 A second American infected with the potentially deadly Ebola virus arrived at Emory University Hospital on Tuesday from Africa, following the first patient last weekend. People responded viscerally on social media, fearing that we risked spreading Ebola to the United States.
– As Emory University Hospital in Atlanta treats two patients with Ebola, health officials are taking flak for bringing the contagious disease to the US. The head nurse at Emory, however, thinks everybody should calm down. "Those fears are unfounded and reflect a lack of knowledge about Ebola and our ability to safely manage and contain it," writes Susan Grant in the Washington Post.

Hospitals exist to care for the sick and to advance medical knowledge, and the Ebola cases hit both points, writes Grant. Should the US turn its back on two charity workers who selflessly helped others? To do so would be a breach of medical ethics.
