Patterns of vector species richness and species composition as drivers of Chagas disease occurrence in Brazil

Abstract: Chagas disease represents one of the major health issue in Latin America. Epidemiological control is focused on disease vectors, so studies on the ecology of triatomine vectors constitute a central strategy. Recently, research at large spatial scale has been produced, and authors commonly rely on the assumption that geographical regions presenting good environmental conditions for most vector species are also those with high risk of infection. In the present work, we provide an explicit evaluation for this ass… Show more

“…We identified manuscripts on the topic of infectious disease, including both outbreaks and emergence of directly transmitted and vector-borne infections, relevant to biodiversity. Selected studies investigated the zoonoses bartonellosis [12], bovine tuberculosis [13,14], echinococcosis [15], hantavirus [16][17][18][19][20][21][22], leptospirosis [23], Lyme disease [18][19][20][21][22] and West Nile virus [18,21,[24][25][26][27], and vector-borne diseases Chaga's disease [28], malaria [18,29,30], schistosomiasis [12,18,31] and tick-borne encephalitis [32].…”

“…Based on the reviewed body of evidence linking biodiversity to human infectious and non-communicable disease, a future research agenda to determine the net effects of diversity must include integrative approaches to combine different perspectives [27,52]. A recent study on Chaga's disease developed two species-distribution models and combined them with national health data to analyse a causality assumption and investigate consistency across scales [28]. Although species composition better predicted the observed pattern of Chaga's disease occurrence than did species richness, only 5% of the variability was explained.…”

“…In fact, many vectorborne diseases are transmitted between hosts via multiple vectors. For instance, malaria has more than four mosquito vectors (Hoi et al, 2020(Hoi et al, , 2022, West Nile virus has 7-16 mosquito vectors (Roche et al, 2013), and Chagas disease has up to 10 triatomine vectors (Eduardo et al, 2018). Although vector richness may strongly influence the pathogen transmission (Brooks & Zhang, 2010), the effect of vector richness on disease risk is poorly understood.…”
