Abstract

This paper is a short review of the discovery of Chagas disease and the current information of the epidemiological and clinical aspects of the disease observed in Peru. With the discovery of Trypanosoma cruzi in the blood of a child in 1909, the isolation of the etiologic agent in experimental animals and the finding of similar parasites in the intestinal content of triatomines, Carlos Chagas determined the parasite's life cycle and, clinical symptoms of this new entity designated as Chagas disease. Eight years after Dr Carlos Chagas discovery (1917), Dr. Edmundo Escomel born in Arequipa, reported the presence of Triatoma infestans in the valleys of Arequipa department and after two years the first human case of Chagas disease from Madre de Dios. In Peru, have been described 19 species of triatomines, and several studies show guinea pig "cuy" as the most important reservoir of the parasite. The endemic areas are present in the south, north and northeast, mainly the Amazonian area. Recently, Tacna has been declared free of vectorial transmission and we hope others parts of the country could receive similar certification. [ABSTRACT FROM AUTHOR]

Abstract

Objectives. To determine the prevalence of Trypanasoma cruzi antibodies among the population under 18 years of age in the state of Veracruz, Mexico, and to identify risk factors associated with housing conditions and vector presence and distribution. Methods. A cross-sectional, epidemiological study of the population under 18 years of age living in 10 of the 11 health districts of the state of Veracruz, Mexico, from 2000 to 2001. Presence of T. cruzi antibodies was determined by hemagglutination inhibition test (HAl) and enzyme-linked immunosorbent assays (ELISA) of serum samples spotted on filter paper, and confirmed by HAl, ELISA, and indirect immunofluorescence assay (IFA) on serum samples. A questionnaire was administered to determined housing conditions, and entomological indices for triatomines were calculated for both the intra- and peridomiciliary areas. The results were analyzed using bifactorial and multifactorial unconditional logistic regression. Results. Of the 150 individuals presenting an initial reaction, 14 were confirmed positive (5 by HAl, ELISA and IFA; 6 by HAl and ELISA, and 3 by ELISA and IFA), for a total prevalence rate of 0.91% (95% CI: 0.85–0.94). All of the confirmed-positive cases were from five of 14 health districts, with the Tuxpan district having the highest prevalence rate: 5.2% (95%CI: 1.2–9.0). Risk factors included having noticed cracks in the house walls and gaps in the roof. The only species of vector captured was Triotoma dimidiata. The entomologic indices for infestation, colonization, and natural infection were: 10.9%, 50.0%, and 9.0%, respectively. Conclusions. Active, vector-borne transmission of T. cruzi was confirmed in the state of Veracruz, Mexico, with an overall antibody seroprevalence rate of 0.19% among the population under 18 years of age. Seroprevalence rates among this segment of the population, which serves as a sentinel group, should be closely monitored to determine if more stringent methods of vector control and epidemiological surveillance are needed.
