Chagas disease, a zoonosis caused by Trypanosoma cruzi infection and transmitted by triatomines, is considered one of the tropical diseases neglected by the World Health Organization, with direct and indirect social costs.

It directly impacts the lives of those affected due to its disabling potential for paid work and the performance of daily activities, causing financial dependence of the affected person either on their family members or the state.

Our team carried out an entomological study in 145 municipalities in the state of Bahia to identify vulnerable areas of Chagas disease transmission. We identified the triatomine species in which we performed tests to detect Trypanosoma cruzi.

Additionally, we determined the origin of the triatomine food source based on the type of DNA present in the intestinal contents of the vectors. We also identified the municipalities with the greatest vulnerability for transmission of Chagas disease using a mathematical model that took into account the species of triatomine, the presence of T. cruzi and the origin of the blood found in its intestinal contents, in addition to socioeconomic and demographic indicators.

You're welcome to join our Zoom seminar on 27 July from 12pm to 12.30pm. No registration required.
