What is going on with the CDC (Centers for Disease Control)?

Yesterday the news reported that the second nurse to acquire Ebola in Texas flew on a plane with a low grade fever and the CDC said she never should have done so. Then the nurse said that she called the CDC and told them that she had the low grade fever and asked if it was ok to fly, and they said yes, as her temperature had not yet reached the level that indicated she had Ebola.

What’s up with that? Does the left hand not know what the right hand is doing? Does this make the CDC look like incompetents?
