He and three other people he had contact with in recent days, including his girlfriend have been placed in isolation at the Bellevue hospital. He's officially the 4th person to test positive on American soil.

"We want to state at the outset, there is no reason for New Yorkers to be alarmed. Ebola is a very hard disease to contract." Mayor Bill de Blasio said.
