Which is an example of secondary prevention in public health?

Secondary prevention in public health focuses on early detection and intervention to halt the progression of diseases or conditions that have already occurred but may not yet be clinically apparent. Routine health screenings are a prime example of this concept. They aim to identify health issues at an earlier stage, allowing for timely treatment that can reduce the severity of a disease and improve health outcomes. By catching diseases early, health screenings can prevent complications and lead to better management of health conditions.

Creating awareness campaigns, implementing health education, and developing supportive community programs all play vital roles in public health but mainly serve purposes associated with primary prevention (preventing an issue from occurring in the first place) or tertiary prevention (managing complications of established diseases). While these initiatives contribute to enhancing overall health and reducing disease prevalence over time, they do not fit into the specific goal of secondary prevention, which is to detect and address existing health issues early on.
