Congenital toxoplasmosis

Symptoms

What are the main symptoms of congenital toxoplasmosis

The main symptoms, known as the "classic triad", of congenital toxoplasmosis are:

  • Chorioretinitis (inflammation in the back part of the eye that can cause blindness)
  • Hydrocephalus (too much fluid around the brain)
  • Intracranial calcifications (bright spots in the brain seen on ultrasound that usually don't cause problems by themselves)

Other symptoms of congenital toxoplasmosis may be present when the baby is born, but can also take 20-30 years to appear. In fact, most newborn babies with congenital toxoplasmosis will not show any signs of the infection right away. Some symptoms might start to appear in early childhood, like intellectual and learning disabilities, and others might not occur until adulthood, such as hearing or vision loss. Studies have shown that up to 80% of people with congenital toxoplasmosis will develop learning disabilities or vision loss later in life.

Any there other diseases that look a lot like congenital toxoplasmosis?

Since the symptoms of congenital toxoplasmosis can be vague/non-specific (for example,low birth weight, seizures, feeding problems, or anemia), other infections can look like congenital toxoplasmosis. Infections with similar symptoms include congenital infection with herpes simplex virus, cytomegalovirus, and rubella virus.
