overseeing day-to-day health issues in a country
Explanation:
The local health departments make sure that the community's health is thoroughly assessed, thus, it is their role to oversee the day-to-day health issues in a country. For example, if there's an infectious disease, they prevent its spread by mandating some policies or protocols that people should follow. It is also their duty to respond to emergency situations that affect the health of the local people.
