What is Public Health?

Public Health is the practice of safeguarding and improving the health of people and communities through education, policymaking, and research.

Professionals in this field address a wide variety of health challenges, such as infectious diseases, health disparities, environmental hazards, and lifestyle-related conditions like obesity or smoking. By focusing on prevention and early intervention, public health ensures that resources are used efficiently to reduce healthcare costs and improve overall well-being.
