Congenital infections,
also known as TORCH infections, are a class of microorganisms that can
damage a developing foetus by crossing the placenta. Toxoplasmosis, Other (syphilis,
varicella, parvovirus B19), Rubella, Cytomegalovirus (CMV), and Herpes simplex
virus (HSV) are all referred to as TORCH. These diseases are
especially problematic because they can cause serious harm to the foetus while
remaining asymptomatic in the mother.
The timing of the mother's
illness during pregnancy affects the impact of TORCH infections.
While later infections may cause growth restriction, hearing loss,
vision impairment, or developmental delays, early exposure
frequently results in miscarriage, stillbirth, or severe congenital
abnormalities. For instance, CMV is a major cause of sensorineural
hearing loss in children, while rubella can result in congenital heart
abnormalities and cataracts.
The diagnosis process
commonly employs maternal serology, foetal ultrasonography, and newborn
screening. Vaccinations against diseases like rubella, safe eating habits
to prevent toxoplasmosis, and regular prenatal care are examples of
preventive measures. Reducing long-term consequences requires early detection
and supportive care, such as timely interventions and appropriate
medical follow-up for affected infants.
In the end, TORCH infections emphasise the significance of prenatal screening and maternal health since safeguarding the mother directly protects the child's future.
