Congenital toxoplasmosis is a specific form of toxoplasmosis in which an unborn fetus is infected via the placenta. [55] Congenital toxoplasmosis is associated with fetal death and miscarriage, and in infants, it is associated with hydrocephalus, cerebral calcifications and chorioretinitis, leading to encephalopathy and possibly blindness.

TORCH syndrome is a cluster of symptoms caused by congenital infection with toxoplasmosis, rubella, cytomegalovirus, herpes simplex, and other organisms including syphilis, parvovirus, and Varicella zoster. [1] Zika virus is considered the most recent member of TORCH infections. [2]
Congenital toxoplasmosis may lead to hydrocephalus, seizures, lymphadenopathy, hepatosplenomegaly, rash, and fever. However, retinochoroiditis is the most common manifestation, occurring in 3/4 of cases. In congenital toxoplasmosis, the disease is bilateral in 65–85% of cases and involves the macula in 58%.

Some vertically transmitted infections, such as toxoplasmosis and syphilis, can be effectively treated with antibiotics if the mother is diagnosed early in her pregnancy. Many viral vertically transmitted infections have no effective treatment, but some, notably rubella and varicella-zoster, can be prevented by vaccinating the mother prior to ...
Zika virus is an arthropod-borne virus transmitted by mosquitos, and infection during pregnancy can lead to severe congenital abnormalities in a newborn. Congenital infection can lead to fetal growth restriction and CNS abnormalities, including microcephaly, ventriculomegaly and intracranial calcifications. [19]
Cytomegalic inclusion body disease (CIBD) also known as cytomegalic inclusion disease (CID) is a series of signs and symptoms caused by cytomegalovirus infection, toxoplasmosis or other rare infections such as herpes or rubella viruses. It can produce massive calcification of the central nervous system, and often the kidneys. [1]
The MMR vaccine is highly efficacious in preventing congenital rubella and is given routinely as a part of the pediatric vaccine schedule. [10] For neonates with congenital CMV infection, antiviral medication is given. Most commonly, valganciclovir or ganciclovir are used as first-line antiviral therapy for congenital CMV. [11]
