PERFIL EPIDEMIOLÓGICO DA TOXOPLASMOSE NO MUNICÍPIO DE ANÁPOLIS NO PERÍODO DE 2001 A 2005

Abstract

Toxoplasmosis is a zoonosis with universal distribution. The protozoan Toxoplasma gondii is responsible for the pathology, which infects fowls and mammals including men. The present study is an epidemiologic inquiry that has as objective to establish epidemiologic profile of toxoplasmosis in Anápolis County, delineating periodic incidences and the prevalence. The epidemiologic inquiry has as the aim acquires data which lead primary, secondary and tertiary prevention for toxoplasmosis more efficient and effective in Anápolis County and other cities. Results of serologic assays for antibodies anti-toxoplasma of immunoglobulins (Ig) M and G class, carried out by public laboratories of Anápolis were used. Results correlated with sex and laboratorial techniques during five years (2001 January to 2005 December) were used. Term of free and revealed consent was sign by six laboratories which participated of research. In all laboratories was analyzed 2399 exams, but 56 was considered missing cases, therefore, left 2343 exams. The data was submitted to descriptive statistic analysis, which showed absolute results and percentiles. In Anápolis County the acute toxoplasmosis prevalence was 11% in the group with antibodies antitoxoplasma IgM+ IgG- combination. Cases prevalence which has previous contact with Toxoplasma gondii followed by acquired immunity was 3% in the group with antibodies anti-toxoplasma IgM- IgG+ combination. Cases prevalence, with exclusion of acute toxoplasmosis diagnosis, without discard previous infection possibility, was 60% in the group with antibodies anti-toxoplasma IgM- IgG+ combination. Cases prevalence with exclusion of acute toxoplasmosis and previous infection possibility in the group IgM- IgG- was 25%. Indeterminate cases have a prevalence of 1%. In gender variable female corresponded to 93,42%. The laboratorial technique most used was immunefluorescence (IFI), representing 66,75% of all exams. In conclusion cases prevalence with exclusion of acute toxoplasmosis diagnosis, without discard previous infection possibility is in agreement with literature; global prevalence was undertook without consider ages; was impossible to know toxoplasmosis positivity in pregnancy; acute toxoplasmosis rate was 11%.
