CORONAVIRUS: NY Health Dept. | NY Call 1-(888)-364-3065 | NYC Health Dept. | NYC Call 311, Text COVID to 692692 | NJ Health Dept. | NJ Call 1-(800)-222-1222 or 211, Text NJCOVID to 898211 | CT Health Dept. | CT Call 211

The city’s public Health + Hospitals system will run the program, not the health department, which has done contact tracing for other diseases.

“It means eventually being able to trace, more and more, in our perfect world, every person who tests positive. We want to find everyone who is positive and then trace all of their close contacts. And then everyone who needs help, you got to provide the help and that’s what we’ll do,” de Blasio said.
