TORCH Infections in Paediatrics Complete Guide to Congenital Toxoplasmosis Rubella CMV Herpes Diagnosis Management
TORCH infections are a major group of congenital infections that affect newborns and infants. The TORCH complex includes toxoplasmosis, other infections such as syphilis and varicella, rubella, cytomegalovirus, and herpes simplex virus. These infections are transmitted from mother to fetus during pregnancy or delivery and can lead to serious complications including developmental delay, congenital anomalies, hearing loss, vision impairment, and neurological damage.

This detailed guide explains TORCH infections in paediatrics including causes, pathophysiology, risk factors, clinical features, characteristic findings, investigations, diagnosis, treatment options, and prevention strategies. It also covers the classic presentations of congenital toxoplasmosis, congenital rubella syndrome, cytomegalovirus infection, neonatal herpes infection, and congenital syphilis.

Understanding TORCH infections is essential for medical students, paediatricians, neonatologists, and healthcare professionals involved in maternal and child health. Early diagnosis, proper maternal screening, and timely treatment can significantly reduce complications and improve neonatal outcomes. This resource provides comprehensive knowledge for academic learning, clinical practice, and exam preparation in paediatrics.

Which TORCH infection is the most common congenital viral infection?
Cytomegalovirus infection is the most common congenital viral infection and a leading cause of non genetic sensorineural hearing loss in children.
How are TORCH infections diagnosed in newborns?
Diagnosis is made using serological tests for TORCH IgM antibodies, PCR tests for viral DNA or RNA, imaging studies such as ultrasound or CT scan of the brain, ophthalmologic examination, and hearing screening.
What is the treatment for congenital cytomegalovirus infection?
Symptomatic congenital cytomegalovirus infection is treated with antiviral medications such as ganciclovir or valganciclovir to reduce complications including hearing loss.
How is congenital toxoplasmosis treated?
Congenital toxoplasmosis is treated with a combination of pyrimethamine, sulfadiazine, and folinic acid to eliminate the parasite and reduce bone marrow toxicity.
How can TORCH infections be prevented during pregnancy?
Prevention includes rubella vaccination before pregnancy, avoiding undercooked meat, practicing good hygiene, avoiding contact with cat litter, screening during pregnancy, and proper management of maternal infections.
