Cytomegalovirus is the most common viral infection in the fetus, and spontaneous abortion may result from maternal CMV infection in the first trimester. Herpes simplex infection leads to manifestations such as bullae, microcephaly, hydrencepahly, and encephalitis. Without medical intervention, vertical (maternal-to-child) transmission of HIV is about 25. Varicella zoster virus carries no known risk to the fetus after 20 weeks' gestation.

An autosome is a non-sex chromosome common to both males and females. The X chromosome is the larger female chromosome, whereas the Y chromosome is the smaller male chromosome. Homozygous gene pairs have identical genes, whereas heterozygous gene pairs have differing genes. A genotype is the genetic makeup of an individual. The genome is the complete set of genes present in each person. The phenotype is the observable genetic differences expressing a person's genotype, such as hair and eye color.
