[Argentine Consensus of Congenital Toxoplasmosis]

Abstract

The mother-to-child transmission in Toxoplasma gondii infection occurs only when the infection is acquired for the first time during pregnancy. The prenatal and early postnatal diagnosis can only be achieved by serological testing. Serologic tests have different sensitivities, specificities and complexities, so that different tests in more than one blood sample are necessary for the diagnosis. Serological follow-up of the infants should be conducted during the first year of life or until the diagnosis of congenital toxoplasmosis can be ruled out. Treatment recommendations try to reduce the transmission rate and the risk of congenital damage. Congenital toxoplasmosis incidence rate is approximately 5 per 1000 births, but can be reduced to 0.5 per 1000 with an active screening program. The aim of this consensus group was to review the scientific literature on congenital toxoplasmosis and prepare a statement on prevention, diagnosis and treatment that should be implemented in our country.
