Study Notes
Other Viral Infections and Hyperthermia
- Malformations from maternal infections with measles, mumps, hepatitis, poliomyelitis, echovirus, coxsackie virus, and influenza virus have been described.
- Prospective studies show the rate of malformation after exposure to these agents is low.
- Toxoplasmosis and syphilis cause birth defects.
- Poorly cooked meat from domestic animals, especially cats, and feces in contaminated soil can carry the protozoan parasite Toxoplasma gondii.
- A characteristic feature of fetal toxoplasmosis infection is calcification.
