CHAGAS IS A COMPLEX PROBLEM TO ADDRESS
Chagas is a complex problem
There is very high transmission in some localities and very low in others. These localities differ in:
Genetics of the insect vector and parasite
In addition, these factors are constantly changing due to changes in land use, including deforestation, and climate change. Why do we have high transmission in some localities and little to no transmission in others? Our collaborative research is aimed at answering this question and developing a model to direct evidence-based control strategies.
Results of our previous studies show that house condition, especially the degree of plastering on the walls is critical factor in risk of Chagas transmission. Ecohealth improvements shift blood sources of insect vectors away from humans, result in reduced infestation, and lower T. cruzi prevalence in the insect vectors.
