What is the cause of a pregnant woman with toxoplasmosis giving birth to a child with cogenital defect?

Answer 1

A pregnant woman with toxoplasmosis can pass the Toxoplasma gondii parasite to her fetus, particularly if she becomes infected during or shortly before pregnancy. This transmission can disrupt fetal development, leading to congenital defects such as hydrocephalus, chorioretinitis, or intracranial calcifications. The severity of the defects often depends on the timing of the infection, with later infections generally causing less severe outcomes. Early detection and management can help mitigate risks to the developing fetus.
