Results: Infection by Cytomegalovirus and Toxoplasma gondii were studied in 560 subjetcs under 30 years old, using an ELISA technique.

Eighty to 90 percent of sera were positive for the infection in adult subjetcs of the three socioeconomic levels. There was a positive correlation between the duration of breast feeding and the frequency of Cytomegalovirus infection. Infection by Toxoplasma gondii had a global prevalence of 24.6 percent. The rates of susceptible individuals were 80 and 50 percent in high and medium-low socioeconomic levels respectively. Conclusions: The knowledge about the frequency of these infections in high risk populations such as women during their reproductive years and immunodepressed individuals, will allow the implementation of preventive measures
