“…However, the fi rst report of acute CD occurred in 1980 in São Paulo de Olivença (24) while the fi rst report of an acute case in the state capital, Manaus, occurred in 1994 in the city's urban area (25) . Since then, there have been increasingly frequent records of acute and chronic cases, mainly in the countryside (17) (26) (27) (28) (29) (30) (31) (32) (33) (34) (35) (36) . The fi rst xenodiagnosis performed in a chronic patient from the upper Rio Solimões region was made in 1999, from a colony of Triatoma maculata found inside the houses and chicken coops of the Macuxi Indians in the municipality of Normandia, State of Roraima (37) .…”

27www.scielo.br/rsbmt I www.rsbmt.org.br Revista da Sociedade Brasileira de Medicina Tropical 48(Suppl I):27-33, 2015http://dx.doi. org/10.1590/0037-8682-0258-2013 Review Article ABSTRACT Chagas disease (CD) is a parasitic infection that originated in the Americas and is caused by Trypanosoma cruzi.In the last few years, the disease has spread to countries in North America, Asia and Europe due to the migration of Latin Americans. In the Brazilian Amazon, CD has an endemic transmission, especially in the Rio Negro region, where an occupational hazard was described for piaçaveiros (piassaba gatherers). In the State of Amazonas, the fi rst chagasic infection was reported in 1977, and the fi rst acute CD case was recorded in 1980. After initiatives to integrate acute CD diagnostics with the malaria laboratories network, reports of acute CD cases have increased. Most of these cases are associated with oral transmission by the consumption of contaminated food. Chronic cases have also been diagnosed, mostly in the indeterminate form. These cases were detected by serological surveys in cardiologic outpatient clinics and during blood donor screening. Considering that the control mechanisms adopted in Brazil's classic transmission areas are not fully applicable in the Amazon, it is important to understand the disease behavior in this region, both in the acute and chronic cases. Therefore, the pursuit of control measures for the Amazon region should be a priority given that CD represents a challenge to preserving the way of life of the Amazon's inhabitants.

-Torres: concepción y diseño del estudio Oneida Castañeda-Porras: organización del manuscrito Todos los autores participaron en el análisis e interpretación de los datos y en la escritura del manuscrito. Resultados. Se registraron 552 personas expuestas y se confirmaron por laboratorio 40 casos (7,2 %); siete casos se dieron en mujeres (17,5 %) y 33 en hombres (82,5%), es decir, en una relación de 1:5. La edad promedio fue de 39,1 (± 10,8) años, la tasa de ataque, de 7,2 %, y la letalidad, de 5 % (2/40). Los signos y síntomas incluyeron fiebre en el 100 % de los casos, cefalea en el 80 %, mialgias y artralgias en el 65 %, edema facial en el 55 %, y dolor abdominal en el 37,5 %. El tiempo promedio de incubación fue de 17 (3-21) días. El índice de infestación de Rhodnius prolixus fue de 3,3 % en el domicilio y de 2,2 % en el peridomicilio. En los cinco restaurantes inspeccionados, se encontraron condiciones sanitarias deficientes y alimentos con niveles de contaminación microbiológica inaceptables. Por último, un perro y dos zarigüeyas fueron positivos para los anticuerpos IgG en la prueba ELISA. Conclusiones. Mediante el análisis de las características epidemiológicas, ambientales y sanitarias, se confirmó un brote agudo de enfermedad de Chagas por exposición ocupacional y de posible transmisión oral, que podría ser el de mayor proporción reportado hasta la fecha en Colombia.Palabras clave: enfermedad de Chagas/transmisión; Trypanosoma cruzi; salud laboral; epidemiología descriptiva.
