What are TORCH infections?
TORCH infections are a group of infections that can affect a developing fetus during pregnancy. The term "TORCH" is an acronym for Toxoplasmosis, Other (syphilis, varicella-zoster, parvovirus B19), Rubella, Cytomegalovirus, and Herpes simplex. These infections can be transmitted from the mother to the fetus and may lead to serious congenital abnormalities or other complications. It's important for pregnant individuals to receive proper prenatal care and screening to detect and manage TORCH infections.
What are the TORCH diseases?
The TORCH diseases correspond to the infections included in the TORCH acronym:
● Toxoplasmosis:
Caused by the Toxoplasma gondii parasite.
● Other infections:
This category includes various infections such as syphilis, varicella-zoster (chickenpox), parvovirus B19, and others.
● Rubella:
Caused by the rubella virus.
● Cytomegalovirus (CMV):
Caused by the cytomegalovirus.
● Herpes simplex:
Caused by the herpes simplex virus, which includes herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2).
These infections can pose a risk to a developing fetus if a pregnant individual becomes infected, potentially leading to congenital disabilities or other complications. Prenatal care and screening are crucial to detect and manage these infections during pregnancy.
How does my baby get a TORCH infection?
A baby can acquire a TORCH infection if the mother is infected with one of the TORCH pathogens during pregnancy. The transmission can occur in various ways:
■ In utero (during pregnancy):
The infection can pass from the mother to the fetus through the placenta, exposing the developing baby to the infectious agent.
■ During childbirth:
Some TORCH infections, particularly herpes simplex virus, can be transmitted to the baby during delivery if the mother is shedding the virus.
■ Breastfeeding:
While breastfeeding is generally beneficial, certain TORCH infections like cytomegalovirus (CMV) can be transmitted through breast milk if the mother is infected.
■ Contact with infected bodily fluids:
After birth, a baby can contract TORCH infections through contact with infected saliva, urine, blood, or other bodily fluids.
It's important for pregnant individuals to receive proper prenatal care, including screening for TORCH infections, and for healthcare providers to manage and treat these infections promptly to reduce the risk of transmission to the baby.
