Toxoplasma gondii infection in pregnant women can be manifested by symptoms in the pregnant woman herself and symptoms in the fetus. 1. Symptoms of Toxoplasma gondii infection in pregnant women are similar to the symptoms of Toxoplasma gondii infection in ordinary people, such as fever, enlarged lymph nodes, and complications of pneumonia. If the infection causes lesions in the central nervous system or optic nervous system, symptoms such as epilepsy, headache, loss of limb movement, and vision loss may occur. 2. The fetus can be infected with Toxoplasma gondii through the placenta, which can lead to delayed or stagnant fetal growth and development, resulting in miscarriage. It can also cause lesions in the central nervous system of the fetus, such as abnormal brain development, stagnation or anencephaly. If it causes optic neuropathy in the fetus, it can result in microphthalmia, anophthalmia, or ocular choroiditis. In conclusion, pregnant women with Toxoplasma gondii infection during pregnancy need to go to the hospital in time and cooperate with the doctor for active treatment.
