Resumen:
Chagas disease is caused by Trypanosoma cruzi (T. cruzi), and humans mainly acquire the parasite by exposure to contaminated feces from hematophagous insect vectors known as triatomines. Triatoma virus (TrV) is the sole viral pathogen of triatomines, which are the vectors of Chagas disease. TrV is transmitted by the fecal-oral route because, as happens with T. cruzi, the infected insects release the virus when defecating during blood uptake. In this work, we analyzed the occurrence of anti-TrV antibodies in human sera from countries endemic or non-endemic for Chagas disease. Our results confirm that patients with Chagas disease living in Bolivia, Argentina and Mexico have been exposed to TrV. Nevertheless, our observations support the fact that TrV is unable to replicate in human hosts.
