Spencer, a 33-year-old physician who works with Doctors Without Borders, came back a week ago from Guinea where he is believed to have been treating Ebola patients.

At the news conference, Gov. Andrew Cuomo said officials believe Spencer came in contact with four people during the time he was infected and symptomatic, and state officials are already talking to those four people.

Those four people include Spencer’s fiancée and two friends – all of whom are healthy, but have still been quarantined, New York City Department of Health and Mental Hygiene Commissioner Dr. Mary Travis Bassett said.

The fourth person who is in contact with the state is the driver of an Uber car, which Spencer took when he went bowling Wednesday night in Williamsburg, Brooklyn, Bassett said. The Uber driver had no direct contact with Spencer, and is not believed to be in any danger, she said.
