Then late this past March, the first cases of Ebola began appearing in a surprising part of the continent. The Ministry of Health in Guinea notified WHO of a rapidly evolving outbreak of Ebola virus disease. The outbreak in Guinea was the first sign the virus had made the jump across the continent.
Ebola then spread quickly to Sierra Leone and Liberia, and then to Nigeria.
As the world learned of the cases, CDC began receiving questions from American hospital labs. They were looking for guidance on how to handle testing for patients who had recently returned to the U.S. from West Africa with potential Ebola symptoms.
If U.S. hospitals were to run laboratory tests on these patients, how could they be sure their staff could safely handle materials that might contain this dangerous virus? Did they need the kind of personal protective equipment they saw CDC scientists using when they were testing for Ebola?
