This is a rare infection caused by a parasite that spreads primarily via cats or unwashed fruits and vegetables. Most people never notice they have been infected. If you develop symptoms, the most common ones are fever, muscle aches, swollen lymph nodes and fatigue. Toxoplasmosis is treated with antibiotics. There is a risk that the infection will pass to the baby and, if this happens in early pregnancy, the baby can develop severe defects, or the infection will cause a miscarriage.
When you are pregnant, do not clean a litter box, wash fruits and vegetables well and, if you work in a garden, remember to carefully wash your hands since the infection can be transferred via soil.
