The CDC has confirmed the first case of Ebola in the United States. The patient arrived in Dallas after a plane ride from Liberia. He was unaware that he was infected and rode in a regular seat on a regular plane possibly infecting others seated nearby on the flight. The patient was also in touch with family and friends until his symptoms started to appear.
This means that there are a number of possibly infected people milling about in Dallas and other cities with connected flights from the Dallas airport.
Dallas is a major airline hub and it is only a matter of days now until additional cases appear.
If you have not prepared, then you had better hurry. Stock up on your supplies immediately because soon you will not want to be leaving your home. If you live in Dallas, it may already be too late.
