One year after the Centers for Disease Control and Prevention (CDC) began the largest international emergency response in agencyÂ history, the goal is the same: Get to zero new Ebola cases in West Africa. In March 2014, CDC first learned of an outbreak of Ebola in West Africa. CDC immediately sent a team to the field, initiating what would become the largest international outbreak response in the agency’s 70-year history. Over the past year, there have been 1,910 CDC deployments to West Africa, and nearly 3,000 CDC employees have battled Ebola from the agency’s Emergency Operations Center in Atlanta. Working with the affected countries and our international partners, CDC has been heavily engaged in the international and domestic responses to Ebola. This slide show chronicles the CDC’s progress to date and the work needed to “Get to Zero” cases in West Africa.
