The Triatomines of Northern Peru, with Emphasis on the Ecology and Infection by Trypanosomes of Rhodnius ecuadoriensis (Triatominae)

Abstract

Information on the distribution and synanthropic behaviour of triatomines is essential for

New focus of active transmission of Chagas disease in indigenous populations in the Peruvian Amazon basin

“…The ACD focus we present in this study shows more intense active transmission than reported in Pozuzo (Pasco department) in the selva central 8 or in the rural area of Loreto department, where sporadic transmission has been reported 5 . Instead the areas mentioned in the present study resemble high transmission areas in the basin of the Utcubamba River 12 , located in the upper part of the Marañón River, where the main vector, Panstrongylus herreri, resides 13 .…”

Epidemiology of American trypanosomiasis in northern Peru

“…carrioni, Panstrongylus chinai, P. herreri and Rhodnius ecuadoriensis in northern Peru are sometimes naturally infected with Try. cruzi and often invade dwellings in many localities (Cáceres et al, 2002;Cuba Cuba et al, 2002). In addition, acute cases of Chagas disease have been detected in the north-eastern region, and blood donors who are seropositive for Try.…”

Geographical distribution and intra-domiciliary capture of sylvatic triatomines in La Convención province, Cusco, Peru

“…It has been previously reported in Loreto, Ucayali, San Martín, Madre de Dios, and Junín; in the first four it has been found infected by T. cruzi 5,10 ; although, it has been considered as of little epidemiological importance for Peru 6 . However, the finding of domiciled colonies both in La Convención (Cusco) and in Lamas (San Martín) can change the status of this species.…”

“…In Peru, the number of people estimated to be infected by T. cruzi is between 650 000 and 670 000 6 . The endemic area is stratified in three eco-epidemiological regions (Southwest, Andean and Amazon) 2 .…”
