A Health Department is a government agency responsible for protecting and improving public health. It monitors health trends, conducts research, and implements health policies to prevent disease and promote wellness in the community. The department often provides services such as vaccinations, health education, and disease control. Health Departments also collaborate with other organizations, such as hospitals and schools, to address health issues. They may respond to public health emergencies, such as outbreaks of diseases like COVID-19, and work to ensure access to healthcare services for all residents.
