Ongoing vigilance, people and resources are essential to contain Ebola in West Africa. Seven documented clusters have occurred following control of the epidemic. Recent outbreaks appear to be related to viral persistence in survivors. Rapid and coordinated efforts controlled all 7 flare-ups. CDC maintains a team of 75 staff in the countries affected by the epidemic to build public health capacity and detect and respond to Ebola, and prevent another epidemic.
