Toxoplasmosis

Toxoplasmosis is a parasitic infection. When contracted by a pregnant woman, toxoplasmosis can pose serious risks to the unborn baby. Simple precautions can reduce the chance of infection.

Pregnant women should avoid handling litter boxes and eating raw meat because the parasite may originate in cat feces or undercooked meat. One piece of undercooked contaminated London Broil is enough to cause it. If acquired during the first trimester of pregnancy, the infection can be devastating to an infant.

Toxoplasmosis affects the retina. Both eyes are usually involved. If the infection settles in the macula, the area of the retina responsible for central vision, good vision is lost forever.

When toxoplasmosis heals, it leaves a scar. The infection may recur years later, sometimes near a previous scar.

Treating toxoplasmosis with oral medications can be very effective. Pyrimethamine and sulfa drugs are the classic antibiotics although some doctors add or substitute clindamycin. Occasionally steroids, laser, or freezing (cryotherapy) treatments are prescribed.

Screening tests can identify women of childbearing age who are at risk of passing the infection to an unborn child.
