Chagas disease is one of the deadliest parasitic diseases in the world. More than 10 million people are affected by it, usually in America. It kills about 50,000 people in South America each year. A diagnosis has been a main point in the fighting the infection, it hasn't been achieved yet—Momar Ndao and his associates at the Research Institute of the McGill University Health Centre in Montreal had their results published in the Journal of Clinical Microbiology. They have reported their success in making a process of diagnosis and others have failed.

Chagas disease, also known as American trypanosomiasis, which is in South America and southern Central America, happens by the parasite Trypanosoma cruzi. The disease is usually sent through the bite of an infected insect. The symptoms are varied, but as the disease moves on, serious chronic symptoms can start to happen, like heart disease and malformation of the intestines. Some people affected may not have symptoms for years, which makes diagnosis difficult.

Chagas disease can also be sent from mother to unborn child and can go on through many generations without symptoms. If a mother gave birth to someone in North America who was infected can send the disease to their child without traveling. They might also unknowingly donate infected blood. There is an fast need for action on this disease as it is under-diagnosed and there is no effective treatment.
