What is Public Health?

Public health ensures that policies and practices support healthy environments for communities to live, work, and play.

Public health focuses on prevention of illness and promotion of wellness. Those working in public health make sure that policies and practices are in place to help communities prevent illness from occurring and to care for those affected when disaster strikes. Public health has been responsible for some extraordinary achievements over the years, including early sanitation efforts, vaccination programs, smoking cessation, increased access to antibiotics, and addressing present day challenges such as obesity, asthma, autism, Ebola—the list goes on and on.

There's also a huge shortage of public health workers in the national workforce as well as the workforce in New York State.
