HMM: The Centers for Disease Control Changed Its Ebola Prevention Page on September 19, 2014. Why? Here’s what they took out:

Because we still do not know exactly how people are infected with Ebola, few primary prevention measures have been established and no vaccine exists.

When cases of the disease do appear, risk of transmission is increased within healthcare settings. Therefore, healthcare workers must be able to recognize a case of Ebola and be ready to use practical viral hemorrhagic fever isolation precautions or barrier nursing techniques. They should also have the capability to request diagnostic tests or prepare samples for shipping and testing elsewhere.

Hmm. There is a vaccine now, sort of, but this gives the impression of avoiding panic at all costs.
