Public and primary healthcare are critical components of global healthcare systems, playing diverse but interwoven responsibilities in improving population health and providing important medical services. Together, public and primary healthcare may prevent illness, promote health, and offer individuals and communities full medical care. They are complementary parts of healthcare systems. Achieving optimal health outcomes and minimizing health inequities within communities requires effective coordination between public health organizations and primary care physicians. Instead of concentrating on the health of individual patients, public healthcare aims to improve the health of populations, communities, and entire societies. The primary goal of primary healthcare is to offer community-based individuals and families comprehensive, ongoing, first-contact medical care.
