The US State Department recently announced they will be bringing people from African countries who are infected with Ebola to the US for treatment. The expected cost per Ebola patient to be treated is $300,000. You can read the Washington Times article here but here is just a small caption:

The document has been shared with Congress, where lawmakers already are nervous about the administration’s handling of the Ebola outbreak. The memo even details the expected price per patient, with transportation costs at $200,000 and treatment at $300,000.

As with any government projected cost, this will probably go up. Each patient will be different and the costs will skyrocket if the patients turn worse like the patient in Dallas from Liberia.
