Public health laws are created to balance individual liberties with the health of the community. They authorize public health officials to protect public health and safety through measures like disease monitoring, vaccination requirements, and pollution regulation. While public health laws may infringe on individual rights, courts have generally upheld them when they reasonably serve the greater good. Effective public health also requires collaboration between government agencies and other stakeholders through education, policy, and preparedness for health issues like pandemics, bioterrorism, and natural disasters.
