A "Wash Hands" campaign is an example of an individual level health promotion intervention

A “Wash Hands” campaign is considered a population-level or community-level health promotion intervention rather than an individual-level intervention. Individual-level interventions focus on one-on-one strategies tailored to a specific person, such as personalized education or counseling based on individual risk factors. In contrast, hand hygiene campaigns are designed to influence large groups by promoting behavioral change across communities, healthcare settings, or entire populations. These campaigns aim to reduce the transmission of infectious diseases by encouraging consistent handwashing practices among many individuals simultaneously, thereby improving public health outcomes on a broader scale.
