title: [The National Toxoplasma Survey. I. Prevalence by sex and age. Cuba, 1987].
abstract: A national seroepidemiological survey was carried out to assess the prevalence of anti-Toxoplasma gondii antibodies. 8863 samples taken in filter paper through the ELISA test were analyzed and 29.70% positivity was obtained. No significant differences were found regarding sex. Seropositivity increased with age, up to the 20-29 age group, with a stable behavior in over-29-year age groups. The highest percentage of annual change was registered in the 5-9 age group (1.62%). This parameter reached 0.93% in the women's 25-29 age group.
