What is classified as a public health intervention?

A program designed to improve health outcomes in a population is classified as a public health intervention because it actively seeks to address health issues at the community or population level, rather than focusing solely on individual treatment. Public health interventions are aimed at preventing disease, promoting health, and prolonging life through organized efforts and informed choices of society, organizations, public and private, communities, and individuals. These programs can include initiatives such as vaccination campaigns, disease screening programs, education on healthy lifestyles, and policies to promote healthy environments.

While the other options may contribute to healthcare and education, they do not fit the broader scope of public health interventions as effectively. Treatment provided in a hospital is more focused on individual care rather than population health. Educating healthcare professionals primarily addresses knowledge enhancement within the healthcare system and does not directly target community health outcomes. Conducting a survey to assess health needs is an important step in understanding public health needs, but it is more of a data-gathering activity than an intervention designed to enact change or improvement.
