The little known Chagas disease is becoming "the new AIDS of the Americas," according to researchers.
They say the shares many similarities with AIDS; Chagas disease is caused by blood-sucking insects, is spread through blood, symptoms take a long time to develop or may in fact never show, but up to a quarter of infected carriers eventually develop potentially fatal enlarged hearts or intestines.
Chagas also has a long incubation time, and is hard or impossible to cure, and because it is a "disease of the poor," little money is spent on prevention or finding new treatments.
The disease infects up to 8 million people in the Americas, and while those sufferers are mainly located in Central America, South America, and Mexico; there are 300,000 people with the disease in the U.S. and the number of carriers is also rising in Europe through immigration from Latin America.
