In simple words: Congenital toxoplasmosis is an infection that a baby can get before birth from their mother. It is caused by a parasite. The infection can cause problems like brain swelling, small head size, hearing loss, seizures, and developmental delays. The baby might also have fever, rash, and an enlarged liver or spleen.

Congenital toxoplasmosis is a parasitic infection caused by Toxoplasma gondii, transmitted from mother to fetus.The severity of the condition correlates with the gestational age at infection, with earlier infections posing greater risk of severe neurological damage. Manifestations can include hydrocephalus, microcephaly, deafness, seizures, intracranial calcifications, and psychomotor retardation. Systemic signs like fever, rash, and hepatosplenomegaly may also be present at birth.

Example 1: A newborn presents with hydrocephalus, chorioretinitis, and intracranial calcifications. Serological testing confirms congenital toxoplasmosis., An infant born to a mother with acute toxoplasmosis during pregnancy exhibits seizures and hepatosplenomegaly. Congenital toxoplasmosis is diagnosed., A seemingly healthy newborn is found to have asymptomatic congenital toxoplasmosis through routine screening. Long-term monitoring for potential complications is initiated.

Documentation should include maternal and infant serological testing results, imaging studies (e.g., ultrasound, CT, MRI) demonstrating characteristic findings, and clinical presentation of the infant (e.g., hydrocephalus, chorioretinitis, seizures, etc.).
