Since the placenta cannot filter out extremely small disease carriers, such as viruses, children can be born with malaria, measles, chicken pox, mumps, syphilis, or other venereal diseases that have been transmitted from the mother.

Rubella is the most widespread of the viruses that have a teratogenic effect. If a pregnant woman contracts rubella in the first three months of pregnancy, she is likely to give birth to a child with a congenital abnormality such as heart disease, cataracts, deafness, or mental retardation.

The vast majority of children with AIDS contracted the disease sometime between early pregnancy. The disease is usually transmitted from the mother through the uterus during pregnancy or is acquired by the off-spring at birth.

Toxemia is a frightening condition that is potentially fatal for the mother and the fetus. It is characterized by high blood pressure, swelling, and weight gain due to a build-up of fluid in the body tissues, and the presence of protein in the mother's urine.

Women with toxemia frequently give birth to premature babies or to babies smaller than average for their gestational age.
