Trypanosoma cruzi is a parasitic protozoan organism that causes Chagas disease in humans. It is transmitted to humans through the bite of infected triatomine bugs, also known as "kissing bugs." Chagas disease is a neglected tropical disease that affects millions of people in Latin America, and is a major public health concern in endemic regions. Research on Trypanosoma cruzi and Chagas disease focuses on understanding the biology of the parasite, its transmission, diagnosis, treatment, and prevention. Scientists are working to develop new diagnostic tools, drugs, and vaccines to combat the spread of this disease and improve outcomes for those affected by it. Additionally, researchers are studying the epidemiology and genetic diversity of Trypanosoma cruzi to better understand its transmission patterns and evolution.
