The Public Health Act is a set of laws designed to protect and improve the health of the population. It provides guidelines for sanitation, disease control, and health education. The Act empowers local authorities to take necessary actions to prevent health hazards and promote public well-being. Under the Public Health Act, various agencies, such as the Centers for Disease Control and Prevention (CDC) in the United States, work to monitor health trends and respond to public health emergencies. The Act also emphasizes the importance of community involvement in health initiatives, ensuring that everyone has access to essential health services.
