Choice D, 'Health education,' is more related to promoting awareness and knowledge rather than specifically focusing on reducing the impact of an ongoing illness.

Rationale: Corrected Rationale: Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems. It focuses on identifying and understanding the factors that influence the occurrence and distribution of diseases, defects, disability, or death of groups of individuals. Therefore, the correct answer is A. Choice B, vital health statistics, is not the primary focus of epidemiology. While vital health statistics may be used in epidemiological studies, it is not the direct concern of epidemiology. Choice C, environmental sanitation, although important for public health, is not the main focus of epidemiology. Epidemiology is more concerned with the factors influencing disease occurrence and distribution, rather than environmental sanitation. Choice D, treatment of a communicable disease, is more related to clinical medicine rather than epidemiology. Epidemiology is more focused on prevention, control, and understanding the patterns and causes of diseases rather than their treatment.

The education committee focuses on educational programs and initiatives, not specifically on safety policies. The ethics committee is concerned with ethical issues and dilemmas, not safety policies and education.
