Primordial prevention refers to actions taken to prevent the development of risk factors for a disease in the first place. It involves policies and interventions to avoid the emergence of social, environmental, and behavioral factors that contribute to disease. In this scenario, the country is taking precautions for a disease that has not yet occurred, which aligns with primordial prevention. Primary prevention would focus on preventing the disease itself once risk factors are present, secondary prevention involves early detection, and tertiary prevention involves managing established diseases.
