Vigilância epidemiológica em doença de Chagas

Abstract

Chagas disease still constitutes an important medical problem in affected countries. In some, the extent of the disease is still unknown and control programs have not been implemented. In others the disease has been reduced due to regular control programs and other eco

Seroprevalence of Chagas disease in schoolchildren from two municipalities of Jequitinhonha Valley, Minas Gerais, Brazil; six years following the onset of epidemiological surveillance

“…In general, considering the universe of schoolchildren evaluated (07-14), the general seropositivity was predominant in older children (09-14), with 5/6 of them with 11 to 14 years. However, when considering the two municipalities in separate analysis, Berilo showed seropositivity predominance in younger children (09-13) while José Gonçalves de Minas showed evidence of older children (11)(12)(13)(14). …”

“…The epidemiological surveillance of Chagas disease, in areas where the anti-vectorial program was implemented is extremely important to guarantee the successful control of disease transmission 14 . Still, a well accomplished epidemiological surveillance become even more important in regions where the vector species involved in the transmission are often observed in peridomicile.…”

“…In this context, the accuracy and well-defined improvement of local Health Public System (SUS) as well as the generation of qualified human resources and competences are of major relevance as previously suggested by DIAS 14 . Meanwhile, we are working with the health team in Berilo.…”

Occurrence and distribution of triatomines (Hemiptera: Reduviidae) in municipalities of the Northeastern region of Minas Gerais State, Brazil

“…However, these activities were interrupted owing to political-administrative issues, thus contributing to re-establishment of intradomiciliary triatomine colonies. This imposed a reactivation of vertical actions by the national Chagas Disease Control Program (CDCP) in 1982, carried out by Superintendência de Campanhas de Saúde Pública (4) . Since the late 1990s, entomological surveillance has been a responsibility of the municipalities.…”

“…Regarding the capture site, 57.2% (6,401) of the insects were captured at the peridomicile; 36.7% (4,102), in the intradomicile; 2.2% (245), at other places, and for 3.9% (439) of the insects, the site of capture was unknown. The adult specimens were captured mainly in the intradomiciliary environments, while immature forms prevailed in the peridomicile.…”
