One says that he is dizzy and his head hurts, while the other says he thinks he might vomit. Wondering what the boys have gotten into, their mother seeks medical help. After running tests, the doctor informs her that the boys have managed to pick up a hantavirus. It is a very serious strain, Sin Nombre, and they must get treatment straight away. Considering the boys' situation, where do they MOST likely live?
