Chagas Disease in Dogs
Can It Spread to Humans?
There are reports that dogs, especially in the southern U.S. and in particular, Texas, may be infected with these parasites and some reports imply there is a danger for humans to become infected because the vectors now reside in the southern U.S. However, the percentage of dogs found to be infected with the parasites is relatively low (about 8.8%) and it is often associated with dogs that are feral, strays, or abandoned. In Mexico, the infection rate of dogs is higher (about 17%-21%). However, all dogs are at some risk to become infected if they are bitten by the vector.
