Quite a surprise

Prenatal testing could spare babies from toxoplasmosis complications

A study from Stanford finds strong reason for routine testing of toxoplasmosis in the US:

Their research found much higher rates of serious brain and eye disease among U.S. infants with congenital toxoplasmosis than among similar infants in Europe, where the prenatal testing is routine....
Eighty-four percent of the North American infants studied had serious complications of the parasitic infection, including calcium deposits in the brain, water on the brain and eye disease that caused visual impairment or blindness. By contrast, few European infants had these problems – for instance, about 17 percent of French infants with the infection develop complications.

“It was a shock,” said Jose Montoya, MD, the study’s senior author and an associate professor of Medicine in Infectious Diseases at Stanford. “We were dismayed to see so many little ones with severe eye disease, hydrocephalus and brain calcifications.”

The reason for the different outcomes between affect US and European babies:
...effective medications exist to prevent mother-to-child transmission of the Toxoplasma gondii parasite – and babies who receive these drugs in utero have much lower rates of complications than the infants in Montoya’s study, whose mothers did not get the prophylactic meds.
The test is cheap too. I wonder if it is done in Australia?
