To find out definitively, you need to:
1. Identify specific colleges: Consider major universities in NYC like Columbia University, NYU, CUNY (City University of New York, which has several campuses), etc.
2. Visit their websites: Go to the public health or epidemiology department websites of each college you are interested in. Look for their course catalog, program descriptions, or frequently asked questions (FAQs). These will clearly state whether specific courses or degree programs are offered online or in a hybrid format.
In short, the answer is likely "some do, but not necessarily all, and not necessarily entire degrees". You need to research individual colleges to get a precise answer.
