Public health measures are actions taken 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. Governments and health organizations often implement public health measures during emergencies, such as disease outbreaks or natural disasters. For example, during the COVID-19 pandemic, measures like social distancing, mask mandates, and travel restrictions were introduced to reduce the spread of the virus and protect public health.
