Epidemiology of Chagas disease in San Roque Corrientes. Triatomine infestation and human seroprevalence
This investigation was aimed to evaluate triatomine colonization in domestic and extradomestic ecotopes located around a palm community, to determine triatomines infection index and to obtain human seroprevalence rates. Samplings were performed in spring 1998 and summer 1999 in Colonia Laurel, Depar...

A total of 122 T. infestans of all age classes were collected and T. cruzi infection was recorded in 16.7%. Triatoma infestans was confirmed as the predominant species in the domicile and T. sordida in the peridomicile.

Seropositives percentages increased with age and reached 66.6% in older than 40 years. Presence of T. infestans, human seroreactivity to T. cruzi, ≤ 4 year old seropositives and precarious life conditions prove that this endemic disease is still a problem in the studied area.
