In people with weakened immune systems, especially those with AIDS, symptoms of toxoplasmosis are often brain-related and severe. Also, if toxoplasmosis affects the eyes of a person with a weakened immune system, there may be blurred vision, spots in the field of vision, eye pain and extreme sensitivity to light.
Healthy people who become infected with Toxoplasma gondii often do not have symptoms because their immune system usually keeps the parasite from causing illness. When illness occurs, it is usually mild with flu-like symptoms (e.g., tender lymph nodes, muscle aches, etc.) that last for weeks to months and then go away.
