Mayor Bill de Blasio says New Yorkers should call 911 or go to an emergency room if they have possible Ebola symptoms and were in affected countries in the last 21 days.

He said people in that situation should not go to a doctor’s office.

De Blasio said people should not worry about their documentation status if they think they might have the disease.

The mayor noted that flu and Ebola might have similar symptoms. He said it’s important to get a flu shot.
