A 22-year-old has just been diagnosed with toxoplasmosis. You try to determine what her risk factors were. The highest risk association is which of the following?
- Eating raw meat
- Eating raw fish
- Owning a dog
- English nationality
- Having viral infections in early pregnancy
Toxoplasmosis, a protozoal infection caused by T. gondii, can result from ingestion of raw or undercooked meat infected by the organism or from contact with infected cat feces. The French, because their diet includes raw meat, have a high incidence. The incidence of toxoplasmosis in pregnant women is estimated to be 1 in every 150 to 700 pregnancies. Infection early in pregnancy may cause abortion; later in pregnancy, the fetus may become infected. A small number of infected infants develop involvement of the central nervous system or the eye; most infants who have the disease, however, escape serious clinical problems.
