An acute Chagas disease infection with swelling of the right eye (Romaña's sign) Chagas disease occurs in two stages: an acute stage, which develops one to two weeks after the insect bite, and a chronic stage, which develops over many years. [2] [4] [16] The acute stage is often symptom-free. [2]
Carlos Chagas with his sons, Evandro Chagas and Carlos Chagas Filho. After the death of his mentor in 1917, Chagas accepted Cruz's directorship of the institute, a post he held until his own death in 1934. [25] From 1920 to 1924, he became the director of the Department of Health in Brazil, the set up of which he initiated.
There are approximately 15 million people infected with Chagas disease. [18] Morbidity rates are higher for immunocompromised individuals, children, and the elderly, but can be very low if the disease is treated early. [38] Chagas disease does not kill victims rapidly, instead causing years of debilitating chronic symptoms.
The disease has spread to the U.S. in the last 40 years, says the American Heart Association, but many doctors are unfamiliar with how to diagnose and treat it. ... 800-290-4726 more ways to reach us.

Cattle can also act as a reservoir in areas where disease incidence is lower. [13] Trypanosoma brucei gambiense is the second type of protozoan which usually results in more chronic disease patterns. [15] Its main reservoir is the cattle populations. Although it is also fatal, death can take months or years to occur. [17]
Arguments for the Chagas hypothesis were mainly his gastric symptoms and some of his nervous signs and symptoms (caused in Chagas by an imbalance of the autonomic nervous system), malaise and fatigue, as well as his ultimate cause of death, which seems to have been chronic cardiac failure (present in ca. 20% of Chagas patients, with ...
Given the 100 million people at risk and Chagas disease's disease burden, funding for R&D to improve treatments is extremely low, making it one of the most neglected of the neglected diseases. In 2007, less than US$1 million (0.04% of R&D funding dedicated to neglected diseases) was spent on the development of new drugs for Chagas disease. [7] [8]
