Which demographic is most affected by Chagas disease?

Chagas disease, caused by the parasite Trypanosoma cruzi, is predominantly found in rural areas of Latin America, making this group the most affected demographic. The transmission of the disease is often linked to the presence of triatomine bugs, which are more prevalent in rural regions where housing conditions may facilitate the bug's habitation.

In rural settings, many individuals are exposed to these vectors through inadequate housing and sanitation conditions. Additionally, these areas may lack access to healthcare and resources for prevention and treatment. While infants and older adults can be severely affected if they contract the disease, the highest rates of infection and the most significant burden of disease occur in populations living in rural Latin America.

Understanding the geographic and socioeconomic factors that influence the spread of Chagas disease highlights the importance of targeting public health interventions and resources in these specific communities to address and mitigate the impact of the disease effectively.
