The outbreak of Ebola virus centered in West Africa is frightening for many reasons. It was the largest Ebola outbreak ever, claimed thousands of lives; and showed that the deadly infectious disease could travel easily from person to person in the later stages.
Most recently, an American healthcare worker with Ebola was brought to Bethesda, Maryland, on March 13, 2015, and admitted for treatment at the National Institutes of Health (NIH), where there is a high-security containment for infectious disease cases. The patient's clinical status went from serious to critical on March 16th.
