious diseases in pregnancy

Not all the infectious diseases taken in pregnancy harm the baby: those that involve risk and that may have adverse effects on the child’s development in the course of pregnancy are rubella and toxoplamosi.

In the first 8-10 weeks of pregnancy if the mother gets sick of one of these diseases , the risk of damage to the fetus is very low: in fact, the placenta is the barrier for the passage of the virus or parasite responsible for the disease.

But in the few cases where this defence does not work, the damage to the child can be very serious.

In the following weeks (the foetal period) the transmission of the disease from mother to child è più frequent, but the damage that it causes are usually minor. However, in the cases più serious, can occur malformations true, defects of hearing and sight, motor disorders, or insufficient intellectual.

it Is therefore necessary for the mother to know whether there’s a risk of getting sick rubella and toxoplasmosis during pregnancy, and in the case that this risk exists in take precautions.

Even the HIV virus (responsible for AIDS), hepatitis, and the micro-organism of syphilis, if present in the mother, can pass to the fetus and cause problems. Also in this case, the blood test allows to detect the possible presence of this disease and to decide the behaviors, care and proper precautions.
