What public health policies help prevent communicable diseases?

Public health policies that help prevent communicable diseases include vaccination programs, which provide immunity against various Infectious Diseases, and surveillance systems that monitor and track outbreaks. Effective sanitation and hygiene regulations, such as safe water supply and waste management, reduce the spread of pathogens. Additionally, public education campaigns raise awareness about preventive measures, such as handwashing and safe food handling practices, thereby empowering individuals to reduce their risk of infection.
