A Public Health Agency is a government organization responsible for protecting and improving the health of the population. These agencies monitor health trends, conduct research, and implement health programs to prevent disease and promote wellness. They often work in collaboration with other organizations, such as hospitals and community groups, to address public health issues. Public Health Agencies also respond to health emergencies, such as outbreaks of infectious diseases. They provide information and resources to help communities stay healthy and informed. Examples of such agencies include the Centers for Disease Control and Prevention (CDC) in the United States and the World Health Organization (WHO) globally.
