The practice of public health originated in ancient times and has been shaped by various civilizations across different regions. While public health measures have been implemented in all continents, it is generally believed that the practice of public health first originated in Asia. Ancient civilizations in areas such as China and India had well-established systems of public health, including sanitation practices, quarantine measures during disease outbreaks, and documentation of medical knowledge. These early practices laid the foundation for the development of public health strategies that have evolved and been refined over time. Hence, the correct answer is Asia.
