Public health measures are strategies implemented to protect and improve the health of communities. These measures can include vaccination programs, health education campaigns, and regulations to ensure clean water and air. They aim to prevent disease outbreaks and promote healthy behaviors among the population. Another important aspect of public health measures is surveillance, which involves monitoring health trends and disease patterns. This helps identify potential health threats early on. Additionally, public health policies may include guidelines for food safety and sanitation to reduce the risk of illness, ensuring a healthier environment for everyone.
