What two characteristics define public health?

The characteristics that define public health are indeed best represented by the combination of science and action. Public health relies heavily on scientific research and methodologies to understand health trends, disease prevention, and the efficacy of various interventions. This scientific approach enables public health professionals to analyze data, assess health needs in populations, and formulate evidence-based strategies to improve health outcomes.

Moreover, the action component highlights the importance of implementing these scientific insights into practical measures. This encompasses a wide range of activities, including community health initiatives, policy development, and health education aimed at improving population health and preventing diseases. Thus, the combination of science and action is fundamental to advancing public health objectives, ensuring that researched knowledge translates into tangible benefits for communities.

While other options touch on important aspects of public health, such as prevention and wellness or the role of data, they do not fully encapsulate the integrated nature of science as the foundational element of understanding health issues and the necessity of action to address these challenges effectively.
