 Carlos Chagas discovered American tropanosomiasis, now known as Chagas disease, CD, in 1909. Since then, the disease has spread globally, becoming a major public health issue due to its high morbidity and mortality rates. The disease is caused by the protozoan tropanosoma cruzi, which is transmitted through the bite of triatamine bugs. Recent studies have shown that the disease can be found outside of its traditional endemic areas, including North America, Europe, and Asia. This suggests that the disease may be more widespread than previously thought. To combat the spread of the disease, researchers must focus on understanding the epidemiology of the disease, including the diversity of the parasites, vector species, and reservoirs. Additionally, efforts should be made to develop effective treatment prevention strategies.
