Serious fetal infections can be transmitted transplacentally or perinatally. Vaccination is a key prevention method as shown by the dramatic reduction of congenital rubella. Reducing the risk of toxoplasmosis, listeriosis and CMV in pregnancy requires knowledge of their epidemiology and appropriate prevention strategies in the absence of vaccines.
Primary infection with Toxoplasma gondii occurs following ingestion of active or inactive cysts. Sources of cysts include undercooked or raw meat (e.g. uncooked or dried meats), contaminated unwashed cooking surfaces and utensils, contaminated cat litter, soil and water supplies, unwashed soil-grown fruits and vegetables, unpasteurised milk, and less frequently, transplanted organs and blood products. Primary toxoplasmosis in pregnancy can lead to chorioretinitis, deafness, microcephaly, developmental delay, late onset of ocular defects, and stillbirth.
