What is Public Health?

Public Health is a dedicated field of study that is focused on the prevention of diseases as well as improving the health and well-being of people and communities. Public Health professionals identify all aspects that contribute to a population’s health, both positively and negatively, creating programs and policies that enhance the good and mitigate the bad. In contemporary times, the concept of ‘Health’ in this science now also covers social health and mental health, in addition to physical health well-being.
