On Thursday, New York City Mayor Bill de Blasio declared a state of emergency as the number of confirmed cases in the city jumped from 42 to 95 in a single day.

Mayor Bill de Blasio: “But the last 24 hours have been very, very sobering. Literally, yesterday morning feels like a long time ago. We got a lot of information in the course of the day yesterday. A lot changed then. Then, last night, it just seemed like the world turned upside down in the course of just a few hours.”
