A Public Health Network is a system that connects various organizations, professionals, and resources to improve community health. It includes government agencies, healthcare providers, and non-profit organizations working together to address health issues, share information, and implement effective health programs. These networks focus on prevention, education, and research to tackle public health challenges such as disease outbreaks, nutrition, and mental health. By collaborating, they can respond more effectively to health crises and promote healthier lifestyles within communities.
