Elimination of vector-borne transmission of Chagas disease

First report of Trypanosoma cruziinfection in naturally infected dogs from southern Bahia, Brazil

“…The result of this control program was the widespread reduction of T. cruzi transmission by this triatomine bug, considered the most important vector of Chagas disease in the past VINHAES, 1999;DIAS, 2006). In 2006, the Pan American Health Organization (PAHO) certified the interruption of T. cruzi transmission by T. infestans in Brazil (BRASIL, 2006).…”

Monitoring the domiciliary and peridomiciliary invasion process of Triatoma rubrovaria in the State of Rio Grande do Sul, Brazil

“…Thus, T. infestans was incriminated as the main vector of Chagas disease (Silveira & Vinhaes 1999). The beginning of the control interventions in RS is represented in Figs 6 and 7 referring to the municipalities of Quaraí and Santana do Livramento, which show an outstanding inverse relation in the years 1976-1980, when the numbers for T. infestans were high and for T. rubrovaria were low.…”

“…4, showing a marked decline in the numbers of domestic T. infestans encountered from 1983 up to 1986-1987 when the national campaign was interrupted by the demands of the 1986 dengue outbreaks. Control activities resumed in 1990-1991 in line with the 'Southern Cone Initiative' against Chagas disease (Schofield & Dias 1998), with a steady decline in the frequency of domestic T. infestans throughout Brazil up to the present (Silveira & Vinhaes 1999).…”

Biology, diversity and strategies for the monitoring and control of triatomines - Chagas disease vectors

“…The precise mapping of their occurrence, domestic infestations and the natural infection rates for the different triatomine species is critical for understanding the challenges and threats posed by vectorial transmission (Silveira & Vinhaes 1999, Silveira 2000, Costa et al 2002, López-Cardenas et al 2005. Understanding their host searching behaviour and activity patterns (Guerenstein & Lazzari 2009) as well as their choice of environments (Guarneri et al 2002(Guarneri et al , 2003 is also necessary.…”
