Does this mean we are all going to die soon?

Now it comes out that Thomas Eric Duncan knowingly lied when he was being screen for Ebola contacts before he left Liberia. He knew he'd been exposed to the disease and still crossed the Atlantic and exposed others. The president of Liberia say Duncan will be prosecuted when he returns.

But... I know for a fact there have been HIV/AIDS patients who have knowingly exposed others. They've been prosecuted and locked up to protect the public. Should this be done to Duncan to discourage others from doing the same thing he did?
