Public health is the science and practice of promoting and protecting the health and well-being of communities and populations. It involves identifying and addressing the health needs of populations through the prevention of diseases, injuries, and disabilities, as well as the promotion of healthy behaviors and environments.
Public health professionals work in a variety of settings, including government agencies, non-profit organizations, academia, and healthcare systems, to develop and implement policies and programs that improve the health of communities.
Public health encompasses a wide range of disciplines, including epidemiology, biostatistics, environmental health, health policy, and health education. It also involves collaboration and partnerships across multiple sectors and stakeholders to address complex health issues, such as infectious disease outbreaks, chronic disease prevention, environmental health hazards, and health disparities.
