Public hygiene refers to the practices and conditions that promote health and prevent disease within a community. It includes sanitation measures such as clean water supply, waste disposal, and pest control. Public hygiene aims to protect the health of the population by reducing the spread of infectious diseases and ensuring a clean environment. Key components of public hygiene involve education, health policies, and community engagement. Programs may focus on vaccination, proper handwashing techniques, and food safety. Organizations like the World Health Organization (WHO) play a crucial role in promoting public hygiene standards globally, helping communities maintain a healthy living environment.
