Seroprevalencia de citomegalovirus y toxoplasma gondii en población sana menor de 30 años, en Santiago de Chile / Seroprevalence of cytomegalovirus y toxoplasma gondii in health population under 30 years old at Santiago, Chile

RESUMO

Subjects and methods: The prevalence of IgG antibodies against Cytomegalovirus and Toxoplasma gondii were studied in 560 subjetcs under 30 years old, using and ELISA technique. Age, socioeconomic level, breast feeding, assistance to nurseries and number of family members were considered as risk factors for these infections. Results: Infection by Cytomegalovirus and Toxoplasma gondii were studied in 560 subjetcs under 30 years old, using an ELISA technique. Age, socioeconomic level, breast feeding, assistance to nurseries and number of family members were considered as risk factors for these infections. Results: Infection by Cytomegalovirus had a global prevalence of 60 percent. It showed an epidemiological pattern of late adquisition in high socioeconomic levels and a pattern of early infection in medium and low socioeconomic levels. 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:
