Abstract. The Gran Chaco and
adjacent areas extending over Bolivia,
Argentina and Paraguay
are hyperendemic for Chagas disease and the heart of the distribution of Triatoma infestans. Despite an ongoing
elimination campaign, vector-mediated transmission persists in much of the Gran Chaco and insecticide resistance has recently
emerged. The Gran
Chaco is the last
frontier in the elimination of T.
infestans, and therefore is a priority of the Southern Cone
Initiative. We propose to bring together research groups from the three
countries in collaboration with local vector control programs, community groups
and other associated institutions to conduct transdisciplinary research on the
eco-epidemiology and control of Chagas disease vectors on geographic scales
ranging from local to regional. We will investigate the process of house
reinfestation in response to vector control actions in a multisite, prospective,
and participatory study. We will scrutinize societal determinants of
infestation, with special attention to knowledge, gender-based attitudes and
practices of the affected populations in relation to T. infestans. The project
is expected to i) elucidate the mechanisms underlying the reinfestation process;
ii) provide vector control programs and the affected communities with improved
tools and strategies that will enhance the effectiveness of current control
efforts; iii) contribute with new knowledge at levels that span from diagnosis
to prediction of reinfestation risk and prescription of targeted control
measures; iv) elaborate an ecosystem and community-based model that integrates
practical preventive and remedial procedures as well as tools to enhance a
sustainable surveillance strategy. The project involves specific training and
capability strengthening of participating members through workshops, will help
coordinate research activities in the Gran Chaco, and will also strengthen the
capacity of indigenous and creole ('criollo') communities to cope with Chagas
disease. Inclusion of members of the respective National Health Administrations
will facilitate the transfer of relevant results.
