It wouldn't even be in the USA if they actually checked people in Africa before they get on a plane. The news was saying that this guy wanted to fly to America so they sent a questionnaire asking if he has Ebola or had been in the same room as someone with Ebola. He answered no to both those questions while he had physically carried someone with Ebola that he was caring for to their bed. Then after he got to America it was found out that him and his family have the virus so he and his family were told not to leave the house yet he sent his children to school anyways which pretty much let it spread to the other children in that school and then their parents and their parents friends and the chain just keeps going.
Good luck though to you all in Texas.
