Now everyone with a cold is going to have to be tested for Ebola. Even if there is no outbreak here, how much is that going to cost?
The cost will be innocent lives. Once they let in 100's of Ebola cases some Americans will get infected. Some of them will get sent home because hospital isolation areas will be full of flu cases. Those people will have their blood tested and two days later the moonsuit team will show up at their house and take him or her away and disinfect. It may have spread to her family despite precautions.
Meanwhile in the overcrowded isolation unit at the hospital if they are not careful they will spread ebola to some flu patients. They have procedures for disinfecting between patients, but we see health care workers infecting themselves it stands to reason they can infect others as well.
NOTHING compared to one or five million dead.
