More Videos Story highlights In most cases, Chagas symptoms are absent or mild and unspecific A new study has found that infection more than doubles a person's risk of death. Their name stems from the fact that they like biting humans around their lips and faces as they sleep, after which they defecate into the wound with feces that harbor an infectious parasite, Trypanasoma cruzi.
The parasite then enters the bloodstream and causes Chagas disease, also known as trypanosomiasis. Though the disease is generally considered to be mild or even asymptomatic among most, a new study has found that deaths fueled by the infection are much more common than we know -- and are going unrecognized.
Could one discovery take on three deadly parasites? Ligia Capuani, an infectious disease researcher at Faculdade de Medicina da Universidade de Sao Paulo, in Brazil, who led the research. Diagnosis is a challenge in many parts of Central and South America, where the disease is most prevalent, with people often finding out that they are infected only when they donate blood, explained Capuani. The kissing bugs behind the disease have also been reported in 25 US states, with the largest concentration in the South. The research team analyzed data from more than 8, people who donated blood between and and compared mortality among people who tested positive and negative for infection with T.
