Public health is the cornerstone of a healthy society. It focuses on improving the health of communities by preventing disease, promoting healthy lifestyles, and addressing health disparities. Understanding and addressing public health issues is essential for building a thriving, equitable world where everyone has the opportunity to live a healthy life.
